The 25VTBS12A 2203BB 22R pump belongs to the Vickers Vane Pumps series and supplies hydraulic flow for automated equipment. Its displacement is 40.2 cm³/rev (2.45 in³/rev), setting the fluid volume moved with each revolution. A maximum pressure rating of 210 bar (3000 psi) permits operation in medium-pressure circuits. Right-hand (clockwise) rotation aligns with common industrial drive shafts. An SAE B 101-2 front mounting flange lets the unit bolt directly to standard motor faces, while an SAE 4-bolt flange port connection provides a rigid, leak-resistant interface for piping. The 25.40 mm (1.000 in) shaft diameter accepts widely used couplings, and a 6.35 mm square by 50.8 mm key secures torque transfer without slippage.
The pump tolerates up to 402 Nm (3560 lb-in) of input shaft torque, preventing drive components from overstressing internal parts. When used in a tandem arrangement, the thru-drive can pass 316 Nm (2800 lb-in) through connection B, aided by an included SAE splined coupling that simplifies alignment. An outlet positioned 90° counter-clockwise from the inlet eases hose routing in confined manifolds. A double shaft seal keeps internal oil from escaping and blocks external contaminants. At maximum speed the unit delivers 88.5 l/min (23 US gpm) and requires about 41.0 kW (55 hp) of input power, figures that guide motor and cooler sizing. The assembled weight is 19.5 kg (43 lb), allowing one person to handle installation in most service scenarios.
