Low Head, Low Flow Diaphragm Pumps – A diaphragm pump is a positive displacement pump appropriate for moving small amounts of water at low heads. It will pump at least some water even in low light conditions. SunPumps here in Arizona makes a bronze and stainless steel pump series with flow rates up to 14 litres per minute and depths of 70 meters. Shurflo also makes a diaphragm pump with a plastic case that can pump up to 7 litres per minute at 70 meters.

Medium Head, Medium Flow Helical Rotor Pumps – The Grundfos SQFlex is a fantastic pump with an integrated electrical drive that allows the use of AC or DC power from 30 volts to 300 volts. This is a positive displacement pump that works on the principle of Archimedes screw and can pump water at very low light levels. The same 1hp motor and drive are used in all SQFlex models with different pump ends to match the head and flow requirements. This is by far our fastest selling pump.
