PVV5-1X/162RB15DMC

The PVV5-1X/162RB15DMC pump belongs to the PV Fixed Displacement Pumps series and is produced by Bosch Rexroth for hydraulic automation circuits. The pump has a fixed displacement of 162.2 cm³ per revolution, so each shaft turn delivers a predictable volume for steady actuator motion. A clockwise rotation direction aligns with common prime movers and simplifies drive coupling orientation. The SAE-C (127-2) mounting flange allows direct installation on standard industrial power units. A pressure port sized SAE 1 1/2 accommodates high-flow pressure lines without excessive velocity. The suction port is SAE 3, giving a large inlet cross-section that reduces cavitation risk at low tank levels. Continuous operation is supported up to 175 bar, enabling medium-pressure tasks such as press drives and forming equipment. Oil cleanliness must reach ISO 4406 code 20/18/15 to preserve internal clearances and extend bearing life. Acceptable fluid viscosity spans from 13 to 860 mm²/s, letting the pump handle thin startup oils as well as thicker fluids found in cold environments.

At 1500 rpm the pump can supply 234 l/min, providing ample flow for multi-circuit manifolds. The maximum permitted shaft speed is 1800 min⁻¹ when inlet absolute pressure is at least 1 bar, which supports faster cycle times in intermittent duty. Inlet pressure may drop to 0.83 bar absolute, so the unit tolerates moderate vacuum on the suction line during rapid acceleration. Conversely, inlet pressure can rise to 2.4 bar absolute, allowing the pump to work with flooded supplies for improved cavitation resistance. Fluid temperature is allowed down to −10 °C, enabling cold-start of outdoor systems, while an upper limit of 70 °C protects seals in high ambient conditions. These operating windows give designers flexibility in reservoir placement and cooling strategy without exceeding component limits.
