Product Description
Duplex Pump Controls Panels are de-signed to operate and control two booster pump motors on single system.
These panels are widely used in those ap-plications 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 pro-vides for relatively equal wear of the two pump motors, typically of the same HP rating, driven by the controller by revers-ing the “Lead” and “Lag” roles of the mo-tors 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 sin-gle motor, or when one of the motors fail.
Applied Motor Controls offers a wide range of UL Listed factory-installed options which can enhance the control and protec-tion of the pumps.
