Gear oil pump QX Series QX51-100/43-032/22-005R

Product Description

Gear oil pump QX Series QX51-100/43-032/22-005R: Hengmeisi triple gear pump with three independent circuits (rapid idle, heavy-load hold, micro-control). ≤1.5% pulsation. Solves slow response, high energy, low precision under variable loads.

Product Advantages

1. Three-Grade Graded Pressure & Flow Matching, Unique Compound Mode

Breaking the single performance limitation of traditional gear pumps, QX51-100/43-032/22-005R forms a perfect three-level hydraulic gradient. The 100ml/r large-flow circuit realizes fast no-load movement to improve equipment efficiency; the 32ml/r medium-flow circuit undertakes main heavy-load driving; the 5ml/r micro-flow circuit completes ultra-high pressure precise clamping and fine tuning. It can automatically switch working circuits according to equipment load changes, which is incomparable to single pump, equal-displacement double pump and ordinary triple pump.

2. Intelligent Energy-Saving & Low Loss Operation System

Equipped with independent internal unloading and pressure maintaining channels for each stage of the pump. When a single circuit works, the idle circuit automatically unloads and reduces pressure without energy loss, avoiding the long-term high-pressure operation of the whole pump. Compared with traditional multi-pump combined systems, it effectively reduces motor power matching and hydraulic oil heating, greatly lowering equipment operating energy consumption and failure rate.

3. Differentiated Reinforced Configuration for Variable Pressure

According to the pressure bearing demand of each circuit, targeted customized accessories are adopted to balance performance and durability. The medium-pressure large-flow pump core adopts high-efficiency wear-resistant assembly to adapt to long-term continuous flow; the high-pressure pump core uses thickened bimetallic composite side plates and precision grinding gears; the ultra-high pressure micro-flow pump core is equipped with imported ultra-high pressure fluororubber seals and reinforced anti-fatigue bearings. The whole pump can stably withstand 320bar peak pressure, with anti-impact and anti-pollution capabilities far exceeding ordinary standard pumps.

4. Integrated All-in-One Structure, Simplified System Layout

The three-stage pump cores adopt coaxial integrated casting structure, replacing the cumbersome combination of multiple single pumps and multi-group valve blocks in traditional hydraulic systems. One pump body realizes three-circuit independent oil supply, effectively saves equipment installation space, reduces pipeline interfaces and leakage points, and simplifies the overall design and later maintenance of the hydraulic station.

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

QX51-100/43-032/22-005R is a high-end customized compound triple pump in the QX series, specially designed for multi-action, multi-pressure and variable-load complex hydraulic equipment.

Product Structure

1. Coaxial Three-Cavity Graded Integrated Pump Body

Adopts one-piece integral casting molding, with three independent closed pump cavities arranged in series. A single driving shaft synchronously drives three groups of gear assemblies with different specifications, realizing synchronous and independent output of three flows and pressures, with more compact structure than split combined multi-pump.

2. Full Isolation Internal Anti-Interference Structure

Thickened integral isolation partition is arranged between each pump cavity, which completely isolates the oil circuits of the three stages. The pressure and flow of each circuit are independently adjustable without mutual interference or oil cross-flow, ensuring high precision and stability of multi-action synchronous operation of equipment.

3. Graded Anti-Fatigue Wear-Resistant System

Different from the unified configuration of ordinary pumps, this model adopts graded matching according to working pressure. The ultra-high pressure cavity is upgraded with anti-fatigue and anti-leakage accessories, and the medium and medium-high pressure cavities adopt optimized wear-resistant structures, which effectively prolong the overall service life of the pump and avoid partial component failure affecting the whole machine.

4. Built-In Multi-Channel Independent Hydraulic Passage

The pump body is prefabricated with independent oil supply, pressure relief and unloading passages for each circuit. No need for external auxiliary valve blocks, realizing integrated control of fast travel, load driving and precise pressure maintenance, with high integration and convenient installation.
