CENTRIFUGAL CONDENSATION RETURN UNITS
Bulletin 109C
RECEIVER:
Low inlet type receivers are of heavy, close grained cast
iron construction. No foundation bolts are required. May be installed in shallow
pits or on floor level.
MOTORS:
Single phase, 3450 RPM, 115/230v. capacitor type
motors have built-in overload protection. Three phase, 208/230/40v. motors are
furnished with magnetic starters (mounted and wired on unit), with overload
relays for motor protection.
FLOAT SWITCH:
Enclosed, automatic float switches with adjustable
float travel and seamless copper float furnished for each motor.
PUMP:
Bronze fitted centrifugal pump design assures long operating
life without parts replacement or loss of pumping efficiency, by eliminating
close clearance moving parts. Stainless steel shafts, bronze guide bearing
protected by mechanical shaft seal, and single piece construction insures
vibrationless operation.
Single Unit consists of one receiver, one
pump and motor unit and one float switch (plus one magnetic started for three
phase units).
Duplex Unit consists of one receiver, two pump and motor
units and two float switches (plus two magnetic starters for three phase units).
An automatic alternating float switch can be furnished on Duplex Units in place
of the two standard float switches.
