for chemically aggressive liquids.
Spherical clearance 10 mm.

CH 432, CH 436
Application

Performances

HOMA CH 432 and CH 436 stainless
steel submersible drainage pumps are
suitable for pumping corrosive, abrasive
or chemically aggressive liquids, drainage
water or chemicals containing soft solids
up to 10 mm diameter. They are used in
various domestic, industrial or municipal
applications.
DIN EN 12050-2: Conformity and
design approved and controlled by LGA,
certificate No. 0220119.
Installation: Transportable or
permanent.
Pumped liquid: Drainage water
with abrasive or chemically aggressive
contents, chemical liquids.
Chemical waste or effluent.
Max. liquid temperature: 40°C, short
term up to 60°C, for limitation to lower
temperatures see specific chemical resistance of used materials.
Technical Data
Operation: Permanent (S1).
Design
Fully submersible, compact integrated
motor-pump unit consisting of:
Pump: Single stage centrifugal pump
with horizontal discharge.
Impeller: Open multi-channel impeller,
spherical clearance 10 mm.
Motor: Fully submersible, pressure
tight electric motor. Insulation class H,
degree of protection IP 68. Thermal sensor embedded in the winding.
Cable: H07RN-F(PLUS)6G1,5
Model W: H07RN-F(PLUS)-4G1,5 with
cable protective hose and longitudinally
tight cable trumpet. Explosion proof
motors according to II G EEx d II BT4.
Shaft/Bearing: Large diameter stainless steel rotor shaft, pre-lubricated bearings.
Seals: Combination of mechanical
seal and lip seal (CH 432) respectively
2 mechanical seals (CH 436) from siliconcarbide/ silicon-carbide and viton in a
separate oil chamber. Oil inspection from
outside.
