and one vertical pump and motor
assembly. Duplex units have 2 vertical
pumps. All units are supplied with
a gauge glass on the side of the
receiver.
Motors:
Heavy-duty, ballbearing, close-
coupled pump motors with stainless
steel shaft. 3450 RPM for greater
efficiency and more economical
operation.
Make-up Water Valve:
Mechanical, plug mounted valve with
stainless steel float. Rated up to 45
psi inlet water pressure. (A pressure
reducing valve is required upon
installation.)
Receiver:
Heavy gauge steel construction. All
receivers of 45 gallon size and larger
are supplied in duplex design, with
one pump opening covered when a
simplex design is specified.
Operation:
Boiler feed pump(s) are controlled
by a water level controller mounted
on the boiler. If condensate is
lost or delayed in the system, it
is automatically replaced in the
receiver through the make-up water
valve.
Pump Seal (A):
Features the ultimate in ceramic
technology for exceptionally
long life. Seal is carbon ceramic
with EPDM elastomers. Rated for
temperatures up to 300°F.
Isolation Valve (B):
Optional on 4700 Series Boiler Feed
Units. Allows removal of pump
without draining the tank.
