Vickers 421238 Cartridge Kit

The Vickers 421238 cartridge kit is a replacement cartridge assembly for Vickers hydraulic vane pumps, engineered to perform internal pump rebuilds and restore hydraulic flow and pressure performance in hydraulic power systems. Manufactured by Vickers / Eaton Vickers, this kit includes rotor, vanes, cam ring, side plates, and associated wear components (contents may vary by application) and is designed for installation during pump maintenance and rebuilds in industrial and mobile equipment. It is commonly installed in hydraulic power units across manufacturing, including hydraulic presses, injection molding machines, machine tools, conveyor systems, and other industrial machinery where vane pumps require rebuilding to recover flow, pressure, and overall hydraulic reliability. The kit is suitable for Vickers hydraulic vane pumps and uses hydraulic oil as the compatible media, serving preventive maintenance and pump repair applications.
