This catalog covers hydraulic gear, vane and piston pumps, orbital and piston motors, valves, steering units and spare parts for construction machinery, tractors and industrial power units. Most items are replacements for Rexroth, Parker, Vickers, Yuken, Danfoss and Eaton series. We match each part to its complete original product code and machine model, so you don't have to rely on a photo or a series name.
What You Get From This Range
Code-based matching
Send us the original product code, the machine model and the equipment details. We check the full assembly code because shaft, flange, rotation and ports can differ within the same series.
Wide series coverage
Piston pumps include the A10VO, A4VG, PVH and K3V series. Vane pumps cover T6/T7, PV2R and SQP, gear pumps cover AZPF, PGP and ALP/GHP, and orbital motors run from OMP to OMV.
Custom gear pumps
We make OEM and aftermarket gear pumps to your specification, including custom P/T port layouts. You approve drafts and 3D renders before sampling starts.
100% final inspection
Every unit is checked before it is packed. The test scope is agreed in the quotation and can include dimensional checks, leak testing and pressure/flow testing.
Our Product Range
Which Hydraulic Pump or Motor Fits Your Application?
The duty cycle of the machine decides the pump or motor type. Start from the machine, then narrow down by code.
Backhoe loaders and compact construction machines
Tandem and multi-section gear pumps feed the loader, backhoe and steering circuits at once. They need to tolerate frequent pressure peaks and contaminated field conditions. Our JCB-type tandem gear pumps, such as 332/F9032, 20/925341 and 333/G5390, are matched by part number.
Excavators and heavy earthmoving
Main pumps on excavators usually run as variable-displacement piston units, which adjust flow to the load and limit heat. Typical replacements here are the K3V, A8VO and A11VO series. Regulator type and control options must match the original code.
Agricultural tractors
Tractor hydraulics run the hitch, loader and power steering, often from a gear pump driven directly by the engine or transmission. For these circuits we supply tractor hydraulic pumps, transmission pumps and hydraulic steering units.
Hydrostatic drives (rollers, pavers, harvesters)
Closed-circuit travel drives pair a variable pump such as the A4VG or A10VG with a piston motor such as the A6VM or A2FM. Pump and motor displacement and control settings must work together, so we quote the pair against the machine model.
Slow, high-torque drives (augers, sweepers, winches, conveyors)
Orbital motors deliver high torque at low speed without a gearbox. Disc-valve designs such as the BMER (100–750 cc/rev), BMSY (80–630 cc/rev) and BMV (250–1600 cc/rev) usually handle higher pressure and longer duty than spool-valve types. Pick the displacement from the speed and torque you need.
Industrial power units, presses and machine tools
Vane pumps such as the T6/T7, PV2R and SQP run quietly with low flow pulsation, which suits indoor stationary equipment. Where the system needs pressure compensation or high continuous pressure, variable piston pumps such as the A4VSO, PV and PVH are the usual choice.
Replacing Tandem Gear Pumps on Backhoe Loaders: What to Check
Tandem pumps cause the most wrong-part returns in this category. These checks avoid most of them.
Why similar part numbers are not interchangeable
A tandem gear pump has two pumping sections on one drive shaft. Each section supplies a different circuit, so the displacement of each section is set for that circuit. Codes such as 332/F9029, 332/F9030, 332/F9031 and 332/F9032 can look almost identical on the bench. They can still differ in section displacement, shaft spline, port positions or the relief arrangement. If you fit a pump with the wrong front or rear section, cycle times or steering response usually change, even when the pump bolts on.
What we need to identify the pump
The most reliable reference is the part number on the pump body or label, together with the machine model and serial range. If the label is gone, send photos of the shaft end, mounting flange and port faces, plus the shaft spline count and the port thread sizes. We check these details against the full assembly code before we quote. If the evidence does not support a confident match, we tell you.
Inspection before dispatch
Every unit is inspected before packing. Gear pumps can be leak-checked and pressure/flow tested where applicable, and you agree the test scope in the quotation. If a shipment goes into distributor stock, you can also specify labeling by OEM reference so warehouse staff can pick the right part without opening the box.
For tandem pumps, the complete part number decides fitment. Physical resemblance does not.
Custom Gear Pumps, Private Label and Wholesale Supply
Distributors and machinery parts suppliers can order catalog replacements or gear pumps built to their own specification.
Displacement and section combination
Single, tandem, triple and quadruple gear pumps can be built to your flow requirements for each circuit.
P/T port configuration
Port positions and thread types can be set to match your installed base or your stock program.
Shaft and mounting
Shaft and flange options can be specified to fit the target machine or power unit.
Branding and labeling
Private-label marking and carton labeling can be agreed per order.

Hydraulic Pump and Motor Sourcing FAQ
- Are your pumps original Rexroth, Parker or Danfoss products?
- No. They are replacement units. Brand names and model numbers are given only so you can identify the right part, and compatibility depends on the complete assembly code.
- What information do you need to quote a replacement part?
- Send the original product code, the machine model and the equipment details, plus the quantity and your destination port. If the code is not readable, photos of the shaft, flange and ports help us narrow it down.
- How fast will I get a quotation?
- We reply within 24 hours once we have the model, quantity and destination port. If we need to confirm a match, we will ask for the missing details instead of guessing.
- What inspection is done before shipment?
- Every unit gets a 100% final inspection before packing. Depending on the product, the agreed scope can cover dimensional checks, leak inspection and pressure/flow testing.
- Do you provide certificates?
- The documents for each order are agreed in the quotation. Third-party certificates or document references remain the property of their holders. They are not certifications of Olive Branch Hydraulics.
