Gear oil pump QXV Series QXV41-040R

Product Description

Searching for an energy-saving variable pump with automatic flow adjustment? Hengmeisi Gear oil pump QXV Series QXV41-040R – V-type variable internal gear pump, 40cc, stepless flow adjustment, 300 bar, 95% efficiency, load-adaptive, low energy – ideal for intelligent energy-saving hydraulic systems.

Product Advantages

1. Stepless Variable Flow Regulation & Energy Saving

Equipped with an integrated precision variable control mechanism, QXV41-040R realizes real-time stepless adjustment of output flow. It automatically matches the required flow according to equipment operating procedures, avoiding continuous full-flow output of fixed-displacement pumps. It significantly reduces idle power consumption and hydraulic heat generation, achieving outstanding energy-saving effects and lowering long-term equipment operating costs.

2. Intelligent Load Adaptive Performance

The optimized variable sensing structure can sensitively perceive changes in hydraulic system load and pressure. It automatically adjusts flow and pressure output in real time, maintaining stable system pressure during equipment static pressure holding and low-speed operation, and providing sufficient flow supply during high-speed action. The adaptive working mode greatly improves the intelligent level of hydraulic equipment.

3. Low Heat Generation & Stable Long-Term Operation

Thanks to the active flow matching design, the pump avoids ineffective hydraulic overflow and pressure loss, greatly reducing system heat generation compared with traditional overflow pressure regulation pumps. The internal meshing structure with low friction loss cooperates with high-precision matching parts, ensuring low-noise, low-vibration and stable continuous operation, and extending the service life of hydraulic components.

4. Integrated Variable Structure & Easy Installation

Different from external variable valve assembly structures, this pump integrates the variable adjustment core inside the integral pump housing. The overall structure is compact and integrated without additional auxiliary control accessories. It reserves standard installation dimensions consistent with the original BUCHER pump, supporting direct replacement and quick on-site installation and debugging.

Model Code

QXV41-040R complies with standard BUCHER series coding specifications, with clear and intuitive parameter definitions:

QXV41: Upgraded V-type variable QX41 series, specially designed for adjustable flow hydraulic systems, different from fixed QX41 series pumps;

040: Standard benchmark displacement of 40cm³/rev, supporting adjustable flow range based on working load;

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

As a classic single variable pump of the QXV series, QXV41-040R focuses on medium-flow energy-saving variable control, widely recognized for intelligent and energy-saving transformation of various standard hydraulic stations.

Product Structure

1. Built-In Variable Adjustment Core Structure

The pump adopts an innovative integrated structure, integrating precision variable sensing components, adjustment valve core and internal meshing gear set inside the integral cast pump body. The built-in variable mechanism features sensitive response and compact layout, realizing integrated flow adjustment and power output.

2. Adaptive Flow Pressure Control System

Equipped with independent pressure sensing and flow feedback components, the pump can monitor system pressure changes in real time and automatically adjust the pump core displacement. It forms a closed-loop adaptive control system, ensuring dynamic balance between equipment load and hydraulic output.

3. High-Precision Wear-Resistant Configuration

The main gear set is made of carburized alloy steel after precision grinding for stable wear resistance; the variable adjustment valve core adopts fine finishing process to ensure accurate and flexible adjustment without jamming; high-quality sealing parts prevent internal leakage and ensure adjustment accuracy.

4. Standard Universal Mounting Structure

The overall installation flange, oil port size and shaft diameter strictly follow industry standard specifications. It is highly versatile and interchangeable with original imported pumps, supporting direct replacement and no need to modify equipment pipelines and mounting bases.
