Features and Benefits
- Approved to external ATEX standards Ex II 2G IIC T4 and Ex II 2G IIB T4, which enables use in hazardous environments.
Supplied with ultragrade 19 oil, NW25 O-ring and centering ring.
An oil pressure system lubricates the pump shaft bearing surfaces and rotor sealing faces. The pump has an oil distribution valve which prevents discharge of oil to the pump interior (suckback) after the pump stops. The pumping chambers are air-tight, so this arrangement prevents oil suckback unless the gas ballast valve is open.
You can inspect the level and condition of oil in the oil box reservoir through the oil sight-glass. An oil filler-plug is fitted to the top of the oil box. The pump has two oil drain-plugs to allow either gravity oil drain or pressure oil drain.
