Gear oil pump QX Series QX51-125/41-040/43-032R

Product Description

Gear oil pump QX Series QX51-125/41-040/43-032R – Hengmeisi's three-in-one BUCHER replacement pump. Integrates three different-displacement pump cores in one housing, delivering three independent output circuits. Rated 310 bar continuous / 370 bar peak, low pulsation, high efficiency, stable long-term operation – ideal for multi-loop hydraulic systems.

Product Advantages

1. Three-Core Integrated Multi-Circuit Design

This triple gear pump adopts an integrated three-pump-core structure, combining QX51 large displacement, QX41 medium displacement and QX43 small displacement pump units. It can provide three independent hydraulic power sources at the same time, replacing three separate single pumps. It greatly saves installation space, simplifies pipeline layout and reduces equipment assembly and maintenance costs.

2. Differentiated Displacement & Flexible Matching

Equipped with 125cc, 40cc and 32cc three-level professional displacements, the pump can independently supply oil for different functional modules of hydraulic equipment such as main power, auxiliary action and control loop. It realizes targeted flow distribution, avoids energy waste caused by single fixed flow, and improves the overall operating efficiency of the hydraulic system.

3. High-Strength Integral Casting & Stable Operation

The overall pump body adopts high-rigidity integral cast iron molding, with strong compression resistance and vibration resistance. The precision forged alloy steel gear set and high-precision bearings ensure low wear and low noise operation under long-term multi-load alternating working conditions. The overall failure rate is far lower than that of assembled multi-pump combination structures.

4. Excellent Anti-Fatigue & Anti-Pollution Performance

Adopting optimized internal meshing tooth profile technology, the pump has small internal friction and strong oil contamination tolerance. It can adapt to complex and harsh industrial working conditions, effectively avoid gear jamming and oil circuit blockage caused by tiny impurities in hydraulic oil, and maintain stable output of each independent loop for a long time.

Model Code

QX51-125/41-040/43-032R follows the standard BUCHER triple pump coding rules, with clear and professional parameter definitions:

QX51-125: QX51 series large-displacement pump core, single displacement 125cm³/rev, used for main high-flow power supply;

QX41-040: QX41 series medium-displacement pump core, single displacement 40cm³/rev, for auxiliary hydraulic circuit power supply;

QX43-032: QX43 series small-displacement pump core, single displacement 32cm³/rev, for precision control loop oil supply;

R: Right-hand drive shaft, standard universal rotation, compatible with most mainstream industrial host equipment.

This three-stage mixed-displacement combined pump is a customized model for complex multi-loop hydraulic systems, widely used in high-end industrial machinery and complete hydraulic equipment supporting.

Product Structure

1. Triple Independent Pump Core Integration Structure

The product integrates three independent internal and external gear sets of different specifications inside one integral pump body. Each pump core is equipped with an independent oil inlet and outlet flow channel, which does not interfere with each other and realizes completely independent three-circuit hydraulic output.

2. Graded Fixed Flow Output Mechanism

Three pump cores with different displacements operate independently with fixed flow respectively. Each loop outputs stable and accurate flow pressure without additional variable control components, which simplifies the design of complex multi-loop hydraulic control system.

3. High-Grade Matching Component Materials

All gear sets are made of high-strength carburized alloy steel, which is precisely ground to ensure high hardness and wear resistance; the overall cast iron pump body has strong pressure resistance and deformation resistance; the supporting high-precision bearings ensure stable operation at a maximum speed of 1600rpm.

4. Integrated Standard Oil Port Layout

Each independent oil circuit is equipped with factory pre-installed standard oil ports and matching sealing structures. The interface is universal and standardized, which is convenient for on-site rapid piping installation and later daily maintenance and replacement of accessories.
