Gear oil pump QX Series QX63-100/41-040R12

Product Description

Hengmeisi Gear oil pump QX Series QX63-100/41-040R12 – China factory direct replacement for Bucher. Combines 100cc & 40cc cores. 320/385 bar, R12 custom, two isolated flow paths, reduced fluctuation. Ideal for split-load main & auxiliary hydraulics.

Product Advantages

Graded Medium Dual-displacement vs Uniform-volume Twin Gear Pump Designs

Unlike twin pumps with identical displacement or extreme big-small flow difference, QX63-100/41-040R12 adopts adjacent medium flow matching of 100cc and 40cc. The 100cc core bears main equipment load drive while the 40cc core undertakes auxiliary pressure shunting and circuit compensation, eliminating redundant flow waste caused by full-flow simultaneous output of equal-spec dual pumps and optimizing overall hydraulic energy consumption.

Exclusive R12 Custom Sealing & Mounting Specification

Equipped with non-universal R12 dedicated sealing assembly and matched mounting flange, this QX63-100/41-040R12’s customized rubber seal adapts -22℃~+88℃ working environment, specially optimized for medium-pressure intermittent load conditions. The exclusive flange dimension differs from R08/R308 standard versions, strengthening overall sealing tightness to prevent intermittent high-pressure leakage during frequent load switching.

Low-vibration Optimized Tooth Profile for Silent Operation

Upgraded arc-modified internal gear tooth profile reduces meshing clearance fluctuation and mechanical vibration of QX63-100/41-040R12. Its running noise is far lower than conventional combined gear pumps, satisfying mute production requirements of enclosed precision processing workshops and indoor automated production lines.

Gradient Flow Channel Built-in Anti-dirt Adaptability

QX63-100/41-040R12’s internally stepped flow passage forms natural impurity interception structure without extra external filter. The gradient channel can block medium-sized particle contaminants inside hydraulic oil, lowering gear jamming failure rate and cutting peripheral accessory installation cost for end users.

Model Code

The model code QX63-100/41-040R12 follows standard BUCHER coding specification with clear parameter definition for easy purchaser identification:

QX63: Independent medium-large QX63 pump series, separate from QX51/QX83 large-displacement platform;

100: Fixed displacement of 100cm³/rev for main circuit load driving;

QX41: Medium-small QX41 series pump core for auxiliary shunting loop;

040: 40cm³/rev fixed displacement specially for pressure compensation and flow split;

R: Right-hand standard drive shaft rotation;

12: Exclusive customized configuration code covering dedicated HNBR sealing set and special-size mounting flange.

As a unique adjacent-medium combined pump in QX series, QX63-100/41-040R12 is customized for split-load dual-circuit hydraulic systems and widely sourced by global buyers for plastic machinery and multi-station machine tool supporting.

Product Structure

1.Core Architecture: Partitioned Dual Medium Internal Meshing Structure

Different from non-isolated integrated twin pump body, QX63-100/41-040R12 adds integral casting partition inside pump casing, splitting inner cavity into two independent chambers for respective QX63 and QX41 gear assemblies.

2.Split-load Fixed-flow Shunting Mechanism

Two pump cores keep respective fixed displacement output: the 100cc core provides full flow for primary equipment movement, while the 40cc core diverts partial oil for auxiliary pressure stabilization, simplifying external flow dividing valve configuration of hydraulic system.

3.R12 Spec Upgraded Matching Components

Gear groups adopt carburized precision grinding alloy steel for medium-load wear resistance; R12 exclusive customized sealing parts match pump housing oil port size; high-precision intermediate bearings withstand alternating load of dual-circuit asynchronous operation.

4.R12 Standard Pre-assembled Oil Port Layout

All inlet and outlet ports are pre-machined per R12 exclusive dimensional standard at factory, consistent with original BUCHER R12 spare part size, supporting direct replacement without on-site pipeline modification.
