PV6000 Series Variable Delivery Pumps


35.4 to 54.0 gpm (134,0 to 204,4 L/min) at 1800 rpm
Rated: 5 500 psi (380 bar), Maximum: 6 000 psi (420 bar)

  • Hydraulically controlled variable delivery.
  • Contamination tolerant, for operation in dirty environments.
  • Bi-directional rotation providing constant flow direction regardless of drive shaft rotation.
  • A wide range of fluid compatibility, for reliable operation with low-lubricity, low viscosity fluids.
  • Shaft Options: Standard keyed, Optional spline.
  • Seal Options: Standard Nitrile. Optional Fluorocarbon, or EPR seals for use with some phosphate ester fluids.
  • Split-Flow® models can supply two independent flows (from five pistons each). These pumps can supply two variable flows, or one fixed and one variable flow.
  • Tandem pump model available.

Pump Selection Notes

  1. Please contact the Dynex sales department for a complete model code to order these pumps.
  2. Output flows are based on typical performance at rated pressure with pressurized inlet where required. PV4000 Series pumps with ports for standard S.A.E. fittings are not recommended for operation above 8000 psi (560 bar). Contact the fitting manufacturer for the pressure rating of the fitting.
  3. These models are for clockwise rotation (viewed from shaft end).
