Gear oil pump QX Series QX32-012/21-016R

Product Description

Gear oil pump QX Series QX32-012/21-016R – BUCHER-compatible dual internal gear pump, 12cc+16cc, two fine-flow circuits, right-hand rotation. Micro-flow output for fine-tuning & pressure stabilization – overcomes precision limits of single micro-pumps and flow limits of small dual pumps.

Product Advantages

1. Dual Differentiated Micro-Flow Complementary Design

This pump adopts a unique 12cc & 16cc adjacent micro-displacement matching scheme, realizing two sets of fine flow output with subtle difference. The 16cc core provides stable continuous micro-power supply, while the 12cc core undertakes precise flow fine-tuning and pressure compensation. It perfectly adapts to hydraulic equipment that requires both basic operation power and high-precision flow adjustment, making up for the single functional defect of equal-displacement micro dual pumps.

2. Ultra-Low Pulsation & Mute Operation

Optimized fine tooth profile and low-resistance internal flow channel structure greatly reduce flow fluctuation and operating vibration. The dual micro-core synchronous matching operation avoids pressure impact caused by flow difference, keeping the overall system running smoothly. The operating noise is far lower than conventional small gear pumps, meeting the mute operation requirements of precision workshops and laboratory equipment.

3. Lightweight Integrated & Space-Saving Layout

Adopting integral miniaturized casting process, the dual pump body is compact and lightweight with no redundant structural design. Compared with installing two separate micro pumps, the integrated structure greatly saves installation space, simplifies on-site pipeline arrangement, reduces assembly failure points, and improves the overall integration of miniature hydraulic stations.

4. Fine Anti-Pollution & Long Stable Cycle Life

The optimized miniature internal meshing structure has strong tolerance to tiny impurities in low-viscosity hydraulic oil. It can adapt to long-term frequent start-stop and intermittent operation of precision equipment, effectively avoiding micro-jamming and flow deviation of micro pump cores. The high-precision matching parts ensure long-term consistent output accuracy without pressure attenuation.

Model Code

QX32-012/21-016R complies with standard BUCHER coding rules, with clear and refined parameter definitions for micro hydraulic configuration:

QX32-012: QX32 fine-displacement series pump core, 12cm³/rev displacement, for precise flow compensation and fine tuning;

QX21-016: QX21 micro-displacement series pump core, 16cm³/rev displacement, for stable basic micro-flow oil supply;

R: Standard right-hand drive shaft, universal rotation direction, compatible with most precision light industrial and automated hydraulic equipment.

This adjacent micro-displacement dual pump is a specialized model for fine hydraulic control, widely used in high-precision small-load hydraulic systems that require dual-flow collaborative operation.

Product Structure

1. Dual Micro-Core Independent Integration Structure

The integral compact pump body is internally equipped with two independent QX32 and QX21 micro gear assemblies. Isolated sealed flow channels are adopted inside, ensuring completely independent operation of the two micro oil circuits with no flow cross-interference, realizing collaborative dual-function fine oil supply.

2. Collaborative Fine Flow Output Mechanism

Two micro pump cores with subtle displacement differences operate synchronously, forming a complementary flow output system. It can simultaneously meet the basic operating flow and precise fine-tuning flow requirements of equipment, simplify the external valve group configuration, and improve the response accuracy of micro hydraulic systems.

3. Mini Precision Wear-Resistant Configuration

Micro gear sets and drive shafts are finely ground with high-strength alloy steel to ensure low wear and high dimensional accuracy; matched with high-flexibility micro sealing parts to adapt to long-term fine pressure holding; precision miniature bearings ensure stable low-speed and frequent start-stop operation.

4. Compact Standard Interface Specification

Equipped with unified standardized miniature oil ports and mounting flange, consistent with original BUCHER installation standards. It supports direct replacement and quick assembly, no need for equipment modification, convenient for daily debugging, maintenance and spare part replacement of precision hydraulic equipment.
