43V High‑Performance Vane Pump
Product Overview
43V High‑Performance Vane Pump is a fixed‑displacement double Hydraulic Vane pump. This heavy‑duty hydraulic pump adopts 4‑frame plus 3‑frame combined structure, providing two independent flow outputs for medium‑high pressure industrial hydraulic system and multi‑action hydraulic‑driven Machine.
This double Hydraulic Vane pump utilizes classic balanced vane design to minimize pressure pulsation and operating noise. Two separate pumping chambers can deliver hydraulic oil to different circuits of one hydraulic system simultaneously. It supports interchangeable cartridge kit for fast field maintenance. It is widely adopted in injection molding machines, hydraulic presses and metallurgical equipment, acting as reliable power source for heavy‑duty Machine.

Working Principle
As a dual‑unit Hydraulic Vane pump, this hydraulic pump contains two independent pumping assemblies inside one pump housing. Driven by input shaft, rotors and vanes rotate inside their respective cam rings. Centrifugal force pushes vanes closely against inner surface of cam rings. Cyclic volume variation realizes oil suction and high‑pressure oil delivery, supplying two separate pressure flows for the whole hydraulic system. The balanced‑vane structure counteracts radial hydraulic force, lowering vibration and noise during long‑time running of the Machine.
Once vanes, cam ring or side plates get worn, the hydraulic pump will suffer internal leakage, pressure drop, insufficient flow and abnormal noise. Replacing the matching 43V cartridge kit can rapidly restore complete performance of your hydraulic system.
Core Advantages
1. Mature balanced vane structure, reduces pressure pulsation and vibration, delivers stable pressure and flow output for heavy‑load industrial Machine.
2. Dual independent flow output, feeds oil to two separate hydraulic circuits at the same time, optimizes layout of complex hydraulic system.
3. Modular cartridge‑in‑housing design, supports quick on‑site overhaul without removing the whole hydraulic pump from the Machine, effectively cuts downtime of hydraulic system.
4. Standard SAE mounting and port dimensions, great 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‑high‑pressure working conditions.
Application Range
43V High‑Performance double Hydraulic Vane pump is a vital dual‑flow power‑supply hydraulic pump for industrial hydraulic system. Widely used for injection‑molding machinery, heavy‑duty hydraulic presses, metallurgical auxiliary equipment, machine tools and other hydraulic‑driven industrial Machine. Popular among hydraulic integrators, repair workshops and global spare‑parts distributors.
