The 1900 close-coupled, in-line pumps with integrated variable-frequency drives are designed to enhance pump and building efficiency. The single- or three-phase 1900 VFD line greatly increases energy efficiency and building comfort. They are available in five basic models ranging in size from 1½ by 1½ inches to 2 by 2 inches, with a flow range of 10 to 250 gpm, and head capability to 160 feet. Rear, pull-out design allows servicing of the pump without disturbing the piping. The units can be installed anywhere in the piping layout. They are self-supported by system piping, requiring no additional strapping or external support. Each can be mounted horizontally or vertically. The motor’s permanently sealed, grease-lubricated ball bearings make the pumps virtually maintenance-free. All the pumps come standard with ceramic seals to meet a wide range of application requirements. The mechanical seal is a design that combines all components of the rotating element into one assembly, making seal replacement quick and easy. One size seal fits all models.
