I. Overview

WFB Series self-priming pumps with no seal offer multiple functions such as temperature and pressure resistance, "drainage," and "self-priming." Currently, we produce a series of complete units in various materials including 321, 304, 316, 316L, A3, and PP (reinforced polypropylene), with five different designs and over a thousand specifications. Widely applicable in industries like electronics, electricity, chemicals, metallurgy, food, electroplating, firefighting, municipal, water purification, national defense, textile dyeing, mining, and civil construction, these pumps have received high praise from users.

II. Advantages

1. Utilizing the "Chain Type Multi-Surface Centrifugal Seal Device for Pumps," this innovation has replaced traditional packing, gasket, and mechanical seals in water pumps, significantly reducing occurrences of "leakage, spilling, dripping, and seeping."

2. The sealing device experiences minimal friction during operation, resulting in a lifespan that is over 10 times longer than that of similar products.

3. Transplanted vacuum pump principle, stable and reliable self-priming performance, utilizing "electric air control valve" to achieve "self-priming by guiding the flow."

4. Low vibration, low noise, flexible movement, easy disassembly, and simple installation without the need for footings.

5. Features self-control capability, compatible with automation systems.
