High Performance
in Waste Water Pumping
HOMA submersible waste water andsewage pumps operate worldwide innumerous kinds of domestic, municipaland industrial applications. Decades ofexperience in the design and manufac-turing of submersible pumps plusuncompromising attention to quality inevery detail and strict monitoring ofproduction quality ensure the utmostreliability and long service life of allHOMA products.
Flexible system-components
for problem-free installation
HOMA combines efficiency, safety, highquality and robust design with a flexibili-ty that allows the individual optimizationof every project realization:
The reliability of fully
automatic operation
HOMA waste water pumping stationsfeature fully automatic control and moni-toring. Reliable liquid level control sys-tems of various types (float switch,pneumatic, ultrasound or electronic sys-tems) are available to secure reliablepump operation at minimum energyconsumption. All possible fault factorslike shaft seal condition, temperatures,moisture or power supply can be auto-matically monitored and transferred tovarious alarm systems.
Pumps for various types of applicationand installation, a complete program ofinstallation equipment including pipes,valves, pump pits from concrete orcomposite materials, electric controland monitoring systems. With thisrange HOMA can provide a tailor -madesolution for every waste water pump-ing application.

The right installation for every pump station Operating conditions
The motors are designed for continu-ous operating duty (S1) at maximum15 starts per hour. In addition to a fullysubmerged motor housing in wet wellinstallation, a jacket cooled motor-vari-ant is available for S1 operating with anon-fully submerged motor or for drywell installation.
Pumps with enclosed two-channelimpellers are designed for intermittentoperation, normally in automatic level-controlled wet or dry well sumpinstallations. They are also suitable forlimited continuous operation, as instorm water retention tanks, or forunlimited continuous operation, suchas industrial water supply.
T h e s o u r c e f o r e x t r a o p t i o n s a n d a p p l i c a t i o n s
Various challenges – individual solutions:HOMA submersible wastewater pumpsare designed for pumping sewage,sludge, effluents or surface water,including liquids containing a large pro-portion of solid or fibrous matter. They areinstalled in domestic, municipal, industrialand agricultural pumping applications.
For chemically aggressive liquids, specificcomponents like impellers, volutes orcomplete units are also available fromhigh-resistant materials like stainlesssteel, duplex or bronze.
Wet well installation with base stand
Submerged pump mountedon a ring base stand fortemporary, service oremergency operation.Discharge connectionwith pipe or hose.
Higher Performance
to meet every Challenge
Ranges and Models
All motors are also suitable for operatingwith frequency converter or soft starterdevice.
Explosion protection:
In addition to the standard version, allmotors are available explosion proofaccording to ATEX Ex II 2 G EEXd.
Dry well variant:
Besides the version for submerged ope-ration, all pumps are also available fordry well or non-submerged operation.Motor cooling is provided by a coolingjacket, using either the pumped liquid orexternal coolant circulation.
Hydraulic selection
Discharge and suction flange:
● DN 200● DN 250● DN 300● DN 400
Reducing adapters for different auto-coupling system and valve dimensionsare available.
Motor selection
Motor speed:
For the standard hydraulic ranges, themotors are designed with the followingspeeds:
● 1450 U/min = 4-pole
● 960 U/min = 6-pole
● 720 U/min = 8-pole
Voltages:
All specified data relate to an operatingvoltage of 400 V/3 Ph, 50 Hz. Differentvoltages are available on request.
Type of starting:
The motors are supplied as standardsuitable for Direct- or Star-Delta-Start.
Motor monitoring:
All motors are supplied with temperaturesensors in the winding, bi-metalic sen-sors (standard) or PTC sensors or PT 100(on request).● Motors for wet well installation
(without cooling jacket):As C-version (see pump type code) with oil chamber seal condition monitoring probe and moisture sensor in junction chamber)
● Motors with cooling jacket:Supplied as standard with oil chamber seal condition monitoring probe.
S-version additionally with moisture monitoring in the stator housing.Additional monitoring devices (e. g. bear-ing temperature) on request.
Submerged autocoupling guide tubesystem for automatic connection anddisconnection of the pump from thepipework from outside the sump. Allmaintenance or repair work can be doneoutside the sump. Back in operatingposition, the weight of the pump ensu-res leak-proof discharge connection.
Impeller spherical clearance:
The pumps are available with impellerspherical clearances from 100 mm to165 mm according to pump range.
