At DV Hydraulics, we recently carried out a complete overhaul and extensive testing of a Hägglunds SP500 hydraulic pump on our test bench. From initial start‑up to heavy load testing, this unit is once again ready for many years of reliable operation.

Hägglunds pumps are typically used in heavy industrial applications where high torque, robustness and operational reliability are critical.

Complete Overhaul According to OEM Specifications

The performed overhaul included:

• Complete disassembly and inspection of all internal components

• Replacement of the complete drive mechanism

• Restoration and correct zero‑point adjustment of the pump

• Inspection and adjustment of all valves

• Reassembly according to OEM guidelines

Each step was carried out with a strong focus on accuracy and durability, ensuring the motor once again meets its original performance specifications.

Extensive Testing Under Realistic Load Conditions

After the overhaul, the Hägglunds SP500 was tested on our test bench, specifically designed for heavy hydraulic components:

• Tested under loads exceeding 300 bar

• Torque during testing up to 3000 Nm

• Stability and performance verified under realistic operating conditions

Thanks to this test capacity, we can easily test large pumps and motors well above 500 cc, both functionally and under full load.

This provides maximum assurance after overhaul.

Reliability Before Commissioning

Our test bench was built with one clear objective: to guarantee reliability before the pump or motor is returned to service.

Only after successful testing is the unit released — in this case, following the application of a new protective paint coating.
