Duplex Booster Pump Control Panels

Duplex Booster

Product Description

Duplex Pump Controls Panels are designed to operate and control two booster pump motors on a single system.

 

These panels are widely used in those applications where maintaining a specific system pressure is required.

 

Applied Motor Controls’ standard duplex pump panel is designed to provide both “alternating” and “duplexing” modes.

 

Alternating mode: This function provides for relatively equal wear of the two pump motors, typically of the same HP rating, driven by the controller by reversing the “Lead” and “Lag” roles of the motors on each successive cycle. Automatic alternation is accomplished when one or both motors come to a stop.

​

Duplexing mode: This mode provides stand-by capacity for use of a second pump motor when the system demand exceeds the normal requirements of a single motor, or when one of the motors fails.

 

Applied Motor Controls offers a wide range of UL-listed factory-installed options that can enhance the control and protection of the pumps.
