NYP2.3 Gear Oil Pumps with CE Approved

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 industry,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:-10ºC-200ºC
  Proper medium viscosity:1.cSt-300.000cSt
2.Type of  structure(As fugure 1)
(1)Work principle
  Driving gear(out side rotor)with internal tooth drives the internal rotor and turn in same direction in the full closed pump body.The pump casing and crescent of the front cover separate 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 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 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 adopt.
  When the delivered medium is easy crysrallinic.We can design rhe 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 baseplate.The direction way is belt wheel driving or coupling driving.
  The direction of rotation is clockwise rotation from coupling end.
3.Vdvantages
  (1)Steady delivery without pulsation,little cibration and noise.
  (2)Out standing self-priming ability.
   (3)The pump can deliver the varied corrosion mediums if the proper material of parts selected.In addition,the working temperature can reach 200ºC.
  (4)The same rotary directiom of internal rotor and ourside 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 delicer high viscosity medium.
