SQP43 Low‑Noise Vane Pump
Product Overview
SQP43 is a fixed‑displacement double‑pump Hydraulic Vane pump, a high‑performance low‑noise hydraulic pump developed by Tokimec, designed to provide dual independent flow outputs for complex industrial hydraulic system and multi‑action automated Machine.
This double Hydraulic Vane pump adopts advanced 12‑vane balanced‑vane structure with pulse‑damping design, greatly suppressing pressure pulsation and running noise. Two independent pump chambers deliver separate oil flow, which can supply power for different hydraulic circuits simultaneously. Equipped with replaceable SQP Series Cartridge Kit, it supports convenient on‑site maintenance. It is widely used for injection molding machines, die‑casting equipment and machine‑tool hydraulic system, serving as stable power source for various industrial Machine.

Working Principle
As a double‑unit Hydraulic Vane pump, this hydraulic pump contains two sets of independent pumping assemblies inside one housing. Driven by input shaft, rotors and vanes rotate inside respective cam rings. Centrifugal force pushes vanes against cam‑ring inner surface. Periodic volume change completes oil suction and pressure delivery, providing two separate pressure oil outputs for the whole hydraulic system. The pulse‑damping structure reduces pressure fluctuation to achieve low‑noise running of the Machine.
When internal components including vanes, cam ring and side plates wear, the hydraulic pump will suffer internal leakage, pressure loss, flow decline and abnormal noise. Replacing matched SQP Series Cartridge Kit can rapidly restore full performance of the hydraulic system.
Core Advantages
1. Low‑noise optimized 12‑vane balanced‑vane structure, effectively reduces pressure pulsation, suitable for noise‑sensitive workshop environment of industrial Machine.
2. Dual independent flow output, can supply oil for two different hydraulic circuits at the same time, simplifies layout of complex hydraulic system.
3. Modular SQP Series Cartridge Kit, supports quick maintenance without removing the whole pump from Machine, shortens downtime of hydraulic system.
4. Standard SAE mounting and port dimensions, good interchangeability for original replacement and system retrofitting.
5. High volumetric efficiency under long‑term continuous working condition, stable pressure output for multi‑action industrial Machine.
Application Range
SQP43 low‑noise double Hydraulic Vane pump is a critical dual‑flow power‑supply hydraulic pump for medium‑high‑pressure industrial hydraulic system. It is widely applied to injection‑molding machines, die‑casting machinery, hydraulic presses, automated machine tools and other multi‑action hydraulic‑driven Machine. Well‑received by hydraulic system integrators, equipment manufacturers and global spare‑parts distributors.
