Davies Pumps Flexpansion water pressure tanks are suited for all water systems including industrial, domestic and agriculture. The tanks are constructed with a polypropylene liner combined with high-grade butyl diaphragm to isolate water and air, preventing the growth of bacteria in the tank. The cast stainless steel water connection is used for corrosion resistance.

The use of a Flexpansion pressure tank in a pressure system can increase efficiency and pump life by reducing cycle time and also prevent shocks on the system from water hammer or thermal expansion.
