The heart of the "1600" Series pump is the replaceable permanently lubricated bearing cartridge. The exclusive "1600" cool bearing cartridge design isolates the bearing from the effects of system temperatures to greatly extend bearing life. In addition, standardization of the bearing cartridge means that a single bearing cartridge can be used to service the entire product line.
The following charts illustrate the performance of the "1600" Series pump product line.
