1. Delivery various medium smoothly without any disturbing and pulsation. There are medium to be pumped through out in the working elements as sealing liquid which guaranteed by the construction of pump casing. All of the pump possess high self priming ability and can deliver the liquid mixed with gas or air.
2. The high suction performance, i.e. very low NPSHr was guaranteed by the special    design of pump.
3. Adopted the external bearing which lubricated individually, so can deliver various non-lubrication medium.
4. Adopted synchronous gear, there is no metallic contact between rotating parts, there is no dangerous even dry running in a short time.
5. Various construction completely such as horizontal, vertical and casing with liner, and so on. The pump can handle various clean liquid without solid grain, low or high viscosity medium, even can deliver some
corrosive medium with a correct material selection.

>>>PERFORMANCE RANGE

1. Handling various medium without solid.
2. viscosity 1500cst the viscosity can reach up to 300000cst when reduced the speed.
3. Pressure range 4.0MPa
4. Capacity range 1-2000m3/h
5. Temperature range -15 -280

>>>APPLICATION
