Pressure Medium: Oil Specification: GB/T 19001--2000 idt ISO 9001-2000; CE HS Code: 8413602990 Trademark: HENGNUO Origin: Cangzhou 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 vicosity because of special structure and selected different pump's materials.
Proper medium temperature: -10 centrigrade~200 centrigrade.
Proper medium viscosity: 1.0cSt~300, 000cSt

Work principle
Driving gear (outside rotor)with internal tooth drives the internal rotor and turns in same direction in the full closed pump body. The inlet from the outlet. When it turns, negative pressure formed at the suction port, the liquid inlet and being take to the outlet by rotor, then the liquid is impelled from the discharge port and the gears mesh. The transportation of liquid finished.

ADVANTAGES
1)Steady edlivery without pulsation, little vibration and noise.
2)Outstanding self-priming abitity.
3)The pump can deliver the varied corrosion mediums if the proper material of poarts selected. In addition, the working temperature can reach 200 centrigrade.
4)The same rotary direction of internal rotor and outside rotor results in little wear and long loperation life.
5)The pump's flow capacity can be changed through adjusting the speed.
6)It's specilly suited to deliver high visc medium.
