PVQ5-1X/193R

The PVQ5-1X/193R pump is manufactured by Bosch Rexroth within the PV Fixed Displacement Pumps series. It is a fixed displacement vane pump intended to supply constant flow in hydraulic automation loops. The build size of 5 defines the housing dimensions and matches medium-frame power units. Each revolution displaces 193.4 cm³ of fluid, allowing predictable volume delivery for proportional valve groups. Shaft coding “R” specifies clockwise rotation so the drive can be aligned with standard right-hand engines. Because the inlet and outlet are independent of rotation, the manifold can be mounted without re-plumbing if the motor direction changes. The unit is designed for HLP mineral oil conforming to DIN 51524-2, which simplifies compatibility with common industrial fluids.

ISO 4406 cleanliness code 20/18/15 sets the maximum particle level permitted in the oil to protect the vane set from abrasive wear. The continuous pressure rating of 175 bar defines the highest system pressure that can be applied without reducing service life. At 1500 rpm the pump delivers a flow of 285 L/min, providing sufficient supply for multiple cylinders or large displacement motors. A minimum speed of 600 rpm is required to maintain stable lubrication, while the maximum speed of 1200 rpm applies when fire-resistant HFD-R fluid is used to limit thermal loading. These speed limits let designers match the prime mover to duty cycles without cavitation or excessive heat. Together, these parameters give a clear operating window for reliable high-volume hydraulic circuits.
