The Qeehua vertical centrifugal pump body is made of corrosion-resistant plastics (PP, PVDF, GFRPP, CFRETFE).
The pump features a one-piece molding design to prevent leakage, and incorporates a self-developed protective device to prevent damage from dry running, extending its service life to up to 10 years.
The Vapor Seal design prevents corrosive gases from evaporating chemicals from entering the motor, making it ideal for various corrosion-resistant applications.

Vertical In-tank Pump - QHA
√ Double-convex shaft seal corrosion protection: The unique double-convex seal structure of the impeller and shaft is specifically designed to solve the problem of easy corrosion of the shaft.
√ Highly corrosive chemical solution circulation, multi-element voltage and frequency matching requirements.

Out-of-tank Pump - QHD
√ Maximum power, patented anti-bubble design: reduces bubbles by over 90%. Specifically designed for external use (can be modified for internal/in-tank use).
√ Metal/PCB etching, coating, spray tower (high-requirement fluids).
