2W.W Sealed Twin Screw Pump

 Sealed Twin Screw Pump

Parameters
Maximum pressure: 4.0MPa
Range of displacement: 1~1000m3/h
Range of temperature : -20~120℃
Viscosity : 1~3000mm2/s

Application
The twin pumps can be used marine vessels to wash the decks and to dispose waste water, or engine lubrication pump, fuel pumps
The twin screw pump can transfer chemicals as polymer, wax, paintings, inks, emulsion glue, and greases,
Oils can be transferred as crude oil, so the twin screw pump always as oil loading pump and discharging pump.
The pump can transfer food like honey, syrup, food olds, milk, soft drinks, liquor, wine, beer and other liquids of food
