Drawdown in Wet Wells

When using self-cleaning strainers on wet well inlets an additional amount of drawdown can be incurred. While not detrimental in itself, this variation should be considered when designing the wet well and or when placing the various low level switches and indicators.

The following formula and chart may be used as approximate values for this additional drawdown. Other factors, such as elevation and barometric conditions will also effect this value.

How The SCS2 Works

These self-cleaning strainers are perfect for:

Lakes - Ponds - Streams

Debris clogging your pump's intake is eliminated when you install a Sure-Flo SCS2 self-cleaning strainer. Gone are those annoying trips into the water to scrub away leaves, algae, or aquatic plants. Because this screen is always clean, your pump can operate at maximum efficiency. It will provide all the water and pressure it was designed to deliver.

Only 35 PSI is required to operate the strainer.

A small amount of water is returned from the discharge line of the pump to the strainer. Inside, two special nozzles spray against the screen, causing it to revolve. Any debris (i.e. algae, aquatic plants, or leaves) attracted to the screen is blasted off every half revolution. Strainers operate in any position.
