HP5V76 Excavator Main Hydraulic Pump Electronically Controlled Piston Pump Assembly Digger

HP5V76 Excavator Main Hydraulic Pump – Electronically Controlled Piston Pump Assembly

The HP5V76 is an electronically controlled variable displacement axial piston pump used as the main hydraulic pump on crawler excavators. Pump output is regulated by an electronic proportional control valve instead of a purely hydraulic regulator, so flow follows the machine controller signal – which is why the pump must be matched to the correct control type, not just to the mounting flange.

Technical Specifications

Key Features

• Electronic control matched to the machine. The proportional control valve and regulator are configured for electronic-control machines, so the pump responds to the controller signal instead of a mechanical linkage.
• Pressure and flow tested. Each pump is bench tested for delivery flow, pressure holding and regulator response before packing.
• OEM-matched interface. Mounting flange, drive shaft spline and port positions follow the original HP5V76 arrangement for direct replacement.
• Complete assembly. Pump body, regulator and control valve are supplied as one unit, reducing installation time on site.
• Factory direct supply. Produced in our Guangdong workshop, with stock available for urgent breakdown orders.

Fitment Notes

Electronically controlled pumps are not interchangeable with mechanically controlled pumps of the same physical size – the control valve, connector type and regulator setting must match your machine. Before ordering, please confirm your excavator model, serial number, the part number stamped on the existing pump, and send a photo of the pump nameplate and of the control valve connector. Our team will cross-reference within 24 hours.

FAQ by Market

Q1: North America & Europe – how do I know it is the right control type before I pay?
Send photos of the old pump nameplate, the control valve and the solenoid connector, plus your machine model and serial number. We confirm the control type and mounting against your unit within 24 hours, and can supply dimension drawings for approval before shipment.

Q2: European Union – what documents come with the shipment?
Each order ships with commercial invoice, packing list and a technical datasheet for customs clearance. Tell us if your market requires additional conformity documents and we will confirm what we can provide for your order.

Q3: Middle East & Africa – how does it cope with heat and contaminated oil?
Hydraulic pump life depends heavily on oil cleanliness. We recommend a new return filter and a flush before installation, and can quote a seal kit together with the pump. Ask us for the oil viscosity and service interval recommendation for your ambient temperature.

Q4: Southeast & South Asia – what is the minimum order and how do we talk price?
Minimum order is 1 unit and the price is negotiable – it depends on quantity, shipping mode and whether you consolidate this pump with other parts in one shipment. Send your target quantity and we will quote accordingly.

Q5: Russia & CIS – can it work in low temperature?
Yes, with the correct hydraulic oil grade. Tell us your winter ambient temperature and we will recommend the oil grade and warm-up procedure, and can quote a low-temperature seal option on request.

Q6: South America & Australia – lead time and after-sales?
Delivery is normally 15–30 days after order confirmation, and warranty terms and claim procedure are agreed with your sales contact before shipment, including how to submit photos or video of the test bench result for assessment.
