The PVV5-1X/183LA15UMC pump belongs to the PV Fixed Displacement Pumps series from Bosch Rexroth and supplies constant-volume flow to hydraulic automation circuits. It turns anti-clockwise, a direction chosen for installations that align with left-hand prime movers. A displacement of 183.4 cm³ per revolution sets the theoretical delivery rate, while the cylindrical drive shaft in version A simplifies coupling with gearboxes. The shaft diameter measures 31.75 mm to transmit the required torque. Under a 1 bar inlet the unit can operate up to 1800 rpm, and it remains stable down to a minimum speed of 600 rpm during idle cycles. At 1500 rpm it provides a flow of 267 l/min, giving reliable supply for medium-size actuators. Attachment to engines or electric motors is handled by an SAE-C flange with a 127 mm pilot, allowing drop-in replacement on standard mounts.
It accommodates fluid temperatures between −10 °C and +70 °C so cold starts and normal service fall within limits. A viscosity window of 13 to 860 mm²/s keeps lubrication and volumetric efficiency within specification across different oil grades. Inlet pressure may range from 0.83 to 2.4 bar, which prevents cavitation at varying tank heights. The pump is designed for HLP mineral oil conforming to DIN 51524-2 to ensure compatibility with seals and internal coatings. Continuous outlet pressure is permitted up to 175 bar, and a maximum drive shaft torque of 610 Nm resists mechanical overload at that rating. High-pressure flow exits through an SAE 1.5-inch port, while suction enters through an SAE 3-inch connection to minimize line losses. These interface dimensions integrate the unit into fixed-displacement power packs without additional adapters.
