The PFB10FRY31 pump belongs to the Piston Pumps series and is manufactured by Vickers for hydraulic automation circuits. Its geometric displacement is 21.1 cm³ per revolution, determining how much fluid moves with each shaft turn. At 1800 rpm the unit delivers 37.8 l/min (10 US gpm), and it can accelerate to a maximum speed of 3200 rpm where the theoretical flow rises to 68.1 l/min (18 US gpm). A working limit of 210 bar defines the highest system pressure the pump can sustain, while the shaft can absorb up to 26.1 kW (35 hp) from the prime mover. Rotation is right-hand (clockwise), and a foot bracket mounting style positions the housing securely on a base or skid.
The mounting interface uses a 120.6 mm (4.75 in) bolt circle to align the pump with the driven equipment. Two main ports carry 1.625-12 UN-2B threads for pressure and return connections, and a separate case drain outlet is tapped 0.750-16 UNF-2B to channel leakage oil back to tank. Internal seals are protected by limiting case pressure to 0.69 bar (10 psi). Drive torque is transmitted through a 6.35 mm (0.250 in) shaft key, and continuous service is permitted up to 65 °C (150 °F) oil temperature. The complete assembly weighs 11.8 kg (26 lb), which allows one person to handle it during installation or maintenance.
