Technical Specifications

Compatible Applications

This pneumatic double diaphragm pump suits industrial fluid transfer in automotive, marine, and manufacturing settings, pumping viscous materials, abrasives, or slurries up to 120 PSI without electricity for safe hazardous locations. Its aluminum construction resists corrosion, ideal for oil, detergents, and hydraulic fluid handling in workshops or plants.

Maintenance Tips

Lubricate the air inlet sparingly every 500 hours if needed, despite lube-free design, and inspect diaphragms regularly for wear to sustain peak performance. The modular design simplifies repairs, with external air valve access cutting service time significantly.
