Product details

Sumitomo QT23‑5F‑Z Hydraulic Gear Pump

Product Overview

Sumitomo QT23‑5F‑Z Hydraulic Gear Pump is a high‑efficiency fixed‑displacement internal‑mesh Hydraulic gear pump. This premium‑quality hydraulic pump delivers stable low‑noise pressure and flow output for medium‑pressure industrial hydraulic system and medium‑load hydraulic‑driven Machine.

This Hydraulic gear pump adopts advanced internal‑meshing gear structure, featuring low pressure pulsation, smooth operation and long service life. Its compact design is suitable for limited‑space installation conditions. It is widely applied to injection molding machines, hydraulic presses, machine tools and automation equipment, acting as reliable power source for the whole hydraulic system.

Working Principle

As a high‑performance internal‑mesh Hydraulic gear pump, this hydraulic pump relies on meshing rotation of inner and outer gears to complete oil suction and pressure delivery. Driven by input shaft, gears rotate inside the pump housing. The sealed cavity volume changes periodically. Volume expansion draws in hydraulic oil, while volume compression generates high‑pressure oil to supply power for the complete hydraulic system. The optimized internal‑meshing structure greatly reduces vibration and noise during long‑time running of the Machine.

When gear components, side plates or bearings suffer wear, the hydraulic pump will produce internal leakage, pressure drop, insufficient flow and abnormal noise. Timely replacement of wear‑prone parts can restore full working performance of your hydraulic system.

Core Advantages

1. Premium internal‑mesh gear construction, outstanding low‑noise performance, fits noise‑sensitive workshop environment of industrial Machine.

2. High volumetric efficiency under medium‑pressure continuous operation, stable flow and pressure output for complex hydraulic system.

3. Compact overall dimension, saves installation space, ideal for space‑constrained industrial Machine.

4. Standard mounting and port dimensions, good interchangeability for original replacement and existing hydraulic system retrofitting.

5. Robust internal structure, long service life, reduces maintenance frequency of the hydraulic pump.

Application Range

Sumitomo QT23‑5F‑Z Hydraulic gear pump is a high‑performance power‑supply hydraulic pump for industrial hydraulic system. Widely used in injection‑molding machinery, hydraulic presses, precision machine tools, packaging equipment and other hydraulic‑driven industrial Machine. Popular among hydraulic repair workshops, equipment integrators and global spare‑parts distributors.
