FloJet Accumulator Tank model # 305730001A (DISCONTINUED)


Update 2/1/19:

We now carry accumulators made by Remco in place of the Flo Jet brand. We feel that these are a better unit because of the bladder stem mount and the threaded connection instead of the quick connects. They install and work the exact same way. To purchase the Remco accumulator tank, Click Here


 Note: Accumulators come with (2)1/2" barbed hose fittings and (2)1/2" threaded hose fittings. If you use 5/8" hose you will need port kit part #20381033 that consists of (2) qc x 5/8 barb. Or you can use the qc x 1/2 mpt ports that come with accumulator and adapt your existing fittings. 


Get the best of both worlds!

High flow when you need it and the ability to restrict the flow for sensitive situations.

We now have accumulators made by FloJet you install them in the outlet hose of any diaphragm pump with a pressure switch. They let you restrict the flow of the pump without damaging the pressure switch or relay by excessive cycling.

How does it work?
When the pump starts, liquid enters the reservoir compressing the bladder until the maximum pressure for the pressure switch is reached then the pump shuts off. When water is demanded, pressure in the air chamber forces liquid into the system. Pump stays off until the minimum pressure is reached on the switch. Then pump turns on, reducing cycling leading to longer switch and pump life.
