7.2 Inlet filter
TM075393
Inlet filter accessory
When using SCALA products for pumping rainwater or
well water
, we recommend installing a filter on the inlet
side to provide clean water to increase the longevity of the
pump, and to protect it from sand, gravel or other debris.
Features of the filter include:
• Clean water provides long life for the pump.
• Quick and easy installation.
• Easy maintenance and cleaning.
The square mesh allows a uniform flow along the entire
surface of the cartridge itself, which minimizes the
possibility of clogging. Also, the smooth surface of the
filter ensures easy washing and cleaning. The filter
cartridges provide a nominal filtration with an efficiency of
80 %. If properly used, they can be used repeatedly
maintaining constant efficiency.
The inside core is manufactured from talc-filled
polypropylene and a welded nylon net. The filter housing
is composite.
