ZPI Internal gear pumps

Product catalog summary

Specifications:
The document outlines the specifications for ZPI internal gear pumps, detailing displacement volumes for different models (ZPI 1 to ZPI 4), ranging from 1.00 to 207.00 cc/rev. The pumps can operate in both counterclockwise and clockwise directions. Suction and pressure ports vary by model, with ZPI 1-2 using threaded ports and ZPI 3-4 using threaded ports/SAE flanges. The gear type is internal spur gears, and the operational speed ranges from 300 to 3,000 rpm, considering pressure and viscosity conditions. Viscosity range is 10 to 1,000 mPa·s, with ambient temperatures from -30°C to +60°C and fluid temperatures from -20°C to +150°C.

Operating Conditions:
The operating pressure refers to permissible permanent and peak pressures, with standard values provided. For extreme conditions involving low viscosity, low speed, and high pressure, consultation with Beinlich is advised. Special designs are available for non-standard temperature conditions.

Advantages:
ZPI internal gear pumps offer low pulsation, low-noise operation, long service life, and high volumetric efficiency.

Typical Applications:
These pumps are suitable for low-noise hydraulic drives, coolant pumps for machine tools, and "overdrive pumps" for hydraulic presses, especially when combined with Beinlich Radial Piston Pumps.

Certifications:
The document mentions certifications including ISO 9001, ISO 14001, and ISO 45001, indicating compliance with quality, environmental, and occupational health and safety standards.
