High Pressure Internal Gear Pumps EIPR 1

Product catalog summary

Technical Specifications:
The EIPR 1 internal gear pump is available in four nominal sizes: NG 015, 022, 032, and 040, with specific volumes ranging from 1.5 to 4.0 cm³/U. The continuous operating pressure is 200 bar for NG 015 and 180 bar for other sizes, with a peak operating pressure of up to 250 bar for short durations. The maximum rotational speed is 4,500 min^-1 for NG 015 and 3,600 min^-1 for others. Operating viscosity ranges from 10 to 300 mm²/s, with a start viscosity of 2,000 mm²/s. The operating temperature ranges from -20°C to +100°C, with medium temperatures between -20°C and +80°C.

Features:
The pump features axial and radial gap compensation, a radial compensation ring pump system, and is suitable for mobile and industrial hydraulics. It offers direct mounting, low noise, long service life, and low pulsation (~2% pressure pulsation).

Performance Data:
The volumetric efficiency ranges from 88% to 90%, and the hydraulic-mechanical efficiency is between 86% and 87%. Noise levels are measured between 53 dB[A] and 58 dB[A] under specified conditions.

Ordering Information:
The pump can be ordered with different configurations, including right or left rotation, cylindrical or two-flat shaft ends, and various connection types. An example order code is EIPR1-032 RA 31-10, indicating a ring pump with a 3.2 cm³/U displacement, right rotation, cylindrical shaft, and direct mounting.

Installation and Maintenance:
The pump requires M8 DIN 912 mounting screws with a torque of 25±5 Nm. It is designed for a contamination level of NAS 1638, Class 9, with a filter rating of β10 ≥ 100.
