4.- OPERATION

6

The metering pump is activated by a PTFE diaphragm mounted on a piston of
an electromagnet.

When the piston of the electromagnet is attracted, a pressure is produced in
the pump body with an expulsion of liquid from the discharge valve.
Once the electric impulse is finished a spring brings the piston back to the
initial position, with a recall of liquid through the suction valve.

As the operation is simple the pump does not need lubrication, therefore
maintenance is reduced almost to zero.

The materials used for the construction of the pump make it particularly
suitable for aggressive products.

5.- INSTALLATION

GENERAL

7

Install the pump in a dry place and well away from sources of heat and, in any
case, at environmental temperatures not exceeding 40°C. The minimum
operating temperature depends on the liquid to be pumped,bearing in mind that
it must always remain in a liquid state.
Place the pump vertically over a rigid surface totally horizontal.

HYDRAULIC CONNECTION

Properly design either in the suction and injection pipe is required, avoiding long
lenght and bending pipes as much as possible.

ELECTRIC CONNECTION

The electric protection of the motor must be installed and adjusted
following its nominal intensity (overloaded switch disjuntor).

A disconnection dispositive must be installed in case of emergency.

The equipment must be protected to avoid untimely sudden starts.

8

Install a safety valve in a derivation as near as possible
from the pump , in order to protect it and the whole
installation from possible over-pressures. This derivation
Must derive the liquid to a safe place.

To prime the pump, first connect the priming

hose to the priming valve and drive the
other side of the hose to a safety place to
pour the air mixed with product.

Open the priming valve and start the pump

at maximum flow until having only liquid in
the priming outlet.

Confirm with ENT.

Direct mode

The pump works with an input signal of a higher value than the minimum frecuency
(SET1), increasing the frecuency of the injections (flow), proportionally to the
increase of the signal, to the maximum frecuency of the injections (SET2).

Reverse mode

Increasing the value of the input signal means a reduction of the flow. Maximum
value of the input signal in mA at SET1, and the minimum value in SET2.

NOTE: A higher frecuency at SET1 than at SET2 is not allowed, so the reverse
mode can only be set setting a higher value of the signal (mA) at SET1.

Example 1:

Dositec mA, Flow 10 l/h, Pressure 5 Bar, Signal 4-20 mA

4 mA = 0 l/h = 0%
12 mA = 5 l/h = 50%
20 mA = 10 l/h =100%

Example 2:

Dositec mA, Flow 10 l/h, Pressure 5 Bar, Signal 4-20mA programmed in Reverse mode.

4 mA = 10 l/h = 100%
12 mA = 5 l/h = 50%

Water counter gives a pulse to the pump. The pump dosifies 20 injection strokes,
while the pump is dosing pulses from water counter are ignored. Once the pump
has finished 20 strokes, it waits for another pulse of the water counter to start
again.

1XN (M) MODE

Example:
Pump receives a pulse and injects "N" times at the maximum frecuency
(120pulse/min).
When it receives a second pulse, time between both pulses is used to calculate
the injection frecuency so injection strokes are spaced in time, the limit is the
maximum frecuency.

When the pending injection cycles are higher than 4, AL3 is displayed, pump
continues dosifying, but the pending cycles are missed.

1:N MODE

The pump needs to receive N pulses to inject once. N is set for the user.

Example:

- Pump set mode 1:N

- Value: N=20

After receiving 20 pulses of the watermeter, the pump injects once.

The same as 1xN mode, but injection frequency is adapted to the time between
each pulse received. If the pump receives pulses while it is dosing, injection
frecuency is increased if possible.

NOTE: 70 pulses/second is the maximum frecuency accepted from the
watercounter.

PROPORTIONAL MODE

Proportional dosing between the pulses of the water counter, and the pump
injections.

1XN MODE

For each pulse received, the pump injects "N" times. N is set by the user,
frecuency is set in manual mode.

Example:

- Pump set on 1XN mode.

- N= 20

- When the pump receives a pulse, it starts dosing 20 injections. If the pump
receives another pulse while it is dosing, the pulse is ignored. When the pump
finishes the 20 injections, it can accept another pulse.

1XN (M) MODE

Works as 1xN mode, but frecuency of the pump is adjusted to time between pulses
received. If the pump received a pulse while it is dosing, it is memorized and
adjusts the frecuency again.

Overpulse alarm (AL3)

When the number of pulses remaining to inject is higher than 4xN, AL3 is
activated. The pump continues working, but the pending injections are not done.

Example:
Pump receives a pulse, dose "N" injections at the maximum frecuency (120
injection/minute).
At the second pulse received, the pump adjust the injection frecuency to the time
between first and second pulse. Maximum límit is maximum frecuency.

7.- MAINTENANCE

Periodically check the chemical tank level to avoid the pump
operates without liquid. This would not damage the pump, but
may damage the process plant due to lack of chemical.
DOSITEC series dosing pumps are all supplied with level control
setting. The level switch is not included therefore to be ordered
separately.
Level control stops pump operation once the level into the
chemical is lower then the level switch,activating a L.E.D. on the
pump .

Check the pump operating condition at least every 6 months,
pump head position,screws, bolts and seals; check more
frequently when aggressive chemicals are used.

Is recomended to clean periodically the hydraulic part(valves and
filter). Cleaning frecuency will depend on the aplication.

Before any maintenance operation check:

The pump is stopped and disconnected from the electric supply.

There is no pressure neither inside the head nor in the impulsion
pipe. It is advisable to empty the head before opening it.

The staff in charge of the maintenance will use the adequate
protection means in order to manipulate the dosed liquid.

CAUSE

Valves not clean

Damaged valves

Filter not clean

Power supply
failure

START failure

Power supply
failure

PROBLEM

The pump gives pulses but
doesn’t inject

The pump doesn’t give
any pulse and LED are off

The pump gives only one
pulse

The pump doesn’t give
any pulse and green LED
is on and red LED is off

Pump pulses are not
constant

TROUBLE SHOOTING

MECHANICAL FAULTS

As the system is quite robust there are no apparent mechanical problems.
Occasionally there might be a loss of liquid from the nipple because the tube nut
has loosened, or more simply the discharge tubing-has broken.
Very rarely there may be losses caused by the breakage of the membrane, or by
the membrane seals in which case they have to be replaced by disassembling the
four screws of the pump head, when re-mounting the pump head ensure that the
screws are replaced properly, along with “O” ring.
After repair, the metering pump will need to be cleaned of additive residues which
can damage the pump case.

35

SOLUTIÓN

Remove the suction and injection
valves, clean them , and assemble
them in the same position.

When the parts are swallen, check
valve material against a chemical
compatibility chart and fit the correct
material.

Clean the filter

Chech the power supply. If it still
doesn’t work contact with the
Technical Service

Press START/STOP.
If it still doesn’t work contact with the
Technical Service.

Check the input voltageis within +/­10% rated voltage

Disconnect the pump and contact
immediately to the Technical Service
