PSV-PNCF-40HRM-66

The PSV-PNCF-40HRM-66 pump is manufactured by Bosch Rexroth and belongs to the PSV Variable Vane Pumps series. It supplies hydraulic power to automated machinery where stable pressure and adaptable flow are required. A pressure compensator governs displacement so outlet flow decreases once circuit pressure reaches its setting, preventing excess energy usage. The unit delivers a rated flow of 30 GPM when the drive shaft turns at its flow rating basis of 1750 RPM, giving designers a clear reference for sizing actuators. System safety is supported by a 2000 PSI pressure rating that defines the maximum continuous working pressure. Right hand rotation matches clockwise drive arrangements on standard electric motors, simplifying coupling selection. Viton seals resist common hydraulic oils and elevated temperatures, extending service life in continuous-duty applications.

Flange mounted construction lets the PSV-PNCF-40HRM-66 fasten directly to a motor or bracket, keeping the shaft and housing aligned during load changes and reducing vibration. Hydraulic lines attach through flange connections that provide large sealing faces for secure joints, and the side-ported arrangement routes hoses parallel to the case so the assembly occupies minimal depth. These flange ports accept standard code fittings, which simplifies hose selection and maintenance. The pumping element follows a variable volume vane design, allowing the cam ring to shift automatically with pressure demand. External displacement adjustment is omitted because volume control is none, reducing component count and removing the need for manual setting changes.
