Technical Specifications:
The EIPS 2 internal gear pump is designed with a constant displacement volume, available in rated sizes NG 005 to 025. The specific volume ranges from 5.4 to 25.2 cm³/rev. It operates continuously at a pressure of 250 bar, with peak pressures up to 350 bar for short durations. The pump supports a maximum speed of 4,200 min^-1 and operates efficiently within a viscosity range of 10 to 300 mm²/s and temperatures from -20°C to +100°C. The pump is compatible with HL – HLP DIN 51 524 Teil 1/2 operating mediums.

Design and Features:
The pump features axial and radial gap compensation, a pressure cover, and is suitable for mobile and industrial hydraulic systems. It is noted for low noise, long life, and low pulsation. The pump's efficiency ranges from 91% to 95% volumetric and 90% to 93% hydraulic-mechanical.

Dimensions and Installation:
The pump dimensions vary by rated size, with specific measurements provided for NG 005 to 025. Installation requires M8 DIN 912 screws with a tightening torque of 25±5 Nm. Various configurations are available, including pumps with Oldham coupling, SAE-A-2-hole flange, and cylindrical shafts.

Flange Connections:
The document details flange connections, including 90° and straight 24° DIN 3901 types, with specifications for bolt sizes, O-rings, and maximum pressure ratings.

Performance Characteristics:
The pump's performance is characterized by its volumetric flow, efficiency, and sound pressure levels, measured under specific conditions. The data provided serves as a product description and is subject to change.
