New Constant Pressure System
PENTEK now offers a new water-pressure management system for residential applications - the PENTEK INTELLIDRIVE Intelligent Variable Frequency Drive. The PENTEK INTELLIDRIVE is engineered to work with the submersible well pump motor to provide constant water pressure, and the system operates at variable speeds, based on water demand. The drive is designed for "plug and play" operation by featuring a four-step start-up process. It features a backlit LCD display that delivers status indications and diagnostic messaging. The drive also provides input and output terminals to provide greater options for customizing applications. Currently available in a NEMA 1 enclosure, the PENTEK
INTELLIDRIVE is compatible with submersible three-wire applications for both one- and three-phase motors, and works with submersible motors from 1/2 HP to 3 HP.
