Endura™ MD Control Panel

1 - 4 Pump Control Applications (1VFD/Pump)

The Endura™ MD control panels feature the VFDC-4000 Controller for commercial pressure booster applications using 1-4 VFDs.

The Endura™ MD (Multiple Drives) Control Panel is designed for commercial pressure booster applications using 1-4 variable frequency drives (VFDs). Each panel is equipped with the VFDC-4000 Controller and one VFD for each pump.  

The Endura™ MD Control Panel can be configured for simplex, duplex, triplex and quadplex pump control using a single variable frequency drive per pump.  SJE-Rhombus is a UL certified panel shop that can customize the VFDC-4000 control panel to suit specific requirements.
