SAMOA PM3 Air Operated Grease Pump – 55:1 Ratio, 540 g/min, Spain - 407200

SAMOA 50kg Drum Pneumatic Grease Pump

Fast-paced fleet maintenance and heavy-duty agriculture operations require lubrication tools that seamlessly blend raw power with compact agility. The SAMOA 407200 (PumpMaster 3) delivers precisely that, functioning as a high-tier PNEUMATIC PISTON GREASE PUMP tailored perfectly for medium-sized fluid containers. By amplifying standard shop air through a massive 55:1 pressure ratio, this Spanish-built unit forces heavy NLGI-2 fluids through restricted fittings at an impressive maximum outlet pressure of 550 bar (7975 psi). This formidable mechanical output translates directly into faster service times, achieving a rapid maximum free flow delivery of 540 g/min.

Form factor is where this specific model truly excels on the shop floor. It utilizes a custom 725 mm (28.5") carbon steel pump tube engineered to precisely reach the bottom of standard 50 kg (120 lb) open-head drums without creating unnecessary overhead clearance issues. Because the entire unit weighs an ultra-light 4.3 kg, service technicians can effortlessly swap it between drums or mount it inside mobile service trucks. Internally, a double-acting piston and an aggressive chop-check inlet work together to mechanically pull thick fluids upwards, ensuring a continuous, non-pulsating flow that keeps heavy machinery running at peak performance.

Key Features & Benefits:

• Optimized for 50 kg Drums: Features a custom 725 mm (28.5") tube length designed to reach the bottom of medium containers without excess height.
• High-Pressure Ratio: Capable of generating up to 550 bar (7975 psi), ideal for pushing thick grease into stubborn industrial fittings.
• High Efficiency Flow: Delivers a maximum free flow of 540 g/min, ensuring incredibly fast lubrication cycles even in heavy-duty applications.
• Double-Acting Piston Design: Ensures a continuous, balanced flow of grease on both the up and down strokes, drastically reducing pulsation.
• Chop-Check Inlet: Specifically designed to handle heavy, viscous greases (up to NLGI-2) by mechanically pulling the fluid into the pump tube.
• Compact & Lightweight: At only 4.3 kg, it is significantly easier to transport and swap between drums in fast-paced workshop environments.
• Wide Air Range: Operates effectively on standard shop air anywhere from 1.5 to 10 bar (21.75 to 145 psi), allowing massive flexibility.
• Integral Foot Valve Filter: Includes a built-in filter at the bottom of the pump tube to protect internal mechanisms from drum contaminants.
• Rugged Construction: Features a one-piece zinc mazak air motor housing and a carbon steel pump tube for maximum structural integrity.
• Spanish Engineering: Manufactured in Spain, adhering strictly to high European quality and safety standards for industrial equipment.
