1 Description
The ECODRY plus is an eight-stage Roots pump. It is of the dry compressing
type and capable of evacuating chambers down to the medium vacuum
range.
The pump is connected to a single-phase supply using a mains power cable
and is powered via a built-in electronic drive unit. It is air-cooled. Bearings
and gears are lubricated using PFPE. The pump is therefore maintenance-
free from the customer’s perspective.
1.1 Supplied Equipment
The pump is delivered ready for use, except from a power cable. Inlet and
exhaust flanges are closed. The scope of delivery includes:
■
2 centering rings, 2 clamping rings, 2 blank flanges for the inlet and
exhaust flanges
■
D-sub 9-pin jumper for manual operation of the pump.
