The PVV4-1X/098RA15DVC pump is manufactured by Bosch Rexroth for the PV Fixed Displacement Pumps series and supplies a constant volume flow for hydraulic automation systems. It displaces 97.7 cm³ per revolution to support circuits that need steady delivery. When driven at 1500 rpm, the pump provides a flow rate of 141 L/min for medium-capacity machinery. A continuous operating pressure of 175 bar allows the unit to maintain reliable force in closed-loop applications. Clockwise shaft rotation is specified, so motor orientation must match this direction. The pump is intended for HLP mineral oil conforming to DIN 51524-2, ensuring lubrication and sealing properties are maintained. Suction conditions must remain above 0.9 bar absolute, and the returning fluid must meet ISO 4406 20/18/15 cleanliness to avoid internal wear.
A 127-2 (SAE-C) mounting flange integrates the housing with standard power-takeoff pads on industrial drives. SAE suction and pressure ports with UNC threads simplify hose selection across global installations. The suction side uses a dedicated SAE 2 in connection to minimize inlet velocity and resist cavitation, while the pressure side terminates at an SAE 1 1/4 in fitting for high-flow discharge. The pressure port is located on the top face at 0° from the inlet, which eases manifold alignment in horizontal layouts. FKM seals are fitted to withstand the specified mineral oil and elevated temperatures. Overall weight is 23 kg, allowing single-person handling with proper lifting tools.
