Brief Introduction:
  NYP series internal gear pump is a kind of new positive displacement pump,  and is designed according to the different fields, requirements of petroleum, chemical industry, paint, medicine, foodstuff and so on. It widely applies  to a variety of mediums with different property and viscodity because of special structure and selected different pump's materials.
  Proper medium temperature:-10ºC~200ºC
  Proper medium viscosity:1.0cSt~300.000cSt

Type of structure
(1)Work Principle
  Driving gear(out side rotor) with internal tooth drives the internal rotor and turns in same direction in the full closed pump body. The pump casing and crescent of the front cover separare the inlet from the out let. When it turns negative pressure formed at the suction port, the liquid inhaled and being take to the outlet  by rotor, then the liquid is expelled from the discharge port as the gears mesh. The transportation of liquid finished.
(2)Structure Feature
  As figure I. The pumps are mainly composed of internal rotor, outside rotor, shaft, pump casing, front cover, seal, bearing ect. The pump, seal adopts packing seal or mechanical seal. When the delivered medium is high temperature, high visocity or strong corrosion, packing seal should be adopted.
  When the delivered medium is easy crystallinic, We can design the heat preservation jacket in pump casing and front cover in order to melt the medium with steam when working. The pump can be also fitted with the salty valve.
  The pump set is composed of the pump, motor and baseplare. The direction way is belt wheel driving or coupling driving.
  The direction of rotation is clockwise rotation from coupling end.

Advantages:
  (1).Sready delivery without pulsation, little vibration and noise.
  (2).Out standing self-priminh ability.
  (3)The pump can deliver the varied corrosion mediums if the proper material of part selected in addition, the working temperature can reach 200ºC
  (4)The same rotary direction of internal rotor and outside rotor results in little wear and long operation life.
  (5)The pump;s flow capacity can be changed through adjusting the speed.
  (6)It's specially suited to deliver high viscosity medium.
