FLO-FAB S-FOM, D-FOM or Q-FOM Pumping Sets offer several advantages over jobsite assembly of components. Most important is the sole responsibility of the manufacturer for providing predetermined results. One organization selects and coordinates components, fabricates the steel baseplate, the pipe fittings and installs the electrical control panel.

Duplex models are normally-stocked to cover most applications. Other models can be manufactured to meet the requirements for a specific application. A shop drawing and a wiring diagram, both incorporating a list of components, are prepared for approval prior to fabrication. The electrical control system includes one magnetic starter for each pump, indicating lights, a control transformer and a system control pressure switch (see EP panel for complete details). When pump operation is intermittent a control is frequently used to alternate the pumps (on duplex units only) and automatically turn on the back-up pump in case of malfunction. Models CYS are industrial pumps. These pumps have become the industry standard in fuel oil transfer units. 

Models CYS pumps feature a new open-core design that provides improved performance at higher speeds and pressures. The rotor heads are hydraulically-balanced to provide minimum end clearance, assuring instant priming and instant capacity over a wide viscosity and pressure range. The pump is provided with a new improved mechanical face-type seal and Teflon impregnated outboard designed for direct drive. They are capable of handling inlet pressures as high as 200 PSI at standard 1750 RPM motor speeds. As shown in the tables herein, pumps are provided in five sizes. Each pump is provided with an internal relief valve. FLO FAB duplex fuel oil transfer units are ideal in fuel oil transfer systems and generators.
