3" SQE Grundfos 2-Wire

The Grundfos SQE pump does not require a control box to operate. The Grundfos SQE cannot vary its speed without the use of a CU301 control box. Grundfos SQE pumps are commonly used in the Grundfos SmartFlo System to provide constant pressure. The Grundfos SQE can however be used in conjunction with a CU301 Smartflo Kit and R100 remote control for manual control and adjustment. The CU301 control panel is electronic lockable to keep others from altering your adjustments. A professional model CU300 has no buttons and is controllable only with the R100 remote control.

NOTE; Don't confuse feet with a measurement of depth to water or well depth. Feet of head is a calculation of several inputs (converted to feet) for a total calculation of vertical lift in feet required of the pump at a specific GPM.
Example inputs - [add 138 feet if you wish 60PSI available at the pump outlet or 2.3 feet X the PSI required]
Example inputs - [add pump down level (not depth of well] This is the distance in feet to the surface of the water while pump is pumping]
Example inputs - [add any additional vertical lifting in feet required to get water to its final outlet]
Example inputs - [add frictional losses from pump to final outlet in feet of head by using a pipe friction chart]
After a calculation of total head in feet has been made, simply go to a chart of the GPM required. Start by drawing a line straight up from the GPM required. Next go to the left side of graph, find the total calculation in feet and draw a line horizontally. The pump curve just above the intersection of your lines will be the pump that meets your calculation data.
