SAMOA PM3 Air Operated Grease Pump – 55:1 Ratio, 540 g/min, Spain - 409200

High-Flow 540 g/min SAMOA Air Grease Pump

Maintaining heavy mobile fleets and agricultural machinery demands continuous, high-pressure lubrication without bottlenecks. The SAMOA 409200 (PumpMaster 3) steps into this critical role as a highly efficient pneumatic piston grease pump, built specifically to tackle highly viscous fluids. Utilizing an impressive 55:1 pressure ratio, it effectively amplifies standard shop air to generate a staggering maximum outlet pressure of 550 bar (7975 psi). This sheer mechanical force easily pushes thick NLGI-2 grease through long hoses or into stubborn fittings, achieving a rapid maximum free flow delivery of 540 g/min.

Sized perfectly for bulk industrial operations, this unit features a long 920 mm (36") carbon steel pump tube tailored to fit standard 185 kg (400 lb) open-head drums. Despite its heavy-duty output and rugged one-piece zinc mazak air motor housing, the total unit weighs an incredibly light 4.8 kg, enabling technicians to swap out heavy drums quickly and maneuver mobile greasing units with zero hassle. At the heart of its reliable performance lies a double-acting piston and an advanced chop-check inlet that mechanically pulls thick grease into the pump. Manufactured entirely in Spain and operating flawlessly within a wide air pressure range of 1.5 to 10 bar, it guarantees enduring performance in the harshest workshop environments.

Key Features & Benefits:

• Spanish Engineering: Manufactured in Spain, strictly adhering to high European quality and safety standards for industrial lubrication equipment.
• High-Pressure Ratio: Features a massive 55:1 ratio capable of generating up to 550 bar (7975 psi), ideal for pushing thick grease into stubborn fittings.
• Large Drum Compatibility: The 920 mm (36") tube is perfectly sized for standard 185 kg (400 lb) open-head grease drums.
• High Efficiency: Delivers a maximum free flow of 540 g/min (and 300 g/min standard), ensuring fast lubrication cycles even in heavy-duty applications.
• Double-Acting Piston Design: Ensures a continuous and balanced flow of grease on both the up and down strokes, significantly reducing pulsation.
• Chop-Check Inlet: Specifically designed to handle heavy, viscous greases (up to NLGI-2) by mechanically "chopping" and pulling the grease into the tube.
• Lightweight Maneuverability: Weighing only 4.8 kg, it is exceptionally easy to move and install when changing out empty drums.
• Wide Air Range: Operates effectively on standard shop air from 1.5 to 10 bar (21 to 145 psi), allowing flexibility across different pneumatic setups.
• Integral Foot Valve Filter: Includes a built-in filter at the bottom of the pump tube to protect internal mechanisms from dirt and drum contaminants.
• Rugged Construction: Built with a durable one-piece zinc mazak air motor housing, a carbon steel pump tube, and wetted parts made of NBR and PTFE.
