Water Hammer and slamming of check valves Decel control in pump applications is often referred to as Pump Control In a pump system liquid is being pushed uphill The force exerted by gravity on the column of liquid as it goes up hill is called the Head Pressure in the system The pump is sized to provide enough Output Pressure to overcome the Head Pressure and move the fluid up the pipe When the pump is turned off the Output Pressure rapidly drops to zero and the Head Pressure takes over to send the fluid back down the hill A Check Valve is used somewhere in the system to prevent this if necessary by only allowing the liquid to flow in one direction Kinetic energy in that moving fluid is suddenly trapped when the valve slams closed Since fluids can t compress that energy is transformed into a Shock Wave that travels through the piping system looking for an outlet in which to dissipate The sound of that shock wave is referred to as Water Hammer The energy in that shock wave can be extremely damaging to pipes fittings flanges seals and mounting systems SOLUTION By using the Pump Flex Decel feature of the VMX Series the pump output torque is gradually and gently reduced which slowly reduces the pressure in the pipe When the Pump Output Pressure is just slightly lower than the System Head Pressure the flow slowly reverses and closes the Check Valve By this time there is very little energy left in
