The Samoa PumpMaster 4 PM4 3:1 Stainless Steel Pneumatic Piston Pump is a high-performance air operated pump designed for transferring and dispensing corrosive and chemical fluids in medium-sized industrial installations. Built with stainless steel construction, the pump offers excellent resistance to corrosion, making it ideal for demanding chemical handling and industrial fluid transfer applications.

Part of the Samoa PumpMaster 4 (PM4) series, this double acting pneumatic piston pump delivers medium pressure with high fluid volume output, ensuring efficient and consistent dispensing performance when powered by compressed air. The 3:1 pressure ratio provides reliable fluid delivery for industrial fluid transfer systems.

The pump includes a height-adjustable 2 inch BSP (M) bung adaptor, allowing secure mounting on drums or tanks for stable installation. A built-in port for an optional pressure relief valve (PN 609 007) provides additional safety when used in pressurised fluid systems.

For drum installations, the pump can be paired with the recommended PVC suction tube PN 331 110.002, enabling direct mounting on 205 litre drums for efficient fluid extraction.

The Samoa PM4 stainless steel pump is ideal for chemical processing plants, industrial lubrication systems, fluid transfer stations, and workshop fluid management systems requiring durable pneumatic pumping equipment.
