7.2.1 CVD2 – Basic unit
The chemical is dosed by two diaphragm pumps. The convey-
ing capacities of the pump can be adjusted at the manual
stroke length adjustment. Depending on the design of the dos-
ing pump, an additional automatic dosing is possible via pulse
or analogue signals.
The piping on the pressure side consists of a taper seat non-
return valve and a ball valve as end connection. The pumps
are protected against overpressure by an overflow valve. A
drain ball valve for evacuation/pressure relief is fitted in the
pressure pipe.
The pipes on the pressure and the suction side of the basic
unit are not connected with each other.
The pumps and the corresponding fittings are mounted on a
wall mounting plate with collecting basin.
