In sewage grinder pumps, domestic wastewater from one or a few households flows by gravitation to a pumping station equipped with one or two grinder pumps, having a discharge pipe of nominal diame
In past “Pumping Prescriptions” columns this year, I have discussed the procedure of piping size selection when given the process flow requirement and how this affects the pump’s power consumption
Part One of this series (Pumps & Systems, August 2014), discussed the new American National Standards Institute/Hydraulic Institute (ANSI/HI 9.8) design standard requirements.
