The PPS (Polyphenylene sulfide) and glass fiber construction resists a broad range of chemicals and is unaffected by moisture or immersion in water. Our pump is light and impervious to oxidation and corrosion. Custom design low resistance radiator allows higher flow rate, heat exchange efficiency and provides unmatched cooling performance. FEP tubing makes it durable yet flexible. Sleeved tubing on the exterior to give it a premium look.
