Typical symptoms of hydraulic pump failure
Slow machine movements
Drop in system speed. Working elements move slowly and response to controls is delayed.
Loss of power
When oil temperature rises the machine loses power. Lifting loads becomes harder and the hydraulic system weakens.
Noise
Whining, squealing, grinding. Noise increases with load and indicates wear or cavitation.
Vibrations
Pump and line vibrations, felt as pulsations or jerks. May indicate worn bearings, uneven oil flow or cavitation.
Characteristics of Liebherr DPVP Pumps
Liebherr DPVP are parallel axial piston variable displacement pumps for open circuits. Designed for high efficiency and reliability, they can supply one or two independent hydraulic circuits from a single prime mover. Nominal pressure is 380 bar, maximum pressure 400 bar.

FAQ - Frequently Asked Questions
-
#1.Hydraulic pump repair - where to start?
To start the hydraulic pump repair process, please contact our repair coordinator, Sebastian. You can call +48 33 870 42 05 or use the contact form on our website.

- Send it by courier.
- After agreeing on the details, we can arrange courier transport.
If you are unable to disassemble the pump, our mobile service can come to you and perform this service. -
#3.What does the repair process look like?
- Dismantling and verification: after delivering the pump to the workshop, we dismantle it into parts and thoroughly verify any damages.
- Estimate and repair time: we prepare a detailed cost estimate and determine the expected completion time.
- Repair implementation: after your acceptance of the terms, we proceed with the repair.
- Testing and painting: after the repair is completed, we test the pump at the testing station.
- A positive test result means that the pump is ready and gets painted. -
#4.What does the offer include?
Our offer may include:
- An estimate for repairs using original parts (if available).
- An estimate for repairs using replacement parts.
- A proposal to purchase the same pump after repair from our warehouse (an alternative to repairing your pump).
- An offer to purchase a new device, if the particular model is in our warehouse. -
#5.How long does the repair of a hydraulic pump take?
Verification begins immediately after the pump is delivered.
You will receive an estimate for typical repairs within just a few hours.
The repair itself usually takes 3-5 business days. -
#6.How do we test hydraulic pumps?
After installation at the test station, the pump is subjected to loads simulating operation in a construction machine. We measure key parameters such as: pressure, flow, torque and oil temperature. We also check changes in efficiency with respect to pressure and the operation of the pump over a wide range of working temperatures. The full test lasts from 4 to 8 hours, depending on the type of pump.
-
#7.What is the warranty after repair?
We perform repairs, using original parts or proven substitutes. After repair, each pump is tested, and the results are documented in the form of a readable chart. Therefore, you receive a 6-month warranty for each repair. If you have any questions about installation or operation, you can use our free phone support.
-
#8.Can I cancel the repair?
Yes, you can cancel the repair after receiving the estimate without incurring any costs.
-
#9.How much does hydraulic pump regeneration cost?
The price depends on the type of pump and the extent of damage. If you provide us with the type of hydraulic pump, we can give you an approximate price range, based on our previous projects.
