Davey Supercell Pressure Tanks

Description

Davey Supercell Pressure Tanks are designed to improve pump performance, reduce pump cycling, and extend the life of pressure systems. They are commonly used with home pressure pumps, variable speed systems, and pressure boosting installations where smooth operation and system protection are important.

The heavy duty butyl diaphragm is safe, non toxic, and approved for potable water use. It meets major international standards for drinking water applications.

Supercell pressure tanks help maintain steady system pressure, reduce pump starts, and absorb pressure fluctuations. This reduces wear on pumps, motors, and controllers. Larger tanks also provide increased draw off volume before pump starts. This is generally 20-30% of the full tank volume.

Why we like them

You do not always need a pressure tank, but in most fixed speed pump systems they are a great addition. They help reduce water hammer, cut down on pump cycling, and can lower power use by up to 30 percent when sized correctly.

We do not recommend them on variable speed pumps, as these already have a pressure tank built in and do the job themselves.

Mounting Types

Pipe mounted can be mounted on pump headworks or on top of Davey Pressure controller.

Free Standing can be mounted next to the pump on the included foot. We recommend a flexible reinforced hose for this install.

Warranty Period

This product is backed by a warranty period of 5 years. Contact us if you need help confirming coverage or making a claim.

How it works

Inside the tank a butyl diaphragm separates the water from a cushion of air. When the pump runs it pushes water in and compresses that air. When you open a tap, the stored water comes back out before the pump has to start. Usable draw off is generally 20 to 30 percent of the full tank volume, so a 60 litre tank gives you roughly 12 to 18 litres between pump starts.

Where it fits

Home pressure pumps, pressure boosting installs, and any fixed speed system where the pump is cycling more than it should. The tank also absorbs pressure fluctuations, which is easier on the pump, the motor, and the controller. On a variable speed pump, leave it out.

Mounting types

Pipe mounted tanks fit on the pump headworks or on top of a Davey pressure controller. Free standing tanks sit beside the pump on the foot supplied. For a free standing install we recommend connecting with a flexible reinforced hose rather than rigid pipe, so vibration and movement do not load up the fitting.

Sizing notes

Bigger tank, more water drawn off before the pump starts, and fewer starts over the life of the system. The 8 and 18 litre pipe mounted tanks suit a tidy install on the pump itself where space is tight. The 60 and 100 litre free standing tanks are for where you want to genuinely cut cycling on a busy household. Note that a Grundfos CU 302 needs a tank of 18 litres or larger to work correctly.
