3" SQE Grundfos 2-Wire

(Replacement variable speed pump required for SmartFlo Systems)

Deep Well Submersible Pumps


Great on generators !

Note; The Grundfos SQE pump is a primarily a replacement pump used in the Grundfos Smartflo System. To accomplish constant pressure with the Grundfos SQE pump, a Grundfos CU301 Smartflo Kit (CU301 control box and transducer) along with a 2 gallon surge tank must be added. (see complete kits available by Clicking Here). It might also be used to perform the same as an Grundfos SQ model when recommended voltage is applied to the 2 line leads. The Grundfos SQE pumps are also a good choice for replacement of your current pump that uses a pressure tank and switch system. When the tank actually does fail, adding a Grundfos CU301 Smartflo constant pressure kit and 2 gallon tank will eliminate the need to replace the failed pressure tank.

Independent testing showed that a Grundfos SQE pump only will function on a deep cycle 12 volt battery and modified sine wave inverter which meets Grundfos approved ratings of 110% of P1 applicable to each model. Testing also showed that a true sine wave inverter which meets Grundfos approved ratings of 110% of P1 applicable to each model should be used for the complete Grundfos Smartflo System.

NOTE: The MSE3 motors for SQE pumps are built to withstand up to a 4000V transient spike (IEC 60664-1, Overvoltage category III). However, lightning can generate voltages that exceed this level, and additional transient protection devices are recommended to protect the submersible motor in areas with a high degree of lightning activity. The following transient protection device has been tested successfully together with SQE pumps, and can therefore be recommended: Delta Lightning Arrestors - Type LA 602

Available from:
Delta Lightning Arresters, P.O. Box 750, Big Springs, TX 79721
Telephone: (915) 267-1000, fax: (915) 267-1035

Provides protection against transients as indirect lightning and surges (IEC 61643-1 Arrester class II, 8s/20s pulse, 15 kA peak current).


Grundfos SQE 2-wire assembly's include pump and motor
[ 2-wire describes (2) control wires from pump + (1) green - ground wire from pump ]

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.
