The Multipur backwash filters are used for filtration
of drinking and industrial water to protect the water
mains and the connected fittings, equipment,
machinery, tanks, boilers and production facilities
from malfunction and corrosion damage caused
by foreign particles.
The filters can also be used for filtration of well,
process, boiler feed, cooling and air conditioning
water.

The filters are unsuitable for oils, greases, sol-
vents, soaps and other lubricating media. Water-
soluble substances also cannot be separated off.

The untreated water flows through a stainless steel
filter element in the Multipur. Foreign particles >
100µm or > 200µm are thus retained. Depending
on their size and weight, these particles either fall
directly into the lower part of the filter housing, or
adhere to the filter element.
During backwashing, the seal at the rinsing water
outlet opens. The suction ring segments of the
backwashing element move from the bottom to
the top and back again over the entire filter surface
and thus clean the filter fabric by suction with clean
water at an extremely high flow rate.
Backwashing is carried out automatically at the
end of the set interval.
The pressure difference between the untreated
water inlet and the treated water outlet of the filter
is measured.
The backwashing process is triggered primarily
by differential pressure.
If heavy soiling of the filter element causes the
pressure difference to exceed the preset value
(approx. 0.8 bar) within the preset backwash in-
terval, the differential pressure generator causes
