PVV4-1X/082RJ15DMC

The PVV4-1X/082RJ15DMC is manufactured by Bosch Rexroth and belongs to the PV Fixed Displacement Pumps series, where it delivers fixed-volume flow for hydraulic automation loops. With a displacement of 81.6 cm³ per revolution, the unit supplies a precise volume of oil each shaft turn. Its clockwise direction of rotation must be matched when coupling to prime movers to maintain correct inlet and outlet orientation. A minimum permissible speed of 600 min⁻¹ ensures internal lubrication is retained during slow running cycles. The pump can reach 1800 min⁻¹ at a 1 bar inlet, allowing higher flow rates without cavitation. At 1500 rpm it produces up to 120 l/min, giving designers a clear reference for circuit sizing. Continuous system pressure may be held at 175 bar, enabling the pump to serve medium-pressure machinery without overload. The shaft can transmit up to 580 Nm, so drive components must be selected to withstand this torque.

The unit is specified for HLP mineral oil according to DIN 51524-2, ensuring compatibility with common industrial hydraulic fluids. Fluid cleanliness must not exceed ISO 4406 class 20/18/15, which protects internal surfaces against abrasive wear. An allowable fluid temperature up to 70 °C prevents seal degradation and viscosity loss during extended duty. NBR sealing elements are fitted to provide chemical resistance within the stated temperature and oil range. The pressure port sits on the top at 0° from the inlet, permitting straightforward vertical line routing in compact manifolds. That port accepts an SAE 1 1/4 in connection, matching standard high-pressure hoses and valves. The suction side is equipped with an SAE 2 in port to minimize inlet restriction and maintain adequate net positive suction head. A mass of 23 kg must be considered when selecting mounting brackets and during service handling.
