Engineering Plastic diaphragm pump Performance Summary

QBY Engineering Plastic diaphragm pump not only can exhaust the flow liquid,but also can convey some uneasy flowed medium,with the merits of self-pumping pump,diving pump,shield pump,slurry pump and impurity pump etc:

Engineering Plastic diaphragm pump Working principle

There installs each diaphragm in both aligned working cavities(A) &(B),which can be connected tonether with a central coupling lever.The compression air enters the air distribution valve from the air entrance of the pump,draw the compression air into one cavity through the air distibution mechanism,push out the diaphragm movement in the cavity.The gas in another cavity will be drained.Once reaching the stroke terminal,the air distribution mechanism will automatically draw the compression air into another working cavity,push out the diaphragm to move towards the opposite direction,so as to let the both diaphragms continuously reciprocate motion in synchronism. The compression air enters the air distribution valve from(E)shown as the diagram,let the diaphragm piece move towards the right direction.And the suction force in(A)chamber lets the medium flow into from(C)entrance,push out the ball valve(2)to enter(A)chamber,the ball valve(4)will be locked due to the suction force;The medium in(B)chamber will be pressed,push out the ball valve(3)to flow out from the exit(D).Meanwhile,let the ball valve(1)close,prevent backflow.Such movement in circles will let the medium uninterruptedly suck from(C)entrance and drain feom(D)exit.

Engineering Plastic diaphragm pump Main usage

  1. The pump can suck the peanut,pickles,tomato slurry,red sausage,chocolate,hops and syrup etc.
  2. The pump can suck the paint,pigment,glue and adhesive etc.
  3. The pump can suck various glazed slurries of tile,porcelain,brick and chinaware etc.
  4. The pump can suck various grinding materals,corrosive agent and clean the oil dirt etc.
  5. The pump can suck various toxin and flammable or volatility liquid etc.
  6. The pump can suck various wedge water,cement slurry and mortar etc.
  7. The pump can suck various strong acid,alkali and corrosive liquid etc.
  8. It can be used as a front-step transmission device of the solid and liquid separation equipment.
