FEATURES

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.

4. Rear Cover, seal cover and base frame are one-piece injected without welding. Therefore, it makes
    repairing, assembling, and disassembling easier.

5. 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.
