Synthesis™ Multi-pump
Synthesis™ Multi-pump Control regulates the pressure of a fluid delivery system using a single drive that orchestrates a series of pumps.
Multi-pump systems can operate up to eight pumps as well as a jockey or priming pump. One pump is a variable-speed master while the remaining auxiliary pumps operate at a fixed speed.
The master pump is controlled by a flux vector AC drive from UNICO’s Series 1000 family. Drives are available from 11/2 to 500 hp and are UL and C-UL listed. Input power can be 230 or 460 VAC single- or three-phase or 575 V AC three-phase.
Auxiliary pumps are controlled using motor starters or soft starters. Starters can be customer-supplied or provided with the packaged system.
Manual bypass control is available with packaged systems.
A variety of options is available for conditioning the incoming line, including AC line reactors, isolation transformers, twelve-pulse transformers, and harmonic filters.
Systems can be packaged in NEMA 1, 4, 3R, or 12 enclosures for indoor or outdoor use. Customization is available for special environmental requirements.
Comprehensive start-up assistance, service, and training are available.
