The diaphragm pump can be applied in all areas where an oil­free, dry vacuum is required.
Particularly the pump is suitable as backing pump for many
Pfeiffer Vacuum turbopumps in applications involving light
gas loads only.

3. Installation

3.1. Setting Up The Pump And Location

➡ Place pump on a smooth, even surface.
➡ Anchor the pump if it is to be erected in a stationary positi-

on.
➡ Avoid mechanical stresses due to rigid connections. Insert

elastic hoses or resilient elements as couplings between

the pump and rigid pipes.
➡ Anchoring is not necessary if the pump is not erected in a

stationary position.

➡ Maximum ambient temperature +12 ... +40 °C.
➡ Where rack installation is involved, ensure adequate venti-

lation. If pump is installed above 1000 m above mean sea

level check compatibillity with applicable safety require-

ments, e. g. DIN VDE 0530 (motor may overheat due to

insufficient cooling).

3.2. Connecting The Vacuum Side

– Remove locking cap on intake connection.
– Make connection between the vacuum system and pump

as short as possible.
–Connect pump with intake connection to the apparatus.
–If liquid - which would generate vapours - is present in the

system to be evacuated, a condensate trap must be fitted

upstream of the pump.

3.3. Connecting The Exhaust Side

Pressure can rise to dangerous levels in exhaust
lines. Therefore, lay exhaust side lines without
shut-off units. Do not connect the exhaust side
with a closed system on account of the danger

of bursting.
In certain applications, exhaust gases and vapours can be
very hot and represent a health and/or environment hazard.
Lay lines from the pump sloping downwards so that
condensate cannot run back into the pump, otherwise fit a
separator.

3.4. Connecting To Mains Power

The pump is driven by AC motors with the following possible
variants:
230 V + 5% / -10%, 50 Hz
120 V + 5% / -10%, 60 Hz

Power connections must comply with local

regulations. Voltage and frequency information

given on the rating plate must correspond to the

mains voltage and frequency values. The pump

may only be connected to mains current with

earthed conductor.

WAR N IN G

CAUTION

Pump versions where the thermostatic winding
protection protrudes must be appropriately
wired to ensure the motor is protected.

CAUTION

4.3 Intermittent Operations

To prolong the life of diaphragm pumps, intermittent
operations can be selected with lesser gas throughputs of

< 0.18 mbar l/s. This means that, dependent on the turbo
pump power take-up, the backing pump will be switched on
and off. Turbo pump power take-up is dependent on the fore­vacuum pressure and gas throughput.
–By comparing the power take-up with an upper and a

lower limit value, the relative switch-on duration with
lesser gas throughputs can be reduced to approx. 1 to 60%

–To avoid too frequent switching on, the buffer volume in

the fore-vacuum line should amount to < 0.5 liter from
approx. 0.018 mbar l/s.

Possible intermittent operations variations are shown in the
following diagram:

4. Operations

4.1. Important Information

Before starting, ensure that impermissibly high

pressures cannot build up on the pressure side.
Interchanging the connections causes
dangerous excess pressure levels.

The pumps should only start, when the pressu­re difference is max. 1 bar between admission and exhaust,
because the motor will be blocked and damage.

When the pump is running, surfaces and motor

casing become hot.

WAR N IN G

CAUTION

4.2 Switching ON/OFF The Pump

The pump can be switched on and off at all times.

Prevent internal condensation, transfer of

liquids or dust. The diaphragm and valves will

be damaged, if liquids are pumped in significant

amount over lengthy periods!

If the pump is subjected to condensates it

should be allowed to run for a few minutes

under atmospheric pressure before switching

off.

6. Maintenance

6.1. Precautionary Measures During Mainten­ance Work

Whenever working on the pump ensure the

motor cannot get switched on.
If necessary, remove pump from the system for
inspection. Before dismantling allow the pump
to cool down.

➡ Only dismantle the pump as far is necessary to effect

repairs.

➡ Use only benzin or the like for cleaning. Do not use

solvents.

6.2. Cleaning And Replacing Valves And
Membranes

Under normal operating conditions, the pump is maintenance
free. The valves and the diaphragms are wear parts. If the
rated ultimate vacuum is no longer achieved, the pump interi­or, the diaphragms and the valves must be cleaned and the
diaphragms and valves must be checked for cracks or other
damage.
Depending on individual cases it may be efficient to check
and clean the pump heads on a regular basis. In case of
normal wear the

.

There can be different numbers of washers 17

in each membrane head. Ensure the correct
assignment for mounting when dismantling the
membrane heads. Don’t confuse the washers

17.

6.3. Dismantling The Membrane Head

➡ Allow the pump to cool down before dismantling.
➡ Using an SW 14 key, unscrew direct screw joint (20) of

interhead connection (10) on diaphragm head 1 (see marks
on the housing).

➡ As far as possible place pump on its side so that the head

to be dismantled points up.

➡ Using an SW 3 key, unscrew the four Allan head screws

(11) and remove head cover (12), taking care with the two
valve plates (13) and sealing rings (14).

➡ Remove intermediate plate (15).
➡ Use a small screwdriver to carefully ease out diaphragm

(16) and manually unscrew from the connecting rod (right­hand thread). Look out for possible washers (17).

➡ Clean all parts with alcohol and examine diaphragms,

valves and seals for possible damage and renew as
necessary. If a new diaphragm is to be fitted, the washers
(17) of the old diaphragm must be used again otherwise
the pump will not attain the required pressure.

CAUTION

CAUTION

6.4. Assembling The Membrane Head

➡ Assemble all parts in reverse order. The connecting rod

should be positioned in the upper dead point when fitting
the diaphragm. Ensure correct positioning of all parts.

➡ Check correct sealing ring seating.
➡ Re-make hose connection and re-tighten direct screw

joint (20).

➡ Test pump for function.

7. Service

Repair orders are carried out according to our
general conditions of sale and supply.

➡ If repairs are necessary, please send the unit together

with a short damage description to your nearest Pfeiffer
Vacuum Service Center.

☞

PLEASE NOTE

Do Make Use Of Our Service Facilities

In the event that repairs are necessary to your pumping
station, a number of options are available to you to ensure
any system down time is kept to a minimum:
–Have the pump repaired on the spot by our Pfeiffer

Vacuum Service Engineers;

–Return the individual components to the manufacturer for

repairs;

– Replace individual components with a new value

exchange units.
Local Pfeiffer Vacuum representatives can provide full
details.

Before Returning:

➡ Dismantle all accessories.
➡ Attach a clearly visible notice: “Free of contamination” (to

the unit being returned, the delivery note and accompany-

ing paperwork).
Harmful substances" are substances and preparations as
defined in current legislation. Pfeiffer Vacuum will carry out
the decontamination and invoice this work to you if you have
not attached this note. This also applies where the operator
does not have the facilities to carry out the decontamination
work. Units which are contaminated microbiologically, explo­sively or radioactively cannot be accepted as a matter of
principle.

Fill Out The Contamination Declaration

➡ In every case the "Contamination Declaration" must be

completed diligently and truthfully.
➡ A copy of the completed declaration must accompany the

unit; any additional copies must be sent to your local

Pfeiffer Vacuum Service Center.
Please get in touch with your local Pfeiffer Vacuum represen­tatives if there are any questions regarding contamination.

Decontaminate units before returning or

possible disposal. Do not return any units which
are microbiologically, explosively or radio­actively contaminated.

Returning Contaminated Units

If contaminated units have to be returned for
maintenance/repair, the following instructions concerning
shipping must be followed without fail:

➡ Neutralise the pump by flushing with nitrogen or dry air.
➡ Seal all openings to the air.
➡ Seal pump or unit in suitable protective foil.
➡ Ship units only in appropriate transport containers.
