SQP Series Cartridge Kit
Product Overview
SQP Series Cartridge Kit is the core wearable internal replacement assembly for Tokimec SQP low‑noise double Hydraulic Vane pump, serving as key consumable components of the whole hydraulic pump. It is widely used for overhaul and performance recovery of industrial hydraulic system and various hydraulic‑driven Machine.
This modular cartridge assembly includes rotor, vanes, cam ring, side pressure plates and matching sealing parts. Designed for SQP series double vane pump, including SQP43, SQP42, SQP41, SQP32, SQP31, SQP21 models. Adopting 12‑vane low‑noise structure, it can realize on‑site maintenance without removing the entire pump body from the Machine. Effectively restores rated flow and pressure output of the hydraulic system, avoiding the cost of replacing the whole hydraulic pump.

Working Principle
As the core pumping unit inside the Hydraulic Vane pump, SQP Series Cartridge Kit completes oil suction and pressure delivery for the hydraulic pump. Driven by main shaft, rotor and vanes rotate inside cam ring. Centrifugal force pushes vanes closely against cam‑ring inner surface. Periodic volume change between vanes generates oil suction and high‑pressure oil output to supply power for the whole hydraulic system. The balanced‑vane structure offsets radial hydraulic force, reducing bearing load and realizing low‑noise operation 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. Installing brand‑new SQP Series Cartridge Kit can rapidly restore full working performance of your hydraulic system.
Core Advantages
1. Modular cartridge‑in‑body design, no need to disassemble pump housing and pipeline from the Machine, greatly shortens maintenance downtime of hydraulic system.
2. 12‑vane balanced‑vane internal structure, effectively reduces running noise, suitable for noise‑sensitive workshop environment of industrial Machine.
3. Full compatibility for multiple SQP double‑pump combinations, covers mainstream SQP43, SQP42, SQP41, SQP32, SQP31, SQP21 models to meet diverse hydraulic system requirements.
4. Pre‑matched high‑precision components, maintains high volumetric efficiency under long‑term continuous pressure working condition.
5. Cost‑effective maintenance solution: replace only inner cartridge instead of complete hydraulic pump, lower spare‑part procurement cost for hydraulic system.
Application Range
SQP Series Cartridge Kit is vital wearable spare‑part for SQP series double Hydraulic Vane pump. It is widely applied for repair and overhaul of hydraulic system on injection molding machines, machine tools, hydraulic presses, packaging machinery and other industrial hydraulic‑driven Machine. Popular for hydraulic repair workshops, equipment integrators and global spare‑parts distributors.
