VDR-1B-1A1-U-1133K Low Pressure Variable Vane Pump

The VDR-1B-1A1-U-1133K is a compact variable displacement vane pump designed for hydraulic systems requiring low-pressure operation, stable flow regulation and space-saving installation.

Featuring a pressure compensated vane structure, this model automatically adjusts hydraulic output according to system demand, helping reduce unnecessary energy consumption during operation.

The 1A1 configuration is optimized for lower pressure hydraulic circuits, while the U mounting configuration provides flexibility for equipment requiring special installation arrangements.

Compared with higher displacement VDR models, this compact version is suitable for hydraulic systems where controlled flow output and efficient operation are more important than high pressure performance.
