3. General description
3.1. Use
The C 140WA type pump is a single-stage transportable
centrifugal pump, suitable for conveying rainwater and
lightly contaminated water containing solids with a diam-
eter of up to 10 mm. Its areas of application include cellar
drainage, keeping pits and shafts dry, emptying collecting
basins, as an emergency pump in the event of flooding, as
a circulation pump for garden ponds etc.
Removing the suction strainer allows a flat surface to be
drained to a level of 5 mm.
The CH140 WA type pump is suitable for the disposal of
chemical aggressive drainage water e. g. salt water
(up to 15%) from water softening devices and brine from
condensing boilers. For chemically aggressive media a
consultation is necessary because the resistance of the
pump materials must be checked.
Substances that grind like emery or others that attack its
basic material may destroy the pump. This pump is not
suitable for use on media containing admixtures of abra-
sive dirt, sand, sludge or clay.
The temperature of the conveyed liquid may go up to
35°C. The C140 WA type may go up to a maximum of
60°C for a short time. The maximum density of the con-
veyed liquid is 1040 kg/m³.
3.2. Types of use
The motor is designed for the S1 (continuous) mode of
operation, with a max. switching rate of 15 switching op-
erations / hour. The hydraulics are suitable for permanent
continuous operation.
3.3. Construction
The fully submersible unit consists of the motor, the pump
housing and the appropriate blade wheel. All important
components are generously dimensioned.

3.3.2. Motor
The motor consists of a stator and the motor shaft with
the rotor set. The lead for supplying power is designed for
the maximum mechanical power in accordance with the
characteristic curve or data plate of the pump. The cable
entries and the lead are sealed watertight against the con-
veyed medium. The shaft bearings are robust, maintenan-
ce-free and permanently greased roller bearings.
