Submersible drainage pumps
jacket cooled
for clear water and drainage water.

H 501 - H 511
Application
HOMA H 501 – H 508 are wear resistant submersible drainage pumps for
pumping clear water or drainage water
with abrasive sand or mud additives.
They are used to pump surface water
from sumps, subways and building
sites, for supply of industrial water,
applications on board ships etc. The
water jacket cooled motor with the top
discharge protects the motor against
overheating even during sip operation.
DIN EN 12050-2: Conformity and
design approved and controlled by LGA,
certificate No. 0220119.
Installation: Transportable or permanent. Models with float switch control
for automatic pump operation, depending on liquid level in the sump.
Pumped liquid: Clear water or
drainage water with abrasive (e.g. sand)
solids. Max. liquid temperature: 35°C,
short term up to 60°C.
Operation: Intermittent.
Design
Fully submersible, compact integrated
motor-pump unit consisting of:
Pump: Single stage centrifugal
pump with vertical discharge.
Impeller: Open multi-channel impeller, spherical clearance 10 mm.
Motor: Fully submersible, pressure
tight electric motor, oil-filled. Insulation class F. Motor protection IP 68.
Cable connection chamber totally isolated from motor housing. All 1 phase
models with thermal sensors embedded in motor winding.
Cablel:
Model W: H07RN-F3G1
Model D: H07RN-F4G1
Model H508W: H07RN-F4G1
Model H508WA: H07RN-F5G1
Model H511: H07RN-F4G1,5
Shaft/Bearing: Large diameter
stainless steel rotor shaft, pre-lubricated
bearings.
Seals: Combination of mechanical
seals with lip seal.
