PSV-SNCF-40HRMC-66-110/115

The PSV-SNCF-40HRMC-66-110/115 pump is manufactured by Bosch Rexroth for the PSV Variable Vane Pumps series. Designed for hydraulic automation circuits, it supplies variable oil flow to actuators while adapting to load changes. The pump type is a variable volume vane unit, so displacement adjusts automatically to match demand and limit energy loss. At a drive speed of 1750 rpm it delivers a rated flow of 30 gpm, providing consistent volume for medium-capacity machines. System limits are supported by a 2000 psi rated pressure that allows operation in standard industrial power units. Installation is simplified by flange mounting, and the same flange also carries the side-ported fluid connections to keep hoses aligned with manifold layouts. The shaft is built for right-hand rotation, ensuring compatibility with clockwise prime movers common on electric motor drives.

Pressure regulation features include a two-stage compensator that first reacts to rising outlet pressure and then fine-tunes displacement, so line pressure stays stable during rapid load shifts. A solenoid two pressure control lets an external coil switch the pump between two discrete pressure settings, integrating the unit into programmable hydraulic cycles. Seal rings and gaskets are made of Viton, enabling the housing to tolerate common petroleum fluids and elevated temperatures without leakage. Because volume control is listed as none, all displacement adjustments occur through the internal compensator rather than an auxiliary override. The absence of extra volume control hardware reduces envelope size, making the pump well suited for compact automation skids.
