Gear oil pump QX Series QX23-005/23-005R09

Product Description

Hengmeisi Gear oil pump QX Series QX23-005/23-005R09 compact dual internal gear pump– direct BUCHER replacement, dual-circuit independent output. Rated 320 bar continuous / 380 bar peak, 5cc/rev per unit, low flow fluctuation, ideal for miniature precision hydraulic equipment.

Product Advantages

1. Dual Internal Meshing vs Single Gear/Vane Pump Structure

Unlike conventional single gear pump or compact vane pump with unstable output, QX23-005/23-005R09 integrates two independent QX23 pump cores inside one pump housing. Dual separate oil inlet & outlet realizes two independent hydraulic loops from one pump body, saving installation space greatly compared with two separated pumps.

2. Mini Fixed Displacement & Ultra-Compact Outline

QX23-005/23-005R09 features 05cc per piece fixed displacement, mini overall dimension specially customized for space-limited installation space. Optimized short tooth profile reduces pump overall length, ideal for embedded hydraulic module layout of small automation devices.

3. Quality Raw Material for Stable Long Service

Gear & shaft: alloy steel carburized quenching and precision grinding for superior wear resistance;Seal: standard R09 specified nitrile seal, applicable -30~+85℃ to avoid high-pressure leakage;Precision needle bearings support continuous rated rotation up to 1500rpm steadily.

4. Oil Contamination Tolerant Internal Structure

Internal meshing structure of QX23-005/23-005R09 delivers better anti-pollution performance than miniature vane pumps, tolerating slightly impure hydraulic oil and reducing unexpected pump stuck failure in compact hydraulic stations.

Model Code

QX23-005/23-005R09 follows original BUCHER coding standard with clear parameter definition for easy buyer identification:QX23:Mini-sized QX23 series small-displacement internal gear pump, apart from large QX83/QX51 series;005:Single pump core fixed displacement of 5cm³/rev;Double 23-005: Twin combined structure, two identical QX23-005 pump cores integrated into one housing;R:Right-hand rotation drive shaft, universal standard rotation for most small host machines;09:Custom seal specification + oil port & mounting flange configuration.

As mini twin pump of QX23 series, QX23-005/23-005R09 targets small dual-circuit precision hydraulic systems, widely purchased by global customers for automation and precision machinery.

Product Structure

1.Core Architecture:Integrated Twin Internal Gear Structure

Different from single gear pump structure, QX23-005/23-005R09 combines two independent inner-outer gear sets within one cast pump casing, two separated flow channels for independent oil supply.

2.Dual Independent Fixed Flow Mechanism

Two 5cc pump cores run separately with fixed displacement, each circuit outputs stable constant flow without variable adjustment, simplifying dual-loop hydraulic control circuit design.

3.Upgraded Component Material

4.Integrated Separate Oil Port Layout

Independent inlet and outlet for each pump core pre-installed at factory, convenient on-site pipeline wiring and later spare part replacement.
