The Samoa PumpMaster 4 PM4 3:1 HV-L Air Operated Oil Pump is a high-performance pneumatic piston pump designed for dispensing lubricants from 205 litre (55 gallon) drums in medium-sized industrial and workshop lubrication systems. Built for reliability and efficiency, this pump delivers medium pressure with high volume output, making it ideal for professional oil transfer and dispensing applications. Part of the Samoa PumpMaster 4 (PM4) series, the pump features a double acting pneumatic piston design, ensuring smooth and continuous lubricant flow when connected to a compressed air supply. The 3:1 pressure ratio provides consistent performance when dispensing oils and lubricants in automotive service centres, industrial lubrication systems, and maintenance facilities. The pump includes a height-adjustable 2 inch BSP (M) bung adaptor, allowing secure mounting on 205 litre drums or lubricant storage tanks. A built-in port for an optional pressure relief valve (PN 609 007) enhances system safety when operating in pressurised fluid installations. Designed for efficient operation, the pump delivers reliable lubricant flow with low air consumption, providing an effective solution for workshop lubrication systems and industrial fluid management.
