3. General description
3.1. Application
HOMA pumps convey domestic, municipal and industri-
al waste water, faeces and sludge, also with high solid
and fibre content, as well as drainage water of all kinds.
The pumps can be used in small residential buildings, in-
dustrial buildings or large pumping stations and sewage
treatment plants.
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 operation 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 mo-
tor housing must always be completely submersed 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 which belongs to it. All important
parts of the pump are characterized by generous dimen-
sioning.
