Rotor Pump With Water-proff Cover
We are a world-leading technology-based enterprise
focus on R&D and manufactures non-Newtonian fluid conveying equipment. We
specialize in rotary pumps, homogeneous pumps and grinding pumps. We have
obtained 11 invention Patents and 46 practical patents, and won many national honorary
titles.
Twin-rotor
lobe pump are multi-functional and bi-directional positive displacement pumps,
produced with fine technology. These products use synchronic rotors, driven by
a pair of synchronic gears in the gear box. Transmitted by the main shaft and
the sub-shaft. The rotors move synchronically in counter-clockwise a
directions, which, consequently, varies the pump capacity and builds up high
vacuum capacity and emission pressure. It is particularly suitable to pump
sanitary medium, high-corrosive and high-viscous medium.
Rotor
pump with water-proff cover: The pump is equipped with a detachable protective
cover for the whole machine, and the material is S.S., it can protect the
motor, coupling and other parts from corrosion during on-site cleaning.
In
the past 30 years, we dedicate to provide the scientific and professional
solutions in fluid field. In the field of complex fluid transportation, our
company's R&D technology, manufacturing technology, application technology is
at the leading position in the world.
Durrex pumps can be widely used in food, consumer chemical, refined
chemical, paper making, chemical fiber, pharmaceuticals, coating, etc. We will
continue to focus on scientific research and innovation, improve the level of
precision manufacturing, and continuously promote the intelligent development of
fluid transportation industry, to create greater value for global users
