MAKEUP WATER VALVE: All-bronze float actuated valve, flange mounted in tank head, permits entry of makeup water, when required, to replace system losses. Complete with strainer on makeup water connection.
PUMPS: Regenerative peripheral turbine vane type, vertically split, with removable covers and channel rings, ball bearings, stainless steel shaft, bronze impeller and mechanical shaft seals.
MOTORS: Drip-proof ball bearing type flexibly-coupled to pumps. Single phase motors 3/4 H.P. and smaller have built-in overload protection. Single phase motors 1 H.P. and larger and all three phase motors are furnished with magnetic starters in NEMA-1 wall-mounting enclosures.
UNITS: Unit is factory assembled on single steel base with pump suction piping complete, including strainer in each pump suction line. Simplex unit has one receiving tank, one makeup valve and one pump and motor. Duplex unit has one receiving tank, one makeup valve and two pumps and motors. Triplex and quadruplex units are also available.
OPERATION: Boiler feed pump(s) is controlled by a boiler water level controller mounted on the boiler. These controllers are usually furnished with integral low water cut-off and alarm switches. Boiler feed water is taken from the receiver, and if condensate has been lost in the system, it is automatically replaced by the makeup valve.

PUMP CAPACITY: Multiply the developed boiler H.P. by .07 to determine the evaporation rate of the boiler (expressed in gallons per minute). Next, multiply this evaporation rate by 3 to determine the capacity of the feed pump (in G.P.M). This factor of 3 allows the pump to cycle at reasonable intervals. If one boiler is being fed, a simplex unit may be used, but a duplex unit (with each pump sized to independently feed the boiler has the advantage of providing an emergency standby pump or alternating the pumps for even wear. If two boilers are being fed, use duplex unit and size one pump for each boiler (specify 4-pole double throw transfer switch to cross pump-boiler assignment) or use triplex unit with each pump sized to feed one of the boilers (specify transfer switch to use one pump for standby service).
PUMP DISCHARGE PRESSURE: Discharge pressures in the Engineering Selection Table are pressures at the pump. To compute, add boiler working pressure plus static head (from pump center line to boiler connection center line) plus discharge line friction loss (including pipe, fittings, valves, etc). Convert all factors to P.S.I. before adding. Static head plus friction loss plus a small residual pressure can be estimated at 5 P.S.I. in most cases.
RECEIVER SIZE: Allow approximately one gallon of receiver, capacity for each H.P. of boiler(s) being served. (Example: If two (2) 250 H.P. boilers are being fed by a duplex unit, receiver should have 500 gallon capacity.)
