The repair itself usually takes 3-5 business days. - **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. - **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. - **Can I cancel the repair?** Yes, you can cancel the repair after receiving the estimate without incurring any costs. - **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. ### Caterpillar pump service SBS80, SBS120, SBS140 Contact us to quickly restore your machine's efficiency.
