The PVV21-1X/060-018RB15DDMB pump belongs to the PV Fixed Displacement Pumps series from Bosch Rexroth and supplies steady hydraulic flow for automation circuits. The unit rotates clockwise to align with common prime mover shafts. It incorporates two fixed displacement stages: the flange side delivers 60.0 cm³ per revolution, while the cover side provides 18.0 cm³ per revolution, allowing simultaneous service to multiple functions. At a shaft speed of 1500 rpm the flange section reaches a maximum flow of 89 l/min, and overall operation is permitted from 600 to 1800 min⁻¹ so flow can be matched to demand. Fluid cleanliness must remain at or below ISO 4406 20/18/15 to protect the internal gear set.
Continuous operating pressure is rated at 210 bar on the cover outlet and 175 bar on the flange outlet, supporting medium-pressure work functions without overstressing the housing. The pump mounts on an SAE-B (101-2) flange and follows SAE J744 dimensional standards, ensuring compatibility with standard engines or electric motors. High-pressure fluid exits through an SAE 3/4-inch port on the cover section and an SAE 1-inch port on the flange section, which simplifies separate circuit plumbing. The suction line connects to a single SAE 2 1/2-inch port that minimizes inlet restriction at higher speeds. All dynamic seals are made from NBR to maintain compatibility with mineral-based hydraulic oils under the specified pressure range.
