• The medium moves continuously and without
noticeable pulsation toward the pump discharge.

• Proper clockwise rotation must be ensured at all
times. Incorrect counterclockwise rotation will re­sult in dry running and pump damage. Cata­strophic failure is possible!

• Screw pumps are self-priming, however, dry
running must be avoided under any circumstances
as it will almost instantly damage the pump and it
might result in catastrophic failure.

• Screw pumps are positive displacement pumps
and must therefore always be used in combination
with a pressure limiting valve or pressure relief
valve.

2.1 Scope

Pumping of fluids at high backpressure. The dis­charge pressure needs to be at least 2 bar higher
than the inlet pressure.

2.2 Application range

• Screw pumps are designed for pumping filtered,
lubricating fluids (Please consult with the manu­facturer for specific applications).

• Screw pumps are used in applications where high
pressures and constant flow rates are required
(e.g. general machine design, machine tool indus­try, etc.)

Operate pump within the design limititations and in
accordance with section 2.6.

2.3 Working principle

• The intermeshing threads of three screw spindles
generate liquid holding chambers.

• The center spindle is driven and all three screw
spindles rotate.

ATTENTION

If high pressure screw pumps are to be used
outside of the recommended ranges, a suitable
filter system (e.g. filter bags) must be installed
upstream from the pump or pumps with special
features must be used (e.g., with coated spin­dles).

If pump failure is caused by excessive wear due
to foreign particles, the warranty is void!

In applications where hard or abrasive particles
are present, the use of coated spindles is highly
recommended.

3 Safety instructions

When operating the pump, the safety instructions
contained in this manual, the relevant national acci­dent prevention regulations and any other service
and safety instructions issued by the plant operator
are to be observed.

3.1 Hazards in the event of non-compliance with
the safety instructions

Non-compliance with the safety instructions may
produce a risk to the personnel as well as to the
environment and the machine and results in a loss of
any right to claim damages. For example, non­compliance may involve the following hazards:

• Failure of important functions of the ma-

chines/plant

• Failure of specified procedures of maintenance

and repair

• Exposure of people to electrical, mechanical and

chemical hazards

• Endangering the environment due to hazardous

substances being released

3.2 Unauthorized modes of operation

3.5 Safety instructions relevant for operation

• If hot or cold machine components involve haz­ards, they must be guarded against accidental
contact.

• Guards for moving parts (e.g. coupling) must not
be removed from the machine while in operation.

• Never subsequently alter any safety devices (e.g.
pressure relief valves)!

• It is necessary to ensure that all safety devices
always work properly!

• Any leakage of hazardous (e.g. explosive, toxic,
hot) fluids (e.g. from the shaft seal) must be
drained away so as to prevent any risk to per-sons
or the environment. Statutory regulations are to be
complied with.

• Hazards resulting from electricity are to be pre­vented (see for example, the VDE Specifications
and the bye-laws of the local power supply utili­ties).

• The pumps’ stability against falling over is not
ensured unless it is properly mounted onto the
tank or to the floor.

• The female threads on the motor MUST NOT be
used to lift the entire pump and motor assembly.

• Pump may not be used in potentially explosive
environments!

• Pump and discharge piping are not designed to
hold any weight and may not be used as a step
ladder.

3.3 Remaining Risk

Risk of Injury!

Risk of squeezing or crushing body parts when
installing or removing the pump exists. Proper and
secured lifting tools must be used.

Risk of burns!

The pump must have cooled down sufficiently prior to
commencing any repair, maintenance or installation.

3.4 Qualification and training of operating per-

sonnel

The personnel responsible for operation, mainten­ance, inspection and assembly must be adequately
qualified. Scope of responsibility and supervision of
the personnel must be exactly defined by the plant
operator. If the staff does not have the necessary
knowledge, they must be trained and instructed,
which may be performed by the machine manufac­turer or supplier on behalf of the plant operator.
Moreover, the plant operator is to make sure that the
contents of the operating manual are fully understood
by the personnel.

3.6 Safety instructions relevant for mainten­ance, inspection and assembly work

Any work on the machine shall only be performed
when it is at a standstill, it being imperative that the
procedure for shutting down the machine described in
this manual be followed.
Pumps and pump units which convey hazardous
media must be decontaminated.
On completion of work all safety and protective
facilities must be re-installed and made operative
again.
Prior to restarting the machine, the instructions listed
under “Start up” are to be observed.

3.7 Signs on the pump

spare parts

Any modification may be made to the machine only
after consultation with the manufacturer. Using spare
parts and accessories authorized by the manufactur­er is in the interest of safety. Use of other parts may
exempt the manufacturer from any liability.

4 Transport and Temporary Storage

Protect pumps against damage during transportation.
The pumps may only be transported lying flat and
must be secured on the motor side as well as on the
pump side.
Store pumps protected from moisture in an enclosed
location. Prevent foreign bodies from entering the
pump.
Keep the storage temperature above freezing

Pumps are factory preserved.
If storage exceeds 6 months, the preservation should

be checked and reapplied if applicable.
Pumps that have been immersed or have been

running must be cleaned and preserved prior to
storage. This applies especially to water based fluids!

4.1 Pump Preservation

4.1.1 Draining pump

Pumps with mechanical seal –G or axial thrust

–A:

6. Place pump on a work bench (7) horizontally

with the threaded port facing up. The flange (8)
may not touch the surface. See picture 1.

7. Plug outlet port (5) with a sealing plastic cap.

8. Turn the motor shaft as quickly as possible

counterclockwise. This will allow for the re­maining fluid to drain from the adjacent cavities
(6).

9. Repeat steps 1-8 until no more fluid drains.

4.1.2 Pump preservation

Interior Preservation

1. Outlet (5) and inlet port (3) should be open.

2. Place pump on a work bench (7) horizontally

with the threaded port facing up. The flange (8)
may not touch the surface.

3. Pour preservation agent (spray oil) into the inlet

port (3) and turn motor (1) shaft clockwise until
it becomes visible at the outlet port and the fluid
level of the oil is above the lowest point of the
labyrinth seal area.

Pumps with mechanical seal –G or axial thrust
–A:

4. Plug outlet port (5) with a sealing plastic cap.

5. Turn motor shaft (1) clockwise as quickly as

possible by hand in order for the preservation
agent to enter into the adjacent cavities (6).

1. Separate pump and motor.

2. Clean the pump body thoroughly

3. Outlet (5) and Inlet port should be open.

4. Stand pump up with the coupling (2) facing up
tilting it in direction of the inlet port (3).

5. Turn motor shaft (1) counterclockwise. Keep
pump tilted until it is completely drained.

Exterior Preservation

6. Preserve all unpainted metal components
