Gear oil pump QX Series QX61-160/33-016R08

Product Description

QX61-160/33-016R08 – custom BUCHER replacement dual gear pump with large (160cc) + micro (16cc) displacement combination. Right-hand rotation, 08-series seals. Enables independent high-power main circuit and precise auxiliary control – ideal for applications needing both heavy output and fine regulation.

Product Advantages

1. Unique Large-Micro Displacement Differentiated Matching

This dual pump adopts a rare 160cc large flow matched with 16cc micro flow structural design. The large-displacement core provides powerful main power for equipment rapid action, while the tiny-displacement core undertakes precise pressure holding, fine tuning and micro-action control. It perfectly solves the industry pain point of traditional pumps that cannot balance high power and high precision, avoiding excessive flow waste and control accuracy deviation.

2. Exclusive 08-Spec Sealing & Wide Environment Adaptability

Equipped with standard 08-model customized sealing parts, the pump adopts multi-functional rubber materials with excellent low-temperature resistance and anti-aging performance. It stably operates in a wide temperature range of -25℃ to 85℃, effectively resisting temperature change deformation and micro leakage. The customized sealing structure fits the micro-flow pipeline perfectly, ensuring zero pressure loss in precise control circuits.

3. Fast Response & High-Precision Hydraulic Control

The optimized asymmetric internal meshing tooth profile reduces internal fluid resistance and hydraulic hysteresis. The micro-flow pump core delivers ultra-stable tiny flow output with no pressure fluctuation, while the main pump core maintains efficient high-power output. The overall system response speed is significantly improved, realizing one machine with dual functions of rapid driving and precise positioning.

4. Integrated Compact Structure & Low Operation Loss

Different from discrete double-pump combination, the integrated cast structure minimizes overall installation space. The matched high-precision low-friction bearings reduce idle power consumption and mechanical wear. The dual-core independent non-interference operation design ensures that the precise control circuit will not be affected by the high-power main circuit, maintaining long-term stable control accuracy.

Model Code

QX61-160/33-016R08 follows professional BUCHER coding standards with clear and accurate parameter definitions:

QX61-160: QX61 series large-flow pump core with 160cm³/rev displacement, used for main high-speed and high-power hydraulic driving;

QX33-016: QX33 series micro-precision pump core with 16cm³/rev displacement, specially applied for hydraulic fine-tuning and pressure stabilization control;

R: Standard right-hand rotation shaft, compatible with most mainstream intelligent mechanical equipment;

08: Special configuration code for low-temperature resistant sealing suite and precision micro-flow oil port specification.

This asymmetric dual-displacement composite pump is tailor-made for precision heavy-duty hydraulic systems, filling the demand gap of simultaneous high-power driving and micro-precision control.

Product Structure

1. Asymmetric Dual-Core Integrated Layout

The pump body adopts one-piece high-rigidity casting, built with two pump cores of completely different displacement specifications. The internal independent isolation flow channel structure ensures that the large-flow oil supply and micro-flow control work independently without mutual flow interference, realizing dual functional integration.

2. Dual-Function Fixed Flow Output System

The large-displacement core outputs constant high flow for rapid equipment operation, and the micro-displacement core provides stable precise flow for positioning and pressure maintaining. The dual fixed-flow matching mode simplifies complex hydraulic control valves and reduces system failure points.

3. Precision Customized Component Configuration

The gear group adopts asymmetric precision grinding process to adapt to different flow output requirements; the 08 low-temperature resistant sealing assembly is specially optimized for micro-flow circuits to prevent micro-leakage; high-sensitivity bearings ensure flexible start and fast response under low-temperature and light-load conditions.

4. Micro-Flow Optimized Oil Port Design

The auxiliary circuit adopts finely optimized micro oil port structure, which improves flow control accuracy. All interfaces are standardized and pre-installed, supporting quick assembly and precise pipeline matching, convenient for later maintenance and debugging of precision hydraulic systems.
