PVV1-1X/036RA15RMB

The PVV1-1X/036RA15RMB pump is produced by Bosch Rexroth within the PV Fixed Displacement Pumps series and supplies constant hydraulic flow for mobile and industrial automation networks. It provides a displacement of 36.4 cm³ per revolution, establishing a fixed delivery rate for circuit calculations. With a maximum flow of 53 l/min at 1500 rpm, the unit supports medium-size actuator groups without auxiliary boost pumps. The permitted speed window runs from 600 min⁻¹ to 1800 min⁻¹, allowing engineers to select motor drives that match load cycles. Clockwise rotation is required, so prime movers must couple accordingly to maintain correct inlet and outlet orientation. A SAE-B (101-2) mounting flange lets the housing bolt directly to standard SAE bell housings on combustion engines or electric motors. The pump is designed for HLP mineral oil specified by DIN 51524-2, simplifying fluid selection in existing Bosch Rexroth systems. Its 12 kg mass allows single-person handling during installation while still providing sturdy housing strength.

The continuous pressure capability of 210 bar defines the maximum working line pressure the pump can sustain over extended duty. Drive sizing is assisted by a shaft torque limit of 250 Nm, which indicates the peak twisting load that can be transmitted without damage. A pressure port on the right side at 90° helps route high-pressure lines away from the drive coupling and reduces hose bends. This outlet uses a SAE 3/4 connection, giving compatibility with common 3,000 psi tube assemblies. The suction port is sized at SAE 1 1/2 to minimize inlet velocity and prevent cavitation when the reservoir is remote. NBR sealing material is fitted, providing adequate resistance to the oxidative and thermal properties of standard hydraulic oil. Required fluid cleanliness of ISO 4406 20/18/15 limits particulate load and prolongs bearing and gear life in the internal pumping elements. The combination of port sizing and cleanliness rating supports moderate-pressure circuits that rely on steady flow without cavitation or abrasive wear.
