333/G5393 OEM-Quality Hydraulic Gear Pump For JCB

Product Overview: 333/G5393 Hydraulic Gear Pump for JCB 3CX 4CX Enquiries

The 333/G5393 hydraulic gear pump is an engine-mounted, gear-driven single pump referenced for JCB 3CX and 4CX backhoe loader enquiries. Olive Branch Hydraulics manufactures it in Hebei, China, and supplies original-equipment quality (原厂原装品质) against the agreed requirements and builds each order against a confirmed interface drawing or sample. Orders ship EXW Hebei.

Our catalogue confirms the reference 333/G5393 and its single-pump, gear-driven appearance. The published reference configuration is nominal 14 cc/rev, CCW rotation viewed from the shaft end, a T2 1:5 tapered shaft and a K5 flange.

Fitment is not universal. It depends on the exact machine model, PIN/serial number and the interface drawing you approve before production.

The reference also appears as 333G5393 and 333-G5393. Overseas buyers list the same pump as bomba hidráulica 333G5393, pompe hydraulique 333G5393 and гидронасос 333G5393.

Key Features of the 333G5393 Engine-Mounted Pump

Single external gear pump, gear-driven from the engine. The drive gear engages the engine timing train, so the housing interface and drive gear must match your machine exactly.

Nominal 14 cc/rev reference displacement. Displacement is set by gear width and tooth geometry; we confirm it against your drawing or nameplate before cutting gears.

T2 1:5 tapered shaft in the reference configuration. Taper ratio, key size and thread are checked on the drawing, because a 1:5 taper will not seat on a different drive gear bore.

K5 mounting flange in the reference configuration. Bolt pattern and spigot diameter are verified against the approved drawing before machining.

CCW rotation viewed from the shaft end. Rotation is fixed by the internal porting; a reversed-rotation unit is a different build, not a field adjustment.

Gear and bearing construction typical of this pump class. External gear pumps of this type typically use hardened steel gears running in bushings or side plates that seal the gear faces under pressure.

Custom shafts, flanges and ports. Interface features can be machined to your drawing or a returned sample for OEM and project orders.

Pre-shipment inspection on every order. Dimensions on the approved drawing are checked before dispatch, and only verified order-specific documents are issued.

Technical Specifications and How to Select the Right Configuration

Four interface parameters decide whether a 333/G5393 pump will bolt on and run: displacement, rotation, shaft and flange. The table separates our published reference configuration from what must appear on your final order drawing.

Parameter	Published reference configuration	Confirm on the final order drawing
Displacement	14 cc/rev nominal	Displacement stamped on the existing pump or specified by the machine
Rotation	CCW, viewed from shaft end	Rotation of the pump being matched, viewed from the same end
Shaft	T2, 1:5 taper	Taper ratio, key, thread size and shaft length
Mounting flange	K5	Bolt pattern, spigot diameter and seal arrangement
Ports	Not published as a fixed specification	Port type, thread standard, size and orientation
Drive	Engine-mounted, gear-driven single pump	Drive gear compatibility and housing interface

Equipment selection for JCB 3CX and 4CX machines

Record the machine model and PIN/serial number from the data plate.

Photograph the existing pump nameplate, shaft end and flange face.

Compare displacement, rotation, shaft and flange with the reference column above.

Approve our interface drawing before production; it becomes the binding specification for your order.

We do not publish pressure, flow, speed, weight or PIN ranges as fixed values. Those figures depend on the specific build and are stated on the approved drawing.
