Beinlich ZPIR 425/12-10/2-F-A/R Internal Gear Pump
Product Overview
The Beinlich ZPIR series internal gear pump is a hydraulic component designed for low-noise, high-efficiency fluid transfer. This model (ZPIR 425/12-10/2-F-A/R) utilizes an internal gear design to minimize operational noise and enhance volumetric efficiency, making it ideal for noise-sensitive and energy-conscious applications such as hydraulic drives, machine tool coolant circulation, and precision fluid control.
Key Features
Ultra-Low Noise Operation: Internal gear engagement reduces mechanical vibration, eliminating the need for additional sound damping.
High Volumetric Efficiency: Optimized flow path design minimizes internal leakage and improves energy utilization.
Wide Operating Range: Compatible with high-viscosity media (10–1,000 mPa·s) and extreme temperatures (-30°C to +150°C).
High-Pressure Performance: Rated operating pressure up to 120 bar for demanding hydraulic loads.
Compact & Reliable: Robust structure with low maintenance requirements and high contamination resistance.
Technical Specifications
Displacement Range: 1.00–207.00 cm³/rev (typical for medium-to-large flow applications)
Speed: 300–3,000 rpm
Media/Operating Temperature: -20°C to +150°C
Seal Configuration: Multiple flange/shaft seal options (e.g., F-A/R denotes specific seal and rotation direction)
Applications
Low-noise hydraulic system drives
Precision machine tool coolant delivery
Hydraulic press “overrun pump” systems combined with radial piston pumps
