Product Description
Internal Gear Pump
1, 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 insustry, paint, medicine, foodstuff and so on. It widely applies to a variety of mediums with different property and viscosity because of special structure and selected different pump's materials.
Proper medium temperature: -10. C-200. C
Proper medium viscosity: 1.0cst-300, 000cst
2, structure
(1)working principle
Driving gear (outside rotor) with internal tooth drives the internal rotor and turns in same direction in the full closed pump body. The pump casting 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 taken to the outlet by rotor, then the liquid is expelled from the discharge port as the gears mesh. The transportation of the liquid finished
(2)Structure Feature
Component: Internal rotor, outside rotor, shaft, pump body, front cover, seal, bearing etc.
The seal of pump adopts packing seal or mechanical seal. When the delivered medium is high temperature, high viscosity or strong corrosion, packing seal should be adopted.
When the delivered medium is easy crystalline materials, we can design the heat preservation jacket in pump body and front cover in order to melt the medium with steam when working, the pump can be also fitted with the safety valve.
The pump set is composed of the pump, motor and base plate, the direction way is belt wheel driving or coupling driving.
The rotation direction is clockwise from motor end.
3, Advantage
(1)steady delivery without pulsation, little vibration and low noise
(2)outstanding self-priming ability
(3)the pump can deliver the varied corrosion medium if the pump parts selected proper materials. In addition the working temperature can reach max 200. C
