WellMate WM-9, 30 Gallon, Fiberglass, Bladder Pressure Tank

Construction and Materials

The WellMate WM-9 is a 30 Gallon fiberglass bladder pressure tank engineered for residential and light commercial well water systems. It is constructed with corrosion-proof composite materials, featuring:

• A blow-molded polyethylene inner liner

• A fiberglass and epoxy resin outer shell for long-lasting durability

• Resistance to rust, dents, and harsh environmental conditions

• Especially well suited for aggressive water chemistry and humid environments

Bladder Technology

The WM-9 utilizes bladder technology to separate water and air. This bladder, also referred to as a diaphragm-style separation design, keeps water and compressed air apart so pressure stays consistent and air does not dissolve into the water.

• Helps the tank maintain efficient use in a well system by reducing air loss

• Changes pump operation only when pressure reaches the switch setting, reducing unnecessary cycling

• Reduces short cycling in the water system

Benefits to Maintain Pressure

Consistent Pressure

• Corrosion-proof construction for extended service life

• Lightweight design; the WM-9 weighs less than half of many traditional steel tanks, making handling easier in most cases

• Helps maintain consistent water pressure during normal use as flow demand changes

Pump Protection

• Reduces pump cycling and wear by helping maintain pressure through small draws before the pump is running again

• Helps prevent short cycling, when a pump starts and stops rapidly, because a correctly sized pressure vessel provides the right volume

• When diagnosing rapid starts and stops, this points to assuming the pressure vessel size or condition is the issue only after other causes are ruled out

• Repeated starts can create inrush current five to seven times higher, increasing wear through motor winding fatigue and bearing wear

• In severe cases, short cycling can cut pump life from about ten years to as little as two years before the pump stops performing reliably

Durability

• Rust-resistant for indoor or outdoor installations

• Durable bladder design for reliable operation
