Engineered for the Essentials

What causes surge or water hammer in a pumping system? The sudden closure of a valve with the pump running or the loss of power to the pump creates a dramatic change in pressure, which can often have dangerous and catastrophic results. Surge Shield™ can give and accept the pressure energy change to keep your pump’s piping safe and running smoothly. When coupled with Blacoh’s patented SurgeWave™ Transient Pressure Monitoring System, you have the comprehensive answer to show what is happening to your system during a surge event and how to protect it.
