T7ES / T7EL Hydraulic Vane Pump Cartridge Kit
Product Overview
T7ES / T7EL Cartridge Kit is the core wearable internal replacement assembly for Vickers T7ES single‑pump and T7EL double‑pump Hydraulic Vane pump, which is the key consumable component of the complete hydraulic pump. It is widely used for overhaul and performance recovery of industrial hydraulic system and various hydraulic‑driven Machine.
This modular cartridge assembly consists of rotor, pin‑driven vanes, cam ring, side plates and matched sealing parts. It adopts advanced pin‑type vane structure for high‑pressure operation. T7ES applies to single pump unit, while T7EL fits double pump configuration. The cartridge‑in‑housing design enables convenient on‑site maintenance without removing the whole hydraulic pump from the Machine. It effectively restores rated flow and pressure output of the hydraulic system, avoiding high costs of full pump replacement.

Working Principle
As the core pumping unit inside the Hydraulic Vane pump, T7ES / T7EL Cartridge Kit completes oil suction and pressure delivery for the hydraulic pump. Driven by the main shaft, the rotor rotates, and internal pins push vanes tightly against the inner surface of the cam ring. Periodic volume changes between vanes generate oil suction and high‑pressure oil output to supply power for the whole hydraulic system. The pin‑driven vane structure provides reliable vane preload under high‑pressure conditions, maintaining stable performance during long‑time running of the Machine.
When vanes, cam ring or side plates suffer wear, the hydraulic pump will appear internal leakage, pressure drop, insufficient flow and abnormal noise. Installing a brand‑new T7ES / T7EL Cartridge Kit can rapidly restore full working performance of your hydraulic system.
Core Advantages
1. Modular cartridge‑in‑housing construction, no need to disassemble pump housing and pipelines from the Machine, greatly reduces maintenance downtime of the hydraulic system.
2. Pin‑driven vane structure, excellent adaptability for high‑pressure working conditions, improves durability under cyclic heavy‑load operation of industrial Machine.
3. Two variants cover T7ES single pump and T7EL double pump, meets different configuration demands of the hydraulic system.
4. Pre‑matched precision components, retains high volumetric efficiency under long‑term high‑pressure continuous operation.
5. Economical maintenance solution: replace only inner cartridge instead of complete hydraulic pump, effectively lowers spare‑part procurement cost for hydraulic system.
Application Range
T7ES / T7EL Cartridge Kit is an essential wearable spare‑part for T7ES / T7EL high‑pressure Hydraulic Vane pump. It is widely used for repair and overhaul of hydraulic system on injection molding machines, hydraulic presses, metallurgical equipment and other heavy‑duty hydraulic‑driven Machine. Suitable for hydraulic repair workshops, equipment integrators and global spare‑parts distributors.
