332/F9031 OEM-Quality Tandem Hydraulic Gear Pump For JCB

332/F9031 Tandem Gear Pump: Product Overview

Olive Branch Hydraulics offers the 332/F9031 tandem hydraulic gear pump with original-equipment quality (原厂原装品质) for JCB 3CX and 4CX backhoe loader main hydraulic pump enquiries. Each pump is built and inspected to the drawing you confirm, and we quote EXW Hebei, China.

This page covers four catalogue references: 332/F9031, 20/925581, 333/G5391 and 7029120078. Use them to start an enquiry. On their own, they do not confirm fit.

Two machines with the same model name can carry different pump builds. Before quoting, we confirm the full machine PIN, drive shaft, flange, ports and rotation.

You can order as wholesale stock, as an OEM/ODM build to your drawing or sample, or as private label with your own nameplates and cartons.

Technical Specifications: What to Confirm Before You Order

Fit depends on four things: the shaft, the flange, the ports and the rotation. If any one is wrong, the pump will not install, even when the part number matches.

Parameter	What We Check	What You Send
Machine PIN	Which pump build applies to the catalogue reference	Full PIN from the machine plate
Drive shaft	Spline profile, tooth count, length and pilot	Drawing, measured photo or the old pump
Mounting flange	Two-hole oval pattern, bolt centres and spigot	Drawing or measured sketch
Ports	Four-bolt main port, capped opposite ports, thread or flange standard	Port photos and thread readings
Rotation	Direction viewed from the shaft end	Old pump nameplate or circuit drawing
Section sizes	Front and rear section displacement	Drawing or nameplate data

Catalogue References and Written Variants

332/F9031: also written 332F9031 or 332-F9031

20/925581: also written 20925581 or 20-925581

We also accept RFQs that name the part in other languages, such as bomba hidráulica 332/F9031, pompe hydraulique 332F9031 or гидронасос 332/F9031. JCB names and part numbers are used here for identification only.

We do not treat any of these references as interchangeable without checking. If your old pump differs from the drawing, we build to the measured sample, but only after you approve the difference in writing.

Key Features of the JCB 3CX / 4CX Tandem Hydraulic Pump

A single splined input shaft drives both pumping sections. The rest of the pump is built to the build you confirm.

Two-section tandem layout: front and rear gear sections are stacked in line. The circuit arrangement must match your approved drawing.

Splined drive shaft: machined to the confirmed spline profile and length. We check it against your drawing or sample before assembly.

Two-hole oval flange: the mounting face and spigot are machined to the confirmed pattern. You can order a different flange if your gearbox mount needs one.

Port arrangement: a four-bolt main port on one side and two capped ports on the opposite side. The port standard follows your drawing.

Finish and transit protection: black paint, with every open port capped before packing. This keeps dirt out of the gear chambers.

Identification: nameplates or labels can show your part number, our catalogue reference or your brand.

Repeat orders should identify the approved drawing revision and any changes required.

Why Choose Us: Production, Inspection and Supply Options

FAQ: Sourcing the 332/F9031 Pump
