Sheungchak hydraulic piston pumps include fixed and variable displacement models for open-circuit hydraulics and closed-circuit hydrostatic drives. Browse A4VSO, A10VSO, A11VO, A4VG, A2FO, A17FO and mobile pump assemblies, then open the relevant product page for its specifications.
For OEM equipment or a replacement order, select by circuit, displacement and control first. The shaft, flange, rotation and port configuration are checked against the complete model code.

Find the right pump for your hydraulic circuit
Choosing a piston pump starts with the circuit and the output needed by the machine.
Sheungchak offers different axial piston pump designs for pressure-controlled hydraulic systems, hydrostatic drives and fixed-flow installations.
Open-circuit variable pumps
A4VSO, A10VSO, A11VO and K3V series can adjust displacement for the required hydraulic output. Compare the control configuration as well as pump size.
Closed-circuit variable pumps
A4VG pumps are used in hydrostatic drive loops. Charge and control arrangements form part of the series configuration.
Fixed-displacement pumps
A2FO and A17FO use bent-axis designs that deliver a fixed theoretical volume per shaft revolution.
Compare hydraulic piston pump models and applications
The series below cover different machine requirements. Use the model page to check its displacement range,
pressure class, control options and connection details before specifying a unit.
| Pump series | Circuit | Displacement type | Common selection context |
|---|---|---|---|
| A4VSO | Open circuit | Variable, swashplate | Industrial hydraulic systems with flow and pressure control |
| A10VSO | Open circuit | Variable, swashplate | Open-circuit hydraulic power and control systems |
| A11VO / A11VLO | Open circuit | Variable, swashplate | Mobile machinery with changing hydraulic flow demand |
| A4VG | Closed circuit | Variable, swashplate | Hydrostatic travel and traction drives |
| A2FO | Open circuit | Fixed, bent-axis | Fixed-displacement pump supply for suitable open circuits |
| A17FO | Open circuit | Fixed, bent-axis | Truck PTO and auxiliary hydraulic functions |
| K3V112 / K3V112DT | Open circuit | Variable; tandem options | Mobile equipment main and tandem pump assemblies |
| AP2D36 | Open circuit | Variable double pump | Mobile hydraulic systems with two pump sections |
Check these details before specifying an axial piston pump
A matching pump size is only part of the selection. Use the three checks below to narrow the specification for a new hydraulic system or an existing machine.
01
Circuit and displacement
Confirm open circuit or closed circuit, then the required flow or displacement at the operating speed.
02
Pressure and regulation
Record working pressure, peak duty and the type of pump control, such as pressure compensation or load sensing where applicable.
03
Fit and connections
Check drive rotation, shaft end, mounting flange, hydraulic ports, drain lines and any through-drive interface.
An open-circuit or closed-circuit piston pump operates within a different hydraulic arrangement. Establishing that distinction early avoids choosing the wrong pump family.
Match a replacement pump to the installed unit
Sheungchak replacement piston pump enquiries begin with the full ordering code. For example, A4VG90 and A4VG125 are members of the same series, but their sizes and associated configurations are different.
Send a clear hydraulic pump nameplate photo or the complete type code, along with shaft and flange photos if the old pump is still installed. The pump replacement specifications also include port layout, rotation and control settings.
For an aftermarket axial piston pump enquiry, include the equipment model, required quantity and delivery country so Sheungchak can review the request against the selected series.
OEM piston pump configurations for equipment manufacturers
Sheungchak OEM hydraulic piston pump supply starts from an established pump series or an approved equipment specification. Buyers can identify the required displacement, control method and installation interfaces for quotation.
For machinery manufacturers, the project details may include shaft and flange options, rotation, hydraulic ports, seals and nameplate requirements. Final choices depend on the chosen pump platform and confirmed drawings.
For distributors placing repeat or bulk pump orders, share the approved full model code, quantity, destination and any marking or packaging requirements. That provides a consistent specification for subsequent orders.
Frequently asked questions about pump selection
What is the difference between a fixed and a variable displacement axial piston pump?
A fixed-displacement model delivers a fixed theoretical oil volume per shaft revolution. A variable-displacement model adjusts output through its control mechanism. A2FO and A17FO are fixed-displacement examples, while A4VSO, A10VSO, A11VO and A4VG are variable models in this category.
Which models are designed for closed-circuit hydrostatic drives?
A4VG belongs to the closed-circuit variable pump range. A4VSO, A10VSO and A11VO are open-circuit series. Confirm the circuit and auxiliary connections before comparing their sizes.
What should I send when requesting an OEM or replacement pump quotation?
Send the pump family or complete model code, circuit type, operating pressure, flow or displacement, control arrangement and installation interfaces. For a replacement, add a nameplate photo. Include quantity and destination for purchasing review.
