Working elements move slowly, delayed reaction to control. ### Loss of power When hydraulic oil temperature rises. After warming up, the machine loses power, lifting loads becomes more difficult. ### Noise Abnormal sounds: whining, squealing, grinding. Noise often increases with load, indicating wear or cavitation. ### Vibrations Pump and hose vibrations. Felt in the cab as pulsations or “jerking”. Indicate worn bearings, uneven oil flow or cavitation. ## Characteristics of Liebherr LPVD pumps LPVD are double axial piston variable displacement pumps for open circuits. Nominal pressure 350 bar, maximum 380 bar. Modular design (EL/SD/DA regulators, Power/Load Sensing, stroke and power limiters), SAE/DIN/ISO flanges, possibility of through-drive and auxiliary gear pumps. Besides the LPVD, we repair many other pump series – see the full scope of our [hydraulic pump service](https://wibako.com/services/repairs-of-hydraulic-pumps-and-motors). ### LPVD 45 - Displacement: 45.6 cm³/rev - Max. speed: 3000 rpm - Flow at nmax: 137 l/min - Power (350 bar): 91 kW - Torque (350 bar): 290 Nm ### LPVD 64 - Displacement: 64.3 cm³/rev - Max. speed: 2760 rpm - Flow at nmax: 177 l/min - Power (350 bar): 118 kW - Torque (350 bar): 408 Nm ### LPVD 75 - Displacement: 75.0 cm³/rev - Max. speed: 2540 rpm - Flow at nmax: 191 l/min - Power (350 bar): 127 kW - Torque (350 bar): 477 Nm ### LPVD 90 - Displacement: 90.7 cm³/rev - Max. speed: 2430 rpm - Flow at nmax: 220 l/min - Power (350 bar): 147 kW - Torque (350 bar): 578 Nm ### LPVD 100 - Displacement: 103.1 cm³/rev - Max. speed: 2320 rpm - Flow at nmax: 239 l/min - Power (350 bar): 159 kW - Torque (350 bar): 654 Nm ### LPVD 107 - Displacement: 107.6 cm³/rev - Max. speed: 2290 rpm - Flow at nmax: 246 l/min - Power (350 bar): 164 kW - Torque (350 bar): 684 Nm ### LPVD 125 - Displacement: 125.6 cm³/rev - Max. speed: 2180 rpm - Flow at nmax: 274 l/min - Power (350 bar): 183 kW - Torque (350 bar): 802 Nm ### LPVD 140 - Displacement: 141.2 cm³/rev - Max. speed: 2150 rpm - Flow at nmax: 304 l/min - Power (350 bar): 203 kW - Torque (350 bar): 902 Nm ### LPVD 150 - Displacement: 151.4 cm³/rev - Max. speed: 2100 rpm - Flow at nmax: 318 l/min - Power (350 bar): 212 kW - Torque (350 bar): 964 Nm ## What we do as part of the service ### Diagnostics & tests Pressure measurement, flow tests, test bench verification. ### Overhaul Replacement of rotating elements, seals, surface finishing. ### Calibration Precise adjustment of valves and controls. ### Upgrades Selection of replacements and adaptations. ### Door-to-door Pick-up and delivery throughout Poland. ### Warranty & report Test protocol and warranty up to 12 months. ## Supported machine brands Ahlmann Akerman Atlas Bobcat Bomag Case Caterpillar Claas Clark Daewoo Doosan Dressta Dynapac Eder Fuchs Furukawa Hanomag Hitachi Hyundai Jcb John Deere Kaelble Kawasaki Kobelco Komatsu Kramer Kubota Liebherr Linde Manitou Mecalac Moxy New holland O&K Samsung Sennebogen Terex Volvo Wirtgen Zeppelin Zettelmeyer Manufacturer names for information purposes only – independent service. ## What the repair process looks like 1 ### Contact By phone or via the form. 2 ### Collection We arrange a courier; on-site disassembly possible. 3 ### Diagnostics Disassembly, measurements, cost estimate for approval. 4 ### Repair & test Assembly, calibration, test bench verification. ## Customer reviews **“LPVD works like new after overhaul.”** Quick diagnosis, full power restored. - Chris **“Professional contact and punctuality.”** WIBAKO did an excellent job. - Andrew **“I recommend WIBAKO service.”** Test bench verification and written warranty. - Michael ## FAQ - frequently asked questions - **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](tel:+48338704205) or use the [contact form](https://wibako.com/contact) on our website. - **How to deliver a pump for repair?** You have several options: - Deliver it personally to our workshop. - 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. - **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. - **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. - **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. - **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. ### Problem with a Liebherr LPVD pump?
