Olive Branch Hydraulics offers this two-section tandem hydraulic gear pump for JCB 3CX and 4CX backhoe loader main pump enquiries, referenced under catalogue numbers 20/903200 (also written 20903200 or 20-903200) and 20/911200 (20911200, 20-911200).

The pictured unit has a black two-section body, a straight keyed drive shaft (not splined) and a 2-hole oval mounting flange. It also has a four-bolt main port and two opposite capped ports. We build each order against your machine PIN and an approved drawing, with original-equipment quality (原厂原装品质) and confirmed shaft, flange, ports and rotation.

Technical Specifications: What to Confirm Before Ordering

Four interface checks decide whether a tandem pump bolts on and runs on a given machine. The table shows the pictured configuration and what we need from you for each one.

Check	Pictured unit	What to send
Catalogue reference and PIN	20/903200 / 20/911200 (enquiry reference)	Full machine PIN and the part number on the old pump's label
Drive shaft	Straight keyed shaft, not splined	Photo of the shaft end with the key visible, or a drawing
Mounting flange	2-hole oval flange	Flange photo face-on, or drawing with bolt centres
Ports	Four-bolt main port; two opposite capped ports	Port positions, port type and thread or bolt pattern
Rotation	Confirmed per order	Rotation viewed from the shaft end, or the old pump's marking

We do not list displacement, pressure, flow or speed figures on this page. Those values follow the approved drawing for each order.

Valve provision works the same way. Any main relief valve, and its setting, is built only as shown on the approved drawing, as confirmed in the order specification.

Key Features of the Twin Tandem Gear Pump

Two-section tandem layout

Both gear sections share one input shaft in a single stacked body. Section order and the outlet for each section are checked against your drawing before machining.

Straight keyed drive shaft

The pictured unit uses a straight keyed shaft. Splined drives are a different configuration and are not interchangeable with this one, so we confirm the shaft type before quoting.

2-hole oval flange

The two-bolt oval mounting is part of the standard match. Flange variants can be made to your drawing.

Port arrangement

Four-bolt main port, as pictured

Two opposite ports, capped on the pictured unit; open or capped status follows your drawing

Port positions and types can be changed when a drawing or sample shows the requirement

Custom options for OEM and distributor orders

Shafts, flanges and ports machined to an approved drawing or sample

White-label or customer-branded labels

Custom cartons for distributor or private label stock

Pre-shipment inspection

Each order is checked against its approved drawing before dispatch, covering the shaft, flange, ports and rotation. Order-specific inspection documents are issued only where they exist for that order.

FAQ: 20/903200 Tandem Pump Purchasing

Is 20/903200 the same pump as 20/911200?

Not necessarily. We treat both as enquiry references and confirm the actual configuration from your PIN and drawing.

Is the drive shaft splined?

No. The pictured unit has a straight keyed shaft, and a splined version would need its own drawing.

Does the pump include a main relief valve?

Only if your approved drawing shows one. The valve setting also follows the drawing.

Can you change the flange or ports?

Yes. Shafts, flanges and ports can be machined to an approved drawing or sample.

What is the MOQ and lead time?

Both are quoted per configuration and quantity. The same applies to sample cost.

Can the pumps ship under our brand?

Yes. White-label or custom labels and cartons are available on confirmed configurations.

What trade term do you use?

EXW Hebei, China. Payment terms are set out in each quotation.

Which inspection documents come with the order?

Only verified documents specific to that order. Pre-shipment inspection is carried out against the approved drawing.
