which do not accord with the terms of this warranty shall not be binding upon Watson­Marlow Limited unless expressly approved in writing by a Director or Manager of Watson­Marlow Limited.

Information for returning pumps

Equipment which has been contaminated with, or exposed to, body fluids, toxic chemicals
or any other substance hazardous to health must be decontaminated before it is returned
to Watson-Marlow or its distributor. A certificate included at the rear of these operating
instructions, or signed statement, must be attached to the outside of the shipping carton.
This certificate is required even if the pump is unused. If the pump has been used, the
fluids that have been in contact with the pump and the cleaning procedure must be
specified along with a statement that the equipment has been decontaminated.

Safety

In the interests of safety, this pump and the tubing selected should only be used by
competent, suitably trained personnel after they have read and understood this manual,
and considered any hazard involved.

Any person who is involved in the installation or maintenance of this equipment should be
fully competent to carry out the work. In the UK this person should also be familiar with
the Health and Safety at Work Act 1974.

This symbol, used on the pump and in this manual, means: Caution, risk
of electric shock.

This symbol, used on the pump and in this manual, means: Caution, refer
to accompanying documents.

This symbol, used on the pump and in this manual, means: Do not allow
fingers to contact moving parts.

There are dangerous voltages (at mains potential) inside the
pump. If access is required, isolate the pump from the mains
before removing the cover.

Recommended operating procedures

DO keep delivery and suction lines as short as possible using a minimum number of swept
bends.
DO use suction and delivery pipelines with a bore equal to or larger than the bore of the

http://www.watson-marlow.it/pdfs-global/m-624Di-gb-01.htm[10/07/2012 13:59:15]

Watson-Marlow Bredel E-Manuals

tube fitted in the pumphead. When pumping viscous fluids, the losses caused by increased

friction can be overcome by using pipe runs with a cross sectional area several times
greater than the pumping element.
DO fit an extra length of pump tube in the system to enable tube transfer. This will extend
tube life and minimise the downtime of the pumping circuit.
DO keep the track and rollers clean.

The self-priming nature of peristaltic pumps means valves are not required. Any valves
fitted must cause no restriction to flow in the pumping circuit.

When using Marprene tubing, after the first 30 minutes of running, re-tension the tube in
the pumphead. Open the guard, hold the tubing at one port whilst pulling the tube tight
through the second port. This is to counteract the normal stretching that occurs with
Marprene which can go unnoticed and result in poor tube life.

Tube selection The chemical compatibility list published in the Watson-Marlow catalogue
is only a guide. If in doubt about the compatibility of a tube material and the duty fluid,
request a tube sample card for immersion trials.

Installation

The 624Di is suitable for single-phase mains electricity supplies only.
To ensure correct lubrication of the gearbox the pump should be run only while its feet are

standing on a horizontal surface. The pump should be positioned to allow a free flow of air
around it.

Remove the small transparent plate on the rear panel to gain access to the voltage
selector and terminal block.
Set the voltage selector to either 120V for 100-120V 50/60Hz single-phase AC
supplies or 240V for 220-240V 50/60Hz single-phase AC supplies.
Route the mains supply cable through the entry point to the right of the recess, and
couple the cable to the terminal block as shown on the rear panel.
There are two alternative connectors. One accepts 20mm rigid or flexible conduit,
and the other accepts three core 0.75 square millimetre PVC sheathed mains cable
(via the screwed adapter supplied) so that a mains lead can be used.
Ensure that the mains lead is securely retained in the strain relief gland so that IP55
ingress protection is maintained.
Securely replace the transparent plate and the gasket over the recess.

1. Armoured cable strain relief gland GR 0018

2. Washer GR 0019

3. Strain relief gland SL0020

Ingress protection standard will be compromised if the transparent plate
is not replaced.

Rear panel recess

The pump rear panel recess houses the following:

1. Fuse holder

2. Terminal block

3. Voltage selection switch

http://www.watson-marlow.it/pdfs-global/m-624Di-gb-01.htm[10/07/2012 13:59:15]

Watson-Marlow Bredel E-Manuals

to ensure the highest accuracy possible.

Troubleshooting

Should the pump fail to operate, make the following checks to determine whether or not
servicing is required.

Check that the power switch is on.
Check the mains supply is available at the pump.
Check the voltage selector switch is in the correct position.
Check the fuse in the mains socket.
Check that the pump is not stalled by incorrect fitting of tubing.

User interfacing

When powering-up the pump the user will be taken into the main menu.
Use the Step key to move between menu options. Use the Enter key to confirm settings.

Use the number keys to enter in settings. Use the Up or Down key to increase or decrease
set values in the pump software i.e. ramp settings, date, rpm etc.

Dose permits the set-up of dose programs for dispensing. A dose can be initiated by using
the Start button or external switching. The pump will allow up to 26 dosing programs to be
stored and recalled at any time. A printer can be connected to the pump for recording of
dispense runs. Batch and operator codes must be entered when using a printer.

Cal allows the pump to be calibrated for accurate dosing.
Manual allows continuous transfer/fluid metering via keypad control.
Auto enables analogue or RS232 control.
Setup displays and controls the user and factory settings for the correct operation of the

pump.
The speed/volume flow rate of the drive is governed by the pumphead and tubing selected.

Dosing procedure

The Dosing program is outlined in the technical data section of the operating instruction in
a flow chart format. Each step in the procedure is described to provide full understanding of
the procedure.

Within the technical data section are mean values for dose time guidelines and accuracy
figures recorded using Silicone tubing at zero suction and pressure. For the highest
accuracy use small-bore tubing and maximum roller passes. Always use a calibration dose

Watson-Marlow Bredel E-Manuals

Print audit routines

If a printer is connected, the completion of a dose run will automatically call the print
routine. The first request will be to enter the operator ID.

Up to 16 characters can be entered. Digits and the decimal point are entered directly from
the keypad. Alpha characters are entered by pressing Up or Down which call A to Z and Z
to A respectively in circular rotation.

An alpha character is embedded by pressing Step. A numeric character is entered by
pressing Step, any other numeric character, the decimal point or Up or Down.

On pressing Enter, the pump will request the input of a batch number.
Again, up to 16 characters can be entered as for the operator ID. When Enter is again

pressed, the following information is printed out: date, time, dose size, specific gravity,
dose interval, number of doses, initial ml/rev, recalibration data, operator ID, batch
number and number of doses delivered.

Following the print-out a repeat dose option will be given.

Single dose command

Single doses can be dispensed on demand, with a count of the number of doses being
kept.

Set the interval time to 0 SECONDS and the number of doses to 1.
To start single dosing, press Start or use an external start dose switch. The display will

indicate the total number of completed doses up to a maximum of 99,999, after which the
counter will restart at 0: dose 100,001 would be shown as 1.

Calibration procedure

Calibration of the 624Di is based on informing the pump under Cal of the pumphead and
tubing which are to be used. Alternatively a calibration dose can be used. The calibration
dose will run for a maximum of 4 minutes, but can be stopped at any time up to 4
minutes. The longer the calibration dose, the more accurate the calibration. Entering into
the pump the physical volume or mass to complete the procedure will allow the pump to
take into account ambient conditions and also the viscosity of the fluid.

Manual operation

Switch power on.
Change the set speed by pressing the Up or Down key. The minimum speed of the
624Di is 4 rpm.
Change direction by pressing the CW/CCW key. Indication of direction of rotation is
provided via the LCD display.
Select the maximum speed: press the Up key and the Max key together. Select the
minimum speed: press the Down key and the Max key together.
Press Start to start the pump. Press Stop to stop the pump.

Auto operation

The pump will accept external control signals through the 25-pin cage clamp connector on
the back panel. Remove the cover plate, ensuring that the gasket is not damaged. Feed
the control wires through the cable glands and connect via the sprung cage clamps.

Analogue

This function enables the pump speed to be controlled via an external analogue process
signal. Pressing Enter at analogue will call a confirmation of the analogue control signal
settings. These can be reset under Setup (see section covering pump setup).

RS232

This facility gives full pump functionality under RS232 closed loop control via the 4-pin
cage clamp. Up to 16 pumps can be linked while retaining individual pump control by using
lead PR0036. A network kit is available from Watson-Marlow which includes Pumpnet 2, a
DOS-compatible control program, and leads.

Setup

ROM - provides user with software identification.
Date/Time - Set during manufacture but can be reset to user requirements.
Beep - Audible signal on/off.
Ramp - Rate of acceleration/deceleration of the pump to/from maximum set speed at the

beginning/end of a dose. 0 setting signifies no acceleration delay to maximum speed, 5
signifies the longest acceleration delay to maximum speed.

Drip - Brief reversal of the motor on dose completion ensures no extra drips of fluid are
dispensed. 0 means no reverse and 5 means maximum reverse.

Baud - Speed of signal transmission. Default setting 9600, range of setting include 1200,
2400, 4800, 9600.

Auxiliary - Monitor the pump dosing or motor state/direction of rotation using 2 high (5V)
/low (0V) auxiliary signals outputted via the pumps 25 pin cage clamp connector. Auxiliary
signals can be used, for example, to command a turntable or conveyor to move when a
dose has been completed.

http://www.watson-marlow.it/pdfs-global/m-624Di-gb-01.htm[10/07/2012 13:59:15]

Watson-Marlow Bredel E-Manuals

Line 1 can be set to change state every time the motor runs, or only when the motor runs
to dispense a dose. The signal can be set high or low when the motor runs. Line 2 changes
state when the pump direction is changed. The screens allow the signal to be set high or
low when the output shaft rotates clockwise.

Pump - When under RS232 control each individual pump must be identified. Select a
number from 1-16.

Max - Sets when the pump can be primed at maximum speed. Standard setting means
Max is enabled during Manual and Setup. Always enabled means the unit can be primed at
any time.

Default - Press Enter at "Yes" to restore factory defaults.
Autostart - If set to On when in Manual mode only, Autostart will allow the pump to

restart pumping automatically after power-up following a mains supply interruption. If set
to Off the pump will restart and return to the Main Menu.

Signal - Step to the desired process signal for analogue control and press Enter. Options
available are 4-20mA, 0-10mA, 0-20mA, 0-5V, 0-10V These signal ranges correspond to
0-200rpm speed control. A confirmation screen will verify settings chosen. If the signal
type required is not shown then use the "program" option to enter in the required signal
levels. The pump is controllable by an analogue process signal of up to 30V or 32mA. The
pump will provide an increasing flow rate for a rising control signal (non-inverted response)
or an increasing flow rate for a falling control signal (inverted response).

For voltage modes a stable, variable DC voltage
source can be used in conjunction with a DC
voltmeter, (max 30V DC). (Refer to the 25 pin cage
clamp connector wiring detail as an example of
control circuitry) Circuit impedance 100kW. Polarity
set for non-inverted response. Reverse polarity for
inverted response.

For current modes the same DC source can be used
in conjunction with a DC milliampere meter,
(maximum 32mA). (See 25 pin cage clamp connector
detail). Circuit impedance 250W. Polarity set for non­inverted response. Reverse polarity for inverted
response.

Trim - This function will match the pump's signal
conditioner to the analogue process control signal if
they do not fully coincide. The user will be asked to
apply zero, 20% and the maximum voltage or
current that is required to be the control signal. Press
Enter after adjusting the process signal to each input level.

Never apply mains voltage across pins on the 25-pin cage clamp
connector. Up to 5V TTL may be applied to pins 7 and 5, but do not apply
voltage across any other pins. Failure to heed this warning could cause
permanent damage not covered by warranty. Do not use the mains
power switch to control the pump for a high repetition of stop starts.
The auto-control facility should be used.

Remote control

Pause dose This function will pause a dose for as long as a remote switch remains closed

then allows the dose to continue when the switch is opened. Under Manual mode it will
also act as a remote stop/start. Connect remote switch as in the Stop/Start diagram. Open
to run pump, close to pause or stop pump.

http://www.watson-marlow.it/pdfs-global/m-624Di-gb-01.htm[10/07/2012 13:59:15]

Watson-Marlow Bredel E-Manuals

Stop/Start Connect remote switch between pins 7 and 16 of the 25-pin cage clamp

connector. A TTL compatible logic input (Low 0V, High 5V) may be applied to pin 7. Low
input stops the pump, high input runs the pump. With no connection, the pump will default
to running.

Direction Connect remote switch between pins 5 and 16 and disable the front panel
reversing control by linking pins 6 and 18 of the 25 pin cage clamp connector. Open switch
for clockwise rotation, close for counter-clockwise. Alternatively a TTL compatible logic
input (Low 0V, High 5V) may be applied to pin 5. Low input will run the pump in a counter­clockwise direction, High input in a clockwise rotation. No connection; the pump will default
to clockwise rotation.

Speed A remote potentiometer nominally 1kW and 2kW minimum 0.25W should be wired
as shown. When using a remote potentiometer, do not apply a voltage/current control
input signal at the same time. The pump must be calibrated for 0-12V analogue signal
control under the "PROGRAM" option of Signal in Setup. Alternatively, the potentiometer
may be used for the calibration procedure, instead of using the minimum and maximum
analogue process signal settings, if it is set to its minimum and maximum positions.

Tachometer output This facility can be used to indicate motor speed or total the number
of motor revolutions.

Footswitch A footswitch or handswitch will initiate the dose. The 624Di includes software
protection against spurious signals caused by bouncing of the switch contacts. This feature
is permanently activated (software setting fixed on "other") and only switches without
hardware debouncing should be used.

Watson-Marlow Bredel E-Manuals

Care and maintenance

The only scheduled maintenance required for the 624Di is inspection of the motor brushes
and their replacement before their length is less than 6mm. The life of the brushes will
depend on the duty of the pump, but is expected to be a minimum of 3,000 hours at
maximum speed.

If the pump requires cleaning, use a mild solution of detergent in water after removing the
pumphead. Do not use strong solvents.

For gearbox rebuilds, use Lubriplate GR-132 (Bodine reference LG-23) only. This is a
lithium combination type thickener, NL GI No.1 grade, non-corrosive extreme pressure
lubricant. This product is water-resistant and resistant to a large degree to most other
contaminants.

Guard safety warnings

The 624Di will be remotely stopped and display a warning if the guard is opened during
operation. This safety feature is enabled under Manual, Dose, Analogue and RS232
operation.

620RE, 620RE4 and 620R Key safety information

Before opening the pumphead guard please ensure that the
following safety directions are followed.

For close-coupled drives, ensure that the pump is isolated from mains voltage.
Ensure that there is no pressure in the pipeline.
If a tube failure has occurred, ensure that any product in the pumphead has been
allowed to drain through the controlled waste to a suitable drain.
Ensure that protective clothing and eye protection are worn if hazardous products
are being pumped.

620RE, 620RE4 and 620R Safe-guarding

Primary safety on 620 series pumps is provided by the tool-lockable pumphead
guard. On electrically-powered cased 600 series pumps, secondary (backup)
protection is provided in the form of an electrical interlock which stops the pump if
the pumphead guard is opened (and only for so long as the guard is opened). The
electrical interlock on cased pumps should never be used as primary protection.
Always disconnect the mains power supply to the pump before opening the
pumphead guard.
Only primary protection through the tool-lockable guard is provided on pneumatically
powered 620 series cased pumps. Only primary protection through the tool lockable
pumphead guard is provided on 620 series pumps fitted with industrial AC motors,
but an interface kit to allow mains power to be switched by the pumphead guard
interlock is available as an extra-cost option.

620RE, 620RE4 and 620R Pumping conditions

Pressure and viscosity

All pressure values in this operating instruction, from which performance and life
figures have been calculated relate to peak pipeline pressures.
Although rated to 4 bar working pressure, this pump will generate in excess of 4 bar
working pressure if pipeline restrictions are in place. In instances where it is critical
that a working pressure of 4 bar is not exceeded, pressure relief valves should be
installed in the pipeline.
For pumping duties of 2-4 bar pressure, only close coupled pumps should be used,
fitted with 73 Shore hardness Marprene/Bioprene or standard STA-PURE tube
elements. "M" in the tube element’s product order code denotes suitability for high
pressure use.
When pumping duties of 0-2 bar pressure, use close coupled or cased pumps fitted
with 64 Shore hardness elements or the standard range of continuous peristaltic
pump tubing.
Viscosity handling is maximised by using 73 Shore hardness Marprene/Bioprene or
STA-PURE tube elements in the pumphead.
Ensure that there is always a minimum of one metre of smooth bore flexible tubing
connected to the discharge port of the pumphead. This will help minimise any
impulse losses and pulsation in the pipeline. This is especially important with viscous
fluids and rigid pipework.

A correctly engineered installation will promote the best possible tube life, so please ensure
that the following guidelines are followed:

Avoid tight pipeline bends, pipe reducers and excessive lengths of smaller bore
tubing than that in the pumphead, particularly in pipelines on the suction side.
Ensure that connecting pipe work and fittings are suitably rated to handle the
predicted pipeline pressure.
If rigid pipe work comes in close proximity to the pumphead, a drop out section of
pipe work will simplify tube replacement.
Ensure that the controlled waste blanking plug is in position if the controlled waste
port is not in use. See below.

http://www.watson-marlow.it/pdfs-global/m-624Di-gb-01.htm[10/07/2012 13:59:15]

Watson-Marlow Bredel E-Manuals

It is advisable to use controlled waste pipe work if pumping hazardous, aggressive
or abrasive fluids or products which will harden in contact with air.
When connecting waste pipe work to the controlled waste port using the coupling
adaptor supplied, ensure that there is adequate clearance underneath the
pumphead. Waste pipe work should run to a suitable container or drain.
The leak detector installation procedure is included in the leak detector kit.
If unsure of an installation please contact your local Watson-Marlow Technical
Support Office for further assistance.

620RE, 620RE4 and 620R General operation

Opening the pumphead guard

Unlock the guard with a 5mm Allen key or a screw driver.
Open the guard to its full extent. This creates the maximum clearance between the
tube ports and guard to remove the tubing.

Engaging/disengaging the rollers

The extent of travel of the roller release levers is indicated below. Do not try and
force the levers beyond their normal extent of travel as this will damage the rotor.
To engage the rollers snap the roller release levers counter clockwise making sure
that the rollers locked out against the tubing. To disengage the rollers, snap the
release levers clockwise to their disengaged position. For high pressure tubing
elements or four roller pumpheads, the 5mm Allen key can be used to aid leverage
when engaging/disengaging the rollers with the release levers.

Make sure that fingers are clear of the front face of the rotor hub
when using the roller release levers.

Pre-load checks

Before loading tubing, ensure that all rollers rotate freely, that the tube ports and
location grooves are clean and that if in use, the controlled waste pipe work is free
of any obstructions.

Closing the pumphead guard and start-up

Ensure that the guard seal is clean, replacing it if necessary.
Ensure that the rollers are engaged and locked out against the tubing
Close the guard and push it against the track until the latch engages.
Connect suitable pipe work to the pumphead using the appropriate connectors for
the tube element.

Continuous tubing clamp location in 620R pumpheads

Select the appropriate tube clamp set for the tubing size to be used.
Locate the two "U"-shaped track clamp halves into the pumphead ports (The "U"­shape ensures correct loading)

http://www.watson-marlow.it/pdfs-global/m-624Di-gb-01.htm[10/07/2012 13:59:15]

Watson-Marlow Bredel E-Manuals

Locate the corresponding guard clamp halves which have raised "T" locating

sections, into the slots on the inner guard face above and below the guard hinge.
Push and slide into their locked position.
Closing the guard will align the two halves of the clamp around the tubing.

620RE and 620RE4 tube element loading

620RE element pumpheads are factory set to accept Watson-Marlow LoadSure tube
elements. Pumping performance will be adversely affected if LoadSure elements are
not used.
Disengage rollers
Locate one of the "D"-shaped flanges into the lower port. (The "D" flange ensures
that the element can only be loaded correctly).
Wrap the tube element around the disengaged rollers of the rotor.
Locate the second "D"-shaped flange into the upper port.
Ensure the flat face of each "D" flange sits flush to the flange sealing face of the
track.
Engage rollers
Close the guard and push it against the track until the latch engages.

Tube element loading

620RE, 620RE4 and 620R Continuous tube loading

620R continuous tubing pumpheads are factory set to accept Watson-Marlow 600
series 3.2mm wall tubing. Pumping performance will be adversely affected if
Watson-Marlow tubing is not used.
Select the tube clamp set which is correct for the tubing size to be used.
Disengage rollers
Locate one end of the tubing into the lower port "U" clamp and hold firmly in
position.
Wrap the tubing tightly around the retracted rollers, making sure that there is no
twisting through its length.
Locate the other end of the tubing into the upper port "U" clamp.
Hold both ends of the tubing in one hand maintaining tension around the retracted
rollers.
Engage rollers
Close the guard and push it against the track until the latch engages
Ensure that continuous tubing is not loosely clamped at the pumphead ports.
Ensure that when the pump is re-started all of the rollers have re-engaged. A roller
which has not re-engaged will "click" continuously. No damage will occur if this
happens but the roller should be re-engaged manually using the 5mm Allen key.
Please refer to the Troubleshooting section.

Continuous tube loading

http://www.watson-marlow.it/pdfs-global/m-624Di-gb-01.htm[10/07/2012 13:59:15]

Watson-Marlow Bredel E-Manuals

620RE, 620RE4 and 620R Tube element or continuous tube removal

Unlock the guard and disengage the rollers.
Disconnect the tubing from the external pipeline.
Remove the tubing from the pumphead.

620RE, 620RE4 and 620R Maintenance

Scheduled maintenance

The stainless steel pumping rollers run on sealed bearings and do not require
lubrication.
Remove the rotor and lubricate the follower rollers and roller engaging mechanisms
with a lithium-based grease. This should be carried out every six months for
intermittent duties and every three months for 24 hour duties.
If fluid is spilled inside the pumphead, flush the pumphead out with water and mild
detergent as soon as possible. If specific cleaning agents are required to clean the
spillage, please consult Watson-Marlow Technical Support Office before proceeding,
in order to confirm chemical compatibility.
If the rotor needs to be removed, refer to the guidelines below.

Roller adjustment

620 pumpheads have provision for adjustment to reset the roller/track gap to compensate
for wear after extended service in arduous applications.

Roller/track gaps can only be accurately judged without tubing in the pumphead. The gap

http://www.watson-marlow.it/pdfs-global/m-624Di-gb-01.htm[10/07/2012 13:59:15]

Watson-Marlow Bredel E-Manuals

should be 4.6mm for 3.2mm wall tubing and 5.5mm for LoadSure elements.

If the gap is more than 0.2mm greater than these dimensions, the following may be
carried out:

Note the number on the roller arm to which the engraved line on the hexagon­headed main roller pin corresponds.
Remove the circlip (snap-ring) and roller pin.
Relocate the main roller pin, resetting the engraved line to one number lower. For
example, if the engraved line was at "-1", reset it to "-2" to reduce the roller track
gap.
Ensure the roller pin is correctly seated into the roller arm thrust washer. Replace
the circlip.

Rotor removal and re-location

Remove the rotor cover and central locating bolt using a 5mm Allen key. Pull the
rotor off the keyed shaft, remove the key and clean thoroughly. Do not use tools to
lever the rear face of the rotor away from the inner face of the track, it should come
off by hand.
To replace the rotor, locate the key into the keyway and apply a thin layer of grease
over the shaft and key. Align the keyway of the rotor to the shaft key and slide the
rotor into position, ensuring that a positive "stop" is achieved and ensure that the
full length of the drive shaft is fitted into the rotor.

Do not force the rotor into position. The rotor will slide into place easily if correctly
aligned.
Tighten the hexagonal locating bolt to a nominal torque of 10Nm using a 5mm Allen
key.
The rotor bolt, which is impregnated with "Loctite 218" thread lock, should be
subjected to a maximum of three removals/relocations before renewal. To avoid
rotor bolt renewal after three removals, apply "Loctite 222" thread lock to the rotor
thread before relocation. This is critical to ensure prolonged, secure location of the
rotor hub to the drive shaft. Failure to complete this action will invalidate the
terms and conditions of the pumphead warranty.
Replace the rotor cover.

When closing the guard, check it does not make contact with the rotor. If it does, then the
rotor has been fitted incorrectly. Re-open the guard, remove and refit the rotor, and close
the guard.

http://www.watson-marlow.it/pdfs-global/m-624Di-gb-01.htm[10/07/2012 13:59:15]

Watson-Marlow Bredel E-Manuals

Track removal (cased drives)

Remove the rotor.
Disconnect the controlled waste pipework if attached.
Loosen the two track-retaining screws using a screwdriver.
Withdraw the track slightly from the front plate to expose the guard interlock
connection.
Disconnect the guard interlock by manually removing the cable plug from the track.
Withdraw the track fully from the cased drive.

Track re-location (cased drives)

Ensure that the track is clean and that the spacer washer and gearbox boss
alignment rings are still in position.
Offer the track up to the front panel of the cased drive and re-connect the guard
interlock cable plug.
Fit the track over the gearbox boss.
Align the track horizontally so that the location holes are aligned with the front plate
threaded holes.
Tighten the two retaining screws using a screwdriver.
Re-connect the guard interlock controlled waste pipework if required.

620RE, 620RE4 and 620R CIP and SIP

General

Unlock the guard and disengage the rollers within the tube zone.
Close the guard and squeeze against the track until the latch clicks.
Observe a 1m safety area.

CIP

LoadSure tube elements and continuous tubing can be cleaned using CIP processes.
Ensure that the tubuing material is chemically compatible with the cleaning agent
that is to be used.
If cleaning agents are spilled over the pumphead, wash down immediately.
Ensure that controlled waste pipework is fitted to allow a safe release of cleaning
agent in the event of a tube failure.

SIP

Only STA-PURE tube elements can be used in a steam in place sterilisation
processes.
STA-PURE tubing elements can be sterilised to 3A Class two and FDA minimum
recommended standard which is 121C (250F) at 1bar (14.5 psi) saturated steam for
20 minutes.
Monitor the process continuously .
If a tube failure occurs, shut down the process. Do not touch the pumphead until a
20 minute cooling period has been observed.

625L Pumphead

The twin offset track design of the 625L utilises 4.0mm wall double-Y tube elements to
overcome pulsation for accurate dosing and dispensing. The 625L accepts Silicone and
Marprene tubing up to 16.0mm bore. Use 4.0mm wall tube for transfer for the highest
performance and improved viscous fluid handling.

Alternatively the 625L will run with two separate tubes although some channel to channel
variance and minimal pulsation may be experienced. For separate tube fitting or twin tube
inlet to single tube outlet fitting tube clamping blocks must be used.

625L Installation

Remove the mounting plate cover and track from the 625L. Locate 625L to pump. Tighten
top and bottom mounting plate screws. To remove the pumphead lift off the mounting
plate cover and track, loosen the top and bottom mounting plate securing screws and ease
pumphead away from the pump.

down the track locating levers. (See pumphead installation).

Twin inlet tubes

Lift the track locating levers and remove the track. Twist and remove the 625L inlet
clamping peg. Connect the twin inlet tubes and outlet tube using the appropriate Y-piece
connector and clamps. Fit the inlet tubes into the correct size clamping block. Locate the
clamping block onto the 625L (push down and twist locking fastener to secure). Stretch the
tubes over the rotor and locate the Y-piece end of the element over the second 625L
clamping peg. Replace the track and push down the track locating levers.

Two independent tubes

Lift the track locating levers and remove the track. Twist and remove the 625L clamping
pegs. Fit the two tubes into the correct size clamping blocks. Distance between blocks =
230mm for up to 8.0mm bore; 240mm for 12.0mm and 16.0mm bore. Fit the inlet tube
clamping block to the 625L. Stretch the tubes over the rotor and fit second tube clamping
block to the 625L. Replace the track and push down the track locating levers. When using
Marprene it is important to check the distance between the clamping blocks after 30
