The two illustrations on the left are for exactly the same application; the first shows a typical installation with a free discharge. The second takes advantage of siphonic recovery, and in so doing, offers a significant reduction in pump head and power.

The concept of siphonic assistance has been around for centuries, but is often overlooked for pumping applications. By submerging the outlet of the discharge pipe, the pump static head is reduced simply to the difference between the sump water level and the discharge surface water level.

Traditionally, this method has been widely used in the Land Drainage industry, but can equally be used in many other applications. All that is required is a slight modification to the pipework design and the installation of a siphon breaker valve. The benefits are recouped whenever the plant is running.
