The PVV4-1X/098R fixed displacement pump is part of the PV Fixed Displacement Pumps series from Bosch Rexroth and is intended to deliver constant flow in hydraulic automation circuits. It moves 97.7 cm³ of fluid each revolution, while a continuous outlet rating of 175 bar supports medium-pressure systems. At 1,500 rpm the pump supplies up to 141 l/min, provided the hydraulic fluid cleanliness is maintained at ISO 4406 20/18/15. Safe operation is possible between 600 and 1,800 rpm, giving designers a useful speed window. The shaft is configured for clockwise rotation, and installation is by an SAE J744 flange for straightforward coupling to standard power units.
The unit is designed for HLP mineral oil defined by DIN 51524-2 and tolerates inlet pressures from 0.83 bar absolute to a maximum of 2.4 bar absolute, preventing cavitation and seal overload. Fluid temperature may range from -10 °C to +70 °C, while acceptable viscosity spans 13 mm²/s to 860 mm²/s, allowing operation with both light and heavy oils. The pump weighs 23 kg, a consideration for mounting hardware and service handling.
