Gear oil pump QX Series QX51-100/43-020/23-008R

Product Description

China factory direct..Gear oil pump QX Series QX51-100/43-020/23-008R: Hengmeisi triple graded pump. Three isolated cores (large-flow, high-pressure, micro-flow) enable fast feeding, load driving & precise pressure holding. ≤1.4% pulsation. Eliminates slow response, poor precision & energy waste in variable-load conditions.

Product Advantages

1. Three-Gradient Hydraulic Matching, One Machine for Multiple Purposes

This triple pump adopts a unique three-level parameter matching mode that no other conventional pump has. The 100ml/r large-flow circuit realizes high-speed no-load travel to boost equipment efficiency; the 20ml/r medium-flow circuit undertakes stable heavy-load driving operation; the 8ml/r micro-flow ultra-high pressure circuit completes precise clamping, pressure maintaining and fine tuning. It automatically switches working modes according to equipment load changes, realizing seamless integration of high efficiency, heavy load and high precision, which cannot be achieved by single pump and equal-displacement combined pumps.

2. Zonal Independent Energy-Saving Unloading System

Each stage of the pump is equipped with an independent built-in unloading and pressure stabilizing channel. When a single circuit operates independently, the idle two circuits automatically unload and release pressure without idle power consumption and hydraulic oil heating. Compared with traditional multi-pump combined systems, it effectively reduces overall system energy consumption, avoids continuous high-pressure impact on the pump body, and greatly extends the service life of hydraulic accessories and the whole machine.

3. Targeted Graded Wear-Resistant Configuration

Aiming at the different pressure bearing requirements of the three circuits, differentiated accessory configurations are adopted for targeted optimization. The large-flow cavity adopts high-efficiency anti-wear assembly suitable for long-cycle liquid flow; the high-pressure cavity is equipped with thickened bimetallic wear-resistant plates and precision grinding gear pairs; the ultra-high pressure micro-flow cavity is upgraded with imported high-pressure resistant fluororubber seals and anti-fatigue bearings. The whole pump stably withstands 330bar peak pressure, with strong anti-pollution and anti-impact performance adapting to complex working conditions.

4. Highly Integrated Coaxial Structure, Low Failure Rate

Integrated coaxial three-cavity integral casting structure replaces the cumbersome assembly of multiple split pumps and external valve groups. The single-shaft synchronous drive design reduces intermediate transmission links and mechanical failure points. The integrated body effectively saves installation space, reduces pipeline interfaces and leakage risks, and simplifies the overall hydraulic system layout and daily maintenance work.

Model Code

The coding rule of QX51-100/43-020/23-008R is hierarchical and clear, helping global customers quickly identify core parameters and configuration attributes:

- QX51-100: First-stage medium-pressure large-flow pump, displacement 100ml/r, used for equipment rapid feeding and idle fast return;

- QX43-020: Second-stage high-pressure standard pump, displacement 20ml/r, responsible for equipment main load driving and heavy-duty operation;

- QX23-008: Third-stage ultra-high pressure micro-flow pump, displacement 8ml/r, specially used for precise pressure maintaining, clamping and fine action control;

- R: Clockwise rotation; counterclockwise (L) can be customized according to customer installation requirements.

QX51-100/43-020/23-008R is a high-end customized gradient triple pump in the QX series, specially developed for complex equipment integrating high efficiency, heavy load and high precision.

Product Structure

1. Coaxial Three-Cavity Integral Casting Body

Adopts one-piece integral casting molding process, with three independent closed pump cavities arranged in series coaxially. A single drive shaft synchronously drives three groups of gear assemblies with different specifications, realizing synchronous and independent three-channel hydraulic output. The overall structure is compact and rigid, avoiding deformation and vibration of split combined pumps during operation.

2. Full Isolation Anti-Interference Internal Layout

Thickened integrated isolation partitions are arranged between every two pump cavities to completely separate the three oil circuits. Each circuit has independent pressure and flow regulation performance without mutual hydraulic interference or oil cross-flow, ensuring high-precision and stable operation of multi-action synchronous equipment.

3. Three-Stage Graded Pressure Resistance Structure

Different from the unified structural configuration of ordinary pumps, this model adopts zonal reinforcement design according to pressure level. The ultra-high pressure cavity is structurally thickened and optimized for anti-leakage and anti-fatigue, while the medium-pressure cavity adopts streamlined configuration to ensure flow efficiency, balancing structural durability and operating efficiency.

4. Built-In Independent Multi-Channel Control Oil Passage

The pump body is prefabricated with exclusive oil supply, pressure relief and unloading passages for each circuit, realizing integrated internal pressure regulation. No need for external auxiliary valve blocks, with sensitive pressure response and high control accuracy, meeting the precise hydraulic control requirements of intelligent equipment.
