Overview

The Inline 1100 is Franklin’s packaged constant-pressure booster: a variable-speed pump and motor assembly, a drive, a pressure sensor and a small tank, built to hold a set pressure as demand changes. It is the same platform the Inline SpecPAK multi-pump systems are built from.

These are the field-replaceable parts: the drive, the pump-motor assembly, pressure sensors and sensor cable kits, tank kits and the seals and hardware that go with them. Replacing the failed assembly is normally faster and cheaper than replacing the package.

Genuine Franklin Electric equipment, factory-new in original packaging — sold and supported by Watermain Supply, an independent industrial supplier.

Before You OrderRead the model and serial number from the unit before ordering: the drive and the pump-motor assembly differ by build. If the drive has failed, check the supply voltage and the sensor first — a bad sensor reads as a drive fault.
