The Samoa PM45-03MS Air Operated Oil Pump Pumpmaster 45 Series (3:1 Ratio) Stub Mount is a high-volume pneumatic piston pump designed for large volume oil transfer applications in workshop and industrial environments.

Part of the PM45 series, this double acting air operated pump delivers medium pressure with very high flow output, making it ideal for applications where moving large quantities of oil quickly is more important than high pressure.

With a 3:1 pressure ratio, the pump is optimised for bulk oil transfer, ensuring fast and efficient delivery across large systems.

This stub-mounted configuration allows flexible integration into customised setups, tanks, or existing lubrication systems. The pump is designed for flange mounting, providing secure installation in fixed systems.

For added safety and system control, the pump includes a built-in port for an optional pressure relief valve (PN 609 007).

Built for durability and continuous operation, this oil pump is ideal for industrial facilities, fleet maintenance operations, and workshops requiring efficient, high-volume oil transfer.
