Deadheading pump
WebMay 13, 2012 · Put on a relief valve set a couple of percent higher than dead head pressure, or equal, or 1/2 percent lower. Recirculate the relief discharge back to the tank. Put the flow switch on the relief line. Now. Sounds like somebody picked a bad pump for your application, or is running it at a bad flowrate. WebDeadhead Capability: The EVO Series™ Electric Diaphragm Pump provides real deadhead protection.A built-in encoder can sense the pumping speed, slow the motor down and hold system pressure for long periods of time. Its automated system allows the pump to restart the process without priming and can be programmed for automatic shutdown.

WebNo pump is perfect with 100% efficiency. Energy lost in friction and hydraulic losses transforms to heat - heating up the fluid transported through the pump. The temperature rise can be calculated as dt = Ps (1 - μ) / (cp q ρ) (1) where dt = temperature rise in the pump (oC) q = volume flow through pump (m3/s) Ps = brake power (kW)
