The Classic Series of pump lift stations is designed for applications where gravity drainage is not an option. Standard motors are TEFC, 115/230VAC, 50/60 Hz, single phase. Three phase and hazardous duty motors are also available. Standard models are available with flows to 100 gpm and pressures up to 80 ft TDH.

A typical duplex system for pump-down operation will start one pump at a time with rising level, stop both pumps at the desired low level, then automatically change the starting sequence for the next operating cycle. If the liquid rises above the normal start point due to excess demand or pump malfunction, the idle pump will also start and continue to run until the liquid level reaches the desired low level. Alternating pump operation will then be automatically resumed. An optional high level alarm will sound if the liquid level continues to rise with simultaneous pump operation.

A customized, simplex or duplex system can be designed to meet your specific requirements. Tanks can be constructed of various plastic or metal materials, pumps can be air or electrically operated, and level controls can incorporate various technologies. Explosion-proof systems are available for hazardous locations.
