🚰 Pump System

Pressure Tank

A pressure tank is not a pump but an accumulator in the pump system. It stores water under pressure using a diaphragm or bladder separating water from a pre-charged air cushion, which cushions pressure, reduces pump cycling, and helps maintain steady supply.

⚠️ Note: A pressure tank is an accumulator, not a pump — it stores and cushions pressure but does not move water on its own.

Applications

Paired with booster or well pumps to smooth pressure, reduce rapid pump on/off cycling, and provide a small reserve of pressurized water between pump starts.

FAQ

How does a pressure tank reduce pump cycling?
It stores a volume of pressurized water so small demands are met from the tank rather than starting the pump each time, reducing wear from frequent on/off cycles.
What should the air pre-charge be set to?
Pre-charge is commonly set a couple of psi below the pump's cut-in pressure, but the exact value depends on the system. Confirm the correct setting against the datasheet.
