High Pressure Internal Gear Pumps EIPS 3

Product catalog summary
Overview: The document provides detailed technical specifications and operational guidelines for the EIPS 3 internal gear pump, designed for use in mobile and industrial hydraulic systems. It highlights the pump's features, technical data, dimensions, ordering codes, and commissioning instructions.
Specifications: The EIPS 3 pump features axial and radial gap compensation, a pressure cover, and is suitable for mobile hydraulic systems like forklifts. It offers low pulsation (~2%) and long life. The pump is available in various rated sizes (NG 020 to 050) with specific volume capacities ranging from 20.0 to 50.3 cm³/rev. It operates at continuous pressures up to 250 bar and peak pressures up to 350 bar, with a maximum speed of 3,600 min⁻¹.
Technical Data: The pump operates within a temperature range of -20°C to +100°C and supports operating viscosities between 10 to 300 mm²/s. It is compatible with HL-HLP DIN 51 524 part 1/2 hydraulic oils. The pump's efficiency is high, with volumetric efficiency (ηvol) up to 95% and hydraulic-mechanical efficiency (ηhm) up to 93%.
Dimensions and Ordering: Detailed dimensions for each rated size are provided, along with ordering codes for different configurations, including shaft types and flange connections. The document specifies the use of M10 DIN 912 fastening screws with a tightening torque of 49±5 Nm.
Commissioning Instructions: Key steps include ensuring correct mounting, using filtered pressure fluid, and observing the correct rotation direction. The pump should be started in no-load operation to ensure lubrication, and it must not run without oil. Venting procedures are outlined to remove air bubbles from the system.
Operational Guidelines: The document emphasizes the importance of using brand-name hydraulic oils and avoiding mixing different oil types. It advises on maintaining the fluid tank, ensuring proper pipe routing, and using appropriate filters. Safety precautions include depressurizing the system before maintenance and ensuring all safety gear is in place.
Important Remarks: Modifications to the pump void warranty, and repairs should only be conducted by authorized personnel. The document stresses the importance of adhering to specified ratings and maintaining the pump in flawless condition.

- Check whether the unit has been carefullyand correctly mounted.- Fill with pressure fluid only using a filter withthe required minimum retention rate.- Observe the arrow indicating the correct sense of rotation.- Start up the pump in no-load operation andrun without pressure for a few seconds to ensure sufficient lubrication.- Never allow the pump to run without oil. - The pump has to be bleed before building uppressure against a valve. Wear is covered by running dry.- If the pumped oil still contains bubbles of airafter appr. 20 seconds, investigate the cause.Once the target operating values...

Drive system Fluid tank Pressure fluid > Electric motor + pump mount + coupling +pump- No radial or axial forces may be permitted toact on the pump drive shaft.- The motor and pump must be precisely aligned. - Always use a coupling which will permitcompensation for any shaft displacement.- When mounting the coupling, avoid applyingaxial force, i.e. never attempt to press or knock into place using a hammer or similar instrument. - Adjust the useful volume of the tank to theoperating conditions.- Never exceed the admissible fluid temper-ature. If necessary, provide a cooler. - We recommend using...
