John Deere KV25952 Hydraulic Pump

The John Deere KV25952 Hydraulic Pump is an assembly of a tandem drive pump for use on compatible John Deere 240 series equipment. According to the published data, this tandem drive hydraulic pump is capable of delivering 16.3 gpm with operating pressure of 215 bar at 2100 rpm. The weight of this assembly is 74 lb with dimensions of 9.1" height, 9.5" width and 21.7" length. These characteristics could be useful for identification, however, the final choice should be based on full machine and part specifications.

The tandem pump is a multi-pumping function assembly which could provide separate demands of hydraulics through a single mechanical driver. KV25952 should match the rotation direction, drive shaft, mounting, ports and gear-pump assembly of the original part. Serial range of equipment should be identified as well because different models could be supplied with different pump assemblies. All hoses and control connection points should be marked before disconnection.

The flow operates at 2100 rpm; however, its real delivery will become smaller due to increased internal wear. Other reasons for heat, slow operation, or drive failure include contamination, clogging of the inlet, issues with the relief valve, or some other problem in the circuit. In case the previous tandem pump did not work, the reservoir and lines must be flushed if needed, filters replaced, and oil tested because a contaminated system may rapidly ruin a new pump.

Drive coupling and adapter must be carefully examined prior to the installation. The pump assembly should be filled or primed with hydraulic fluid and never run dry. It is necessary to start commissioning the pump on light load while paying attention to pressure, flow, noise, leakage, and temperature. Every circuit that is connected to the pump should be examined in order not to confuse partial failure with full failure of the pump.
