China Acid-Proof Explosion-Proof Self-Priming Water Pump

Excellent corrosion resistance: The material of the flow end is CFRPP FRPP CPVC PVDF, respectively. Both have excellent corrosion resistance and can be used to transport most chemical liquids including strong acid and alkali.
1. Specially designed cooling for shaft seal. The built-in Teflon bellow seal features automatic cooling performance without use of circulated cooling hose.
2. Vacuum self priming design. Extremely powerful self priming force. Built with a choke valve fully prevents liquid back-flow in the pump.
3. Superior corrosion-resistant performance. Material - CFRPP FRPP CPVC PVDF
4. To prevent foreign matter from suction, foot valve should be installed in the inlet. To prevent from immediate backflow, check valve should be installed in the outlet. Backflow results in pump's body damage and dry-running also damages to the pump.
5. Depending on customers' needs, cooling circulated tube can be assembled. The liquid inside of pump circulates and cools down the shaft seal the when dry-running.
