• 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.

ciple
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.

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
It is imperative that signs affixed to the machine, e.g.
• arrow indicating the direction of rotation
• symbols indicating fluid connections

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 Drain excess preserving agent and plug outlet and
inlet ports with plastic caps. Collect draining coolant and oil and dispose in ac-
cordance with applicable local laws and regulations!
