DP43 Medium‑High Pressure Vane Pump
Product Overview
DP43 Medium‑High Pressure Vane Pump is a fixed‑displacement double Hydraulic Vane pump. This robust hydraulic pump adopts DP4 frame combined with DP3 frame, providing two independent flow outputs for medium‑high pressure industrial hydraulic system and multi‑action automated Machine.
This double Hydraulic Vane pump features balanced vane structure, low pressure pulsation and low‑noise running performance. Two separate pumping chambers can supply oil for different hydraulic circuits simultaneously. It supports replaceable cartridge kit for convenient on‑site overhaul. Widely applied for injection molding machines, hydraulic presses, machine tools and other industrial equipment, it acts as stable power source for the whole hydraulic system.

Working Principle
As a dual‑unit Hydraulic Vane pump, this hydraulic pump contains two independent pumping assemblies inside one housing. Driven by input shaft, rotors and vanes rotate inside respective cam rings. Centrifugal force pushes vanes closely against cam‑ring inner surface. Periodic volume change completes oil suction and high‑pressure oil output, delivering two separate pressure flows for the complete hydraulic system. The balanced‑vane structure offsets radial force, reduces vibration and noise during long‑time running of the Machine.
When vanes, cam ring or side plates become worn, the hydraulic pump will generate internal leakage, pressure drop, insufficient flow and abnormal noise. Installing matched DP series cartridge kit can rapidly restore full working performance of your hydraulic system.
Core Advantages
1. Balanced vane structure, low pressure pulsation and low‑noise performance, suitable for noise‑sensitive production environment of industrial Machine.
2. Dual independent flow output, supplies oil for two separate hydraulic circuits at the same time and optimizes layout of complex hydraulic system.
3. Modular cartridge‑in‑housing design, supports quick field maintenance without removing the whole hydraulic pump from Machine, shortening downtime of hydraulic system.
4. Standard mounting and port dimensions, good interchangeability for original replacement and system retrofitting.
5. Compact double‑pump layout, saves installation space while maintaining high volumetric efficiency under continuous medium‑high‑pressure working conditions.
Application Range
DP43 medium‑high‑pressure double Hydraulic Vane pump is an important dual‑flow power‑supply hydraulic pump for industrial hydraulic system. Widely used in injection‑molding machinery, general hydraulic presses, automation machine tools, packaging equipment and other hydraulic‑driven industrial Machine. Well‑received by hydraulic integrators, repair workshops and global spare‑parts distributors.
