WFB Sealless Self-Priming Pump

WFB Sealless Self-Priming Pump

The WFB Type Sealless and Leak-Free Self-Control Self-Priming Pump eliminates the mechanical shaft seal entirely, using a hermetically sealed magnetic drive or canned motor design. This ensures zero leakage — critical for hazardous, toxic, or volatile liquids where even minor leakage poses safety or environmental risks.

The self-priming capability allows installation above the liquid source without flooding, with automatic re-priming after accidental dry running. The pump includes a self-control mechanism that protects against dry running damage.

Suitable for petroleum products, solvent chemicals, acids, alkalis, liquefied gases, and other hazardous media. Construction materials available in PP, PVDF, SS316L, Hastelloy, and other corrosion-resistant alloys.
