SubDrive Key Features:
• Constant water pressure with a wide range of settings 1.7-5.4 bar
• Smaller pressure tank can be used
• Fits the pump to the application – pump speed is controlled to provide the optimum performance without
overloading the motor
• Flexibility – this unit can be used with standard off-the-shelf pumps
• No in-rush (power-on transient) current
• Low motor start-up current (soft-starting)
• Active Power Factor Correction minimizes input RMS current
Protection Features:
• Dry well conditions – with smart pump monitoring (see Figure 1, pg. 10)
• Bound pump – with auto-reversing torque
• High voltage / lightning surge
• Low line voltage
• Open motor circuit
• Short circuit
The Franklin Electric SubDrive is a dependable residential water system
controller that uses advanced electronics to enhance the performance
of standard submersible pumps. When used with the specified Franklin
Electric motor (see Table 1, pg. 3), the SubDrive eliminates pressure cycling
associated with conventional water well systems and owners of private
water well systems can enjoy “city-like” water pressure. Pump speed and
energy consumption automatically adjust to water demand.
In addition, the reduced tank size (see Table 4, pg. 14) allows installation in
small spaces.
