Submersible sewage pumps and submersible sewage pump selection guide
Dec 01, 2016

Building drainage pump submersible sewage pump, submersible type has not stopped up the blowdown pump, horizontal and vertical sewage pumps sewage pumps. Due to the smaller building sites, the displacement is unlikely, drainage pump can give priority to the use of submersible sewage pumps and liquid type has not stopped up the blowdown pump, submersible sewage pump general use in important places; horizontal and vertical sewage pumps sewage pumps required isolation base, since irrigation water, and some sites, so less use in the building.

Flow should be living drainage design of the drain pump flow rate selected; when there is discharge regulation, drainage maximum hourly flow of life can be selected. Fire elevator within the sump pump flow rate is not less than 10L/s. Head according to the lifting height of the drain pump, piping losses determined, add a certain freedom of the head. Free head and 0.02~0.03MPa should be used. Pump suction pipe and outlet pipe velocity should be not less than 0.7m/s, and should not be greater than 2.0M/s.
