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.
