Submersible drainage pumps
for chemically polluted drainage water.
Spherical clearance 10 mm.

CH 407, CH 413
Application

Performances

HOMA CH 407 and CH 413 are submersible drainage pumps. They are
used for pumping drainage water which
is polluted with alkaline or acid chemicals. With the advantage of thick wall
casting and viton seals, they are the
ideal solution to pump mediums with
pH-value between 5-14. They are suitable for laundries, car washes, food
industries and many other applications.
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 and
drainage water, pH-value 5-14.
Max. liquid temperature: 35°C,
short term up to 60°C.
Operation: Intermittent.
