Solving Water Slam Problems with Valmatic SURGEBUSTER ...

2011-1-6  Waterslam Water slam is a commonly occurring problem in pumping systems. It occurs after pump stoppage when system flow reverses back up the pump before a check valve is fully shut. The closed valve suddenly stops the column of water resulting in a water hammer which can potentially damage the whole pumping system. Valmatic Check []

How To Control Surge PDF

2014-2-8  surge control in pumping systems INTRODUCTION Water pipelines and distribution systems are subjected to surges almost daily, which over time can cause damage to equipment and possible contamination. Surges are caused by sudden changes in fluid velocity and can be as minor as a few psi to five times the static pressure.

ROLE OF NON-RETURN-VALVE IN A PUMPING PLANT: ISH

2012-6-7  A large down surge often damages the system due to cavity formation and column separation when the water hammer pressures go below the vapour pressure of the fluid. A non-return-valve (NRV) restricts flow reversal in the system and ultimately keeps water hammer at a lower magnitude. The closure of NRV under different operating conditions lead ...
