CP42 Medium‑Pressure Vane Pump
Product Overview
CP42 Medium‑Pressure Vane Pump is a fixed‑displacement double Hydraulic Vane pump. This robust hydraulic pump adopts CP4 combined with CP2 pump sections, delivering two independent flow outputs for medium‑pressure industrial hydraulic system and multi‑action hydraulic‑driven Machine.
This double Hydraulic Vane pump adopts mature balanced vane structure to realize low pressure pulsation and smooth operation. Two separate pumping chambers can supply hydraulic oil to different circuits within one hydraulic system at the same time. It supports interchangeable CP4 and CP2 cartridge kits for convenient on‑site maintenance without full pump disassembly. It is widely applied to medium‑size machine tools, packaging machinery and light‑to‑medium‑duty hydraulic equipment, serving as stable power source for industrial Machine.

Working Principle
As a dual‑unit Hydraulic Vane pump, this hydraulic pump contains two independent pumping assemblies inside a single pump housing driven by a shared 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. Optimized balanced vane structure reduces pressure pulsation and vibration, delivers steady flow‑pressure output for light‑medium‑load industrial Machine.
2. Dual independent flow output supplies oil for two different hydraulic circuits simultaneously, simplifies 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 cuts downtime of the hydraulic system.
4. Standard mounting and port dimensions, good 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
CP42 medium‑pressure double Hydraulic Vane pump is a vital dual‑flow power‑supply hydraulic pump for industrial hydraulic system. Widely used in machine tools, packaging machinery, light‑duty hydraulic presses, automation auxiliary equipment and other hydraulic‑driven industrial Machine. Popular among hydraulic repair workshops, equipment integrators and global spare‑parts distributors.
