Deadhead is a condition that occurs when a diaphragm pump operates with no flow due to a closed or blocked discharge valve. To prevent internal parts from damage, the pump recirculates the same water, causing the temperature to rise and shut off.
These flexible pads are installed between the diaphragm and outer diaphragm plate, providing a secondary wear surface that extends the service of a diaphragm. They also provide corrosion resistance when moving abrasive fluids.
There is usually some pulsation of discharge flow in air-operated diaphragm pumps which can cause excess movement. This can be reduced by using pulsation dampeners that have a membrane with a cushion of compressible gas / air behind it that flexes to absorb the pulse, allowing a laminar flow downstream of the dampener.
