Modifications List

ALTERNATING FLOAT SWITCH: Replaces the two standard float switches on a duplex unit, to automatically alternate the cycle of operation of the pumps and provide simultaneous operation under peak conditions.

MAKE-UP WATER VALVE: In lieu of float switches where pumps are to be controlled by the boiler water level controller mounted on the boiler. Float (mechanically) operated and solenoid (electrically) operated make-up valves are available.

NON-STANDARD TANK SIZES: Units can be furnished with tank capacities other than those shown in the Engineering Selection Table. Diameters and depths of receivers as well as inlet locations can be modified. Multiple inlets and top-of-tank inlets are available.

NON-STANDARD MOTOR ENCLOSURES: Standard enclosures are drip-proof. Totally enclosed and explosion-proof enclosures are available.

CONTROL PANELS: Control components can be furnished in pre-wired wall-mounting, floor-mounting or unit-mounting panels.

NON-STANDARD MOTOR CONTROLS: Selector switches, pilot lights and transformers for motor starters; water-proof or explosion-proof enclosures for starters; combination starters and disconnect switches; combination starters and circuit breakers.

LARGER UNITS: For ratings in excess of those shown in the Engineering Selection Table, consult the factory or local Federal Pump representative.
