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 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 com-
pletely 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 compo-
sition 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 20 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 gen-
erous dimensioning.
