CP31 Medium‑Pressure Vane Pump
Product Overview
CP31 Medium‑Pressure Vane Pump is a fixed‑displacement double Hydraulic Vane pump. This reliable hydraulic pump adopts CP3 combined with CP1 pump sections, delivering two independent flow outputs for medium‑pressure industrial hydraulic system and multi‑action hydraulic‑driven Machine.
This double Hydraulic Vane pump applies proven balanced vane structure to achieve low pressure pulsation and smooth running performance. Two separate pumping chambers can supply hydraulic oil for different circuits within one hydraulic system at the same time. It supports interchangeable CP3 and CP1 cartridge kits for convenient on‑site maintenance without full pump disassembly. It is widely fitted to medium‑size machine tools, packaging machinery and light‑medium hydraulic equipment, serving as stable power source for industrial Machine.

Working Principle
As a dual‑unit Hydraulic Vane pump, this hydraulic pump integrates two independent pumping assemblies inside one pump housing driven by a common shaft. Driven by input shaft, rotors and vanes rotate inside respective cam rings. Centrifugal force pushes vanes tightly against inner surface of cam rings. Periodic volume variation completes oil suction and pressure oil delivery, providing two separate pressure flows for the whole hydraulic system. The balanced‑vane structure counteracts radial hydraulic force, reducing vibration and noise during long‑time running of the Machine.
When vanes, cam ring or side plates suffer wear, the hydraulic pump will produce internal leakage, pressure drop, insufficient flow and abnormal noise. Replacing matched CP series cartridge kits can rapidly restore full working performance of your hydraulic system.
Core Advantages
1. Balanced vane structure reduces pressure pulsation and vibration, delivering steady flow‑pressure output for light‑medium‑load industrial Machine.
2. Dual independent flow output supplies oil for two different hydraulic circuits simultaneously, optimizing layout of complex hydraulic system.
3. Modular cartridge‑in‑housing design supports quick field overhaul. There is no need to remove the whole hydraulic pump from the Machine, effectively cutting downtime of the hydraulic system.
4. Standard mounting and port dimensions, excellent interchangeability for original replacement and existing hydraulic system retrofitting.
5. Compact double‑pump configuration, saves installation space while maintaining high volumetric efficiency under continuous medium‑pressure working conditions.
Application Range
CP31 medium‑pressure double Hydraulic Vane pump is an important dual‑flow power‑supply hydraulic pump for industrial hydraulic system. Widely applied in machine tools, packaging machinery, light‑duty hydraulic presses, automation auxiliary equipment and other hydraulic‑driven industrial Machine. Well‑received by hydraulic repair workshops, equipment integrators and global spare‑parts distributors.
