3. General description

3.1. Application

Pump is suitable for pumping sewage, effluents, sludge
and surface water. The pumps are used for installations in
public and private sector, trade and industry.
The pumps can convey abrasive medium as surface wa-
ter. For highly abrasive content, such as concrete-gravel
and sand in the medium, it is necessary to protect the im-
peller and pump housing against excessive abrasion or to
shorten the maintenance interval. Before the pumping of
chemically aggressive liquids, the resistance of the pump
materials must be checked.
The pumps are available in high quality materials of all
components (Stainless steel, bronze). Use in sip opera-
tion is not permitted. According to the type of installation
and motor cooling, the machine must be submerged in
pumped liquid at least up to the top edge of the pump or
motor housing.
The motor housing must always be completely sub-
mersed for wet installation without a water jacket.
The temperature of the conveyed medium may be up to
40 °C, or up to 60 °C for a short period. The maximum
density of the medium is 1040 kg/m³ and the pH may
be from 6 – 11. However, the pH alone only serves as a
guideline. In any case, alongside the composition of the
medium, the durability of the pump must be requested
from the manufacturer. Depending on the composition, it
may be necessary to use special sealing materials.

3.2. Types of use

The motors are designed for continuous operation (S1),
maximum 15 starts per hour.
The hydraulic is designed for permanent operation, e.g.
supply of industrial water.

3.3. Construction

The pump consists of the motor and the pump housing
as well as the impeller with cutter system which belongs
to it. All important parts of the pump are characterized by
generous dimensioning.
