Product Information
- Name : WFB Fluorine-alloy Seal-free Automatic Control Self-priming Pump | Vertical PVDF Anti-corrosion Self-priming Chemical Pump
- SKU : BLT-200
- Category : centrifugal-pumps
WFB fluorine-alloy seal-free self-priming pump, vertical seal-less self-priming chemical pump built with fluoroplastic alloy wetted parts, eliminates mechanical-seal-related fluid leakage. Equipped with auxiliary impeller, electric control valve and stop check valve, this vertically integrated pump features compact layout and requires no foot valve. It can pair with wheeled carts for easy relocation, and works well for corrosive-fluid transfer in chemical, wastewater treatment and metallurgical operations.

Working Principle
A certain volume of liquid stays inside pump casing before startup. The rotating main impeller agitates and mixes air with process liquid. The air-liquid mixture flows into the separation chamber, where air vents upward while liquid flows back toward impeller inlet. This cycle continues until suction line air is fully evacuated and self-priming is achieved. Liquid remains trapped inside pump chamber after shutdown, so no re-priming is needed for subsequent starts. The seal-less auxiliary-impeller dynamic sealing design handles corrosive media carrying minor solid particles.
