V90N252DPHRH1 F1S8B1NGM Hydraulic Piston Pump Excavator Main Pump Assembly Replacement Digger

V90N252DPHRH1 / F1S8B1NGM Hydraulic Piston Pump – Excavator Main Pump Assembly

The V90N252DPHRH1 / F1S8B1NGM is a variable displacement axial piston pump used as the main hydraulic pump on crawler excavators. The full model string encodes pump size, control arrangement and rotation, which is why the complete code – not only the V90N252 prefix – has to be matched before a replacement is shipped.

Technical Specifications

Key Features

• Full model string matched. Supplied against V90N252DPHRH1 / F1S8B1NGM, including control and rotation configuration, not just the V90N252 prefix.

• OEM-matched interface. Mounting flange, drive shaft spline and port positions follow the original 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

Each character in the model string can change the regulator, control type or rotation direction of the pump, so please confirm your existing pump nameplate reads V90N252DPHRH1 / F1S8B1NGM before ordering. Send us a photo of the nameplate, the regulator side of the pump and the machine model and serial number, and our team will cross-reference within 24 hours.

FAQ by Market

Q1: North America & Europe – how do I confirm the model string before I pay?
Send photos of the old pump nameplate (the full code must be readable), the regulator and the connector, plus your machine model and serial number. We confirm the configuration 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.
