Product Information
- Name : WFB Sealless Self‑Controlled Self‑Priming Pump | Zero‑Leakage Vertical Chemical Self‑Priming Pump
- SKU : BLT-193
- Category : centrifugal-pumps
The WFB vertical sealless self‑priming pump consists of pump casing, main impeller, auxiliary impeller, pump shaft, motor bracket, electric control valve and stop check valve. It adopts gas‑liquid mixing self‑priming structure. Eliminating mechanical seals, it prevents fluid leakage for corrosive chemical media.

Working Principle
Pre‑store liquid inside pump casing before startup. The rotating impeller mixes suction‑line air with liquid and sends the mixture to the gas‑liquid separation chamber. Air is vented out while liquid recirculates. Continuous circulation exhausts pipeline air to achieve self‑priming. The stop check valve keeps liquid in pump cavity for restart without refilling.
Application Fields
Fine Chemicals: Convey acids, alkalis and salt solutions for process circulation.
Wastewater Treatment: Wastewater lifting and circulating service.
Metallurgy & Pharmacy: Transfer toxic and corrosive process fluids.
General Industry: Handle media with minor solid particles under frequent start‑stop conditions.
