NYP high viscosity fluids internal gear pump

NYP internal gear pump is a kind of new positive displacement pump and is designed according to the different requirements from petroleum, chemical industry, paint, medicine, foodstuff and so on.

NYP internal gear pump is widely applied to various mediums with different property and viscosity because of special structure and different pump materials. NYP internal gear pump is Especially suitable for high viscosity medium and fluid transport, such as resin, hot melt adhesive, heavy oil, asphalt, glue and other high viscosity medium.

Medium viscosity:1.0cst to 300,000CST.   Temperature:10DegC-200DegC.

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 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 transportation of liquids is finished.

NYP Gear pump is mainly composed of internal rotor, outside rotor, shaft, pump  casing, front cover, seal, bearing etc.

The pump seal 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 crystallized, 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 safety valve.

The pump set is composed of the pump and motor and base plate. The driving way can be belt wheel or shaft coupling driving.

The direction of rotation is clockwise viewed from coupling end. Seen from the electric motor to the pump, it rotates clockwise, enters from the right side and exits from the upper side.
