ASME Bladder Type Hydro-Pneumatic Tanks
In contrast from diaphragm tanks, bladder tanks completely enclose the water inside a replaceable butyl rubber bladder (other bladder materials available upon request), eliminating problems such as water-logging and tank corrosion. Air precharge pressure is maintained using a car-tire type valve, also known as a Schrader valve.
Hydro-pneumatic tanks help protect the pump and pressure switches in a system against short-cycling. The tanks are designed to deliver water under pressure between pump cycles to meet demand, also known as the required tank drawdown. Hydro-pneuamtic tanks improve the system operation and extend the pump motor service life by reducing surge pressures, dampening pressure spikes, and minimizing pump run times.
Similar to other items in a heating or cooling system, bladder tanks must be maintained to ensure proper operation. Precharge pressure must be field adjusted per the operating conditions of the system it is being installed in. See IOM for more details regarding proper maintenance procedures.
