(1) Pumps will not be overheated and are discharged without harmful gas.

(2) Electric sparks will not be generated.

(3) It is not easy to be blocked.

(4) The minimum stirring of the material is suitable for the transmission of unstable substances.

(5) The flow can be adjusted, and the throttle valve can be installed at the outlet exit to adjust the flow.

(6) It has the function of self -priming.

(7) It can run empty without danger.

(8) Diving work.

(9) The fluid that can be transported is extremely wide, from low viscosity to high viscosity, and obtained viscosity from corrosiveness.

(10) There are no complex control systems, without cables, fuses, etc.

(11) Small volume and light weight, easy to move.

(12) The maintenance is simple without lubrication, and it will not contaminate the working environment due to dripping.

(13) Pumps can always remain efficient and will not be reduced due to wear.

(14) 100 % energy use, when the exit is closed, the pump is automatically stopped.

(15) There is no dynamic seal, and the maintenance is easy to avoid leakage. There is no death point at work.
