333/G5390 OEM-Quality Tandem Hydraulic Gear Pump For JCB

Product Overview

The 333/G5390 hydraulic pump is a two-section tandem gear pump. It is offered for JCB 3CX and 4CX backhoe loader main-pump enquiries, with exact fit confirmed by PIN and interface drawing. Olive Branch Hydraulics supplies original-equipment quality (原厂原装品质) from Hebei, China, on EXW Hebei terms.

The same catalogue row lists 332/G7135 and 7029120077. Buyers also search the part number as 333G5390, 333-G5390, 332G7135 or 332-G7135.

A shared catalogue row is a starting point. It does not prove the pumps interchange.

Before production, we check every order against a confirmed drawing. The check covers the shaft spline, mounting flange, port flanges, rotation and machine PIN.

The part also appears as bomba hidráulica 333/G5390, pompe hydraulique 333/G5390 and гидронасос 333/G5390 JCB 3CX. Distributors, OEM projects and private-label programmes all receive the same configuration check. Custom configurations are recorded on the approved drawing.

Key Features

Two-section tandem layout: two gear sets run on one drive shaft in one assembly. Each section has its own outlet, and the pump mounts at a single point.

Fixed-displacement external gear sets: section displacements are confirmed from the required configuration, nameplate or approved drawing before ordering.

Splined drive shaft: we check the spline profile, tooth count and shaft length against your drawing or sample. If your spline differs, we can machine a custom shaft.

2-hole oval mounting flange: we confirm the pilot diameter and bolt spacing before machining. These dimensions determine whether the pump fits the drive housing.

Four-bolt main port flange: we match the port size, bolt pattern and port position to the approved drawing. Custom port arrangements are available.

Drawing and sample matching: send a drawing, nameplate photo or used core. We measure it and send you a confirmation drawing to approve before production.

Pre-shipment inspection: we check each batch against the approved drawing. Checks cover the shaft, flanges, port positions, rotation arrow and part marking.

White-label marking and packaging: we print your part number, labels and carton artwork from files you supply.

Technical Specifications for the 333/G5390 Hydraulic Pump

Four checks decide whether a twin hydraulic pump bolts on and runs correctly. A full parameter sheet comes after you confirm your configuration.

The displacement and rated pressure of each section can vary between builds that share a catalogue row. We quote these values only after the configuration is confirmed.

If the PIN and the flange details disagree, we resolve the mismatch before quoting.
