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 widly applies to a variety of mediums with different property and viscosity because of special structure and selected different pumps materials.

Proper medium temperature : -10℃~200℃

Proper medium viscosity :1.0cSt~300,000 cSt 

Type of structure :

Work principle

Driving gear (outside  rotor ) with internal tooth drives the internal rotor and turns in the same direction in the full closed pump body .The pump casing and crescent of the front cover separate the inlet from the outlet . 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 transport-tation of liquid finished .

Structure  Feature

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 visc or strong corrosion , packing seal should be adopted.

When the delivered medium is ease crystallinic , we can design the heat preservation jacket in the pump casing and front cover in order to melt the medium with steam when working . The pump can be also fitted with the safty valve .

The pump set is composed of the pump , motor and baseplate . the direction way is belt wheel driving or coupling driving .

The direction of rotation is clockwise vievoed from coupling end.

Advantages

Steady delivery without pulsation , little vibration and noise.

Outstanding self-priming abitity .

The pump can deliver the varied corrosion mediums if the proper material of parts selected . In addition , the working temperature can reach 200℃

The same rotary direction of internal rotor and outside rotor results in little wear and long operation life .

The pump’s flow capacity can be changed through adjusting the speed .

It’s suited to deliver high visc medium .
