The Samoa PumpMaster 4 PM4 5:1/L Air Operated Oil Pump is a powerful pneumatic piston pump designed for dispensing lubricants from 205 litre (55 gallon) drums in medium to large industrial lubrication installations. Built for professional performance, this pump delivers medium pressure with reliable oil flow, making it suitable for lubrication systems with multiple dispensing points operating simultaneously. Part of the Samoa PumpMaster 4 (PM4) series, the pump features a double acting pneumatic piston design, ensuring smooth and continuous lubricant delivery when powered by compressed air. The 5:1 pressure ratio allows efficient dispensing of oils and lubricants across larger workshop lubrication systems and service bays. The pump includes a height-adjustable 2 inch BSP (M) bung adaptor, allowing secure installation on 205 litre drums or lubricant tanks. A built-in port for an optional pressure relief valve (PN 609 007) provides additional safety when used in pressurised lubrication systems. Optimised for efficient performance, the pump operates with low air consumption at 6 bar (87 psi) while delivering reliable oil transfer across multiple outlets. The Samoa PumpMaster 4 5:1/L oil pump is ideal for automotive workshops, fleet maintenance centres, industrial lubrication systems, and multi-point oil dispensing installations.
