PRIVATE WATER SYSTEMS - Installation - Control Units - Sand removal
If sand is pumped occasionally, and a shallow-well turbine pump is in use,
then a sediment trap may be necessary. Sand will gradually cut away the finely-machined
surfaces of the pumping mechanism until it loses much of its pumping capacity.
This happens to a lesser extent with other types of pumps.
Sediment Traps (2)
The sediment trap is a steel container mounted in the pump
suction line. Water from the water source entering the container at the top
is deflected down by a baffle. Speed of water travel is greatly reduced,
allowing time for sand to settle to the bottom. Water, free of sand, then
moves up the opposite side of the baffle and into the suction side of the pump.
Sediment traps require frequent cleaning.
