SQP32 Low‑Noise Vane Pump
Product Overview
SQP32 is a fixed‑displacement double Hydraulic Vane pump, a compact low‑noise hydraulic pump featuring dual‑flow output for medium‑pressure industrial hydraulic system and multi‑functional automated Machine.
This double Hydraulic Vane pump adopts classic 12‑vane balanced vane construction to lower pressure pulsation and operating noise. Combined by SQP3 frame and SQP2 frame, two independent pump chambers provide separate oil flow to satisfy different circuit requirements within one hydraulic system. It supports maintenance with SQP Series Cartridge Kit, allowing fast on‑site overhaul. It is widely selected as power source for injection auxiliary equipment, machine tools, small hydraulic presses and other industrial Machine.

Working Principle
As a dual‑unit Hydraulic Vane pump, this hydraulic pump contains two independent pumping assemblies inside one pump housing. Driven by the input shaft, rotors and vanes revolve inside each cam ring. Centrifugal force presses vanes tightly against the inner cam‑ring surface. Cyclic volume variation achieves oil suction and pressure delivery, supplying two independent pressure oil flows for the complete hydraulic system. The balanced‑vane structure reduces radial force and pressure ripple to realize quiet operation of the Machine.
Wear of vanes, cam ring or side plates will cause internal leakage, pressure drop, flow reduction and abnormal noise of the hydraulic pump. Installing matched SQP Series Cartridge Kit can quickly recover full performance of your hydraulic system.
Core Advantages
1. Optimized 12‑vane balanced‑vane design, effectively suppresses running noise, fits noise‑controlled production environment of industrial Machine.
2. Dual independent flow output, supplies oil for two separate hydraulic circuits simultaneously and simplifies the layout of complex hydraulic system.
3. Modular SQP Series Cartridge Kit design, supports convenient maintenance without removing the whole pump from Machine, shortening downtime of the hydraulic system.
4. Standard SAE mounting and port dimensions, good interchangeability for original replacement and retrofitting existing hydraulic system.
5. Compact double‑pump structure, saves installation space while maintaining high volumetric efficiency under long‑time continuous operation of industrial Machine.
Application Range
SQP32 low‑noise double Hydraulic Vane pump serves as essential dual‑flow power‑supply hydraulic pump for medium‑pressure industrial hydraulic system. It is widely used for injection‑molding auxiliary machinery, general‑purpose hydraulic presses, automation machine tools, packaging equipment and other hydraulic‑driven industrial Machine. Popular among hydraulic integrators, equipment manufacturers and global spare‑parts distributors.
