6.1 MECHANICAL SYSTEM
A. MOTOR/PUMP ASSEMBLY. The unit pump is a multi-component
assembly serving to circulate water through the process system.
The pump will increase the system pressure between 35 - 50 PSI
over the plant water supply pressure. The pump is driven by an
electrical motor.
1. Pump casing. The pump
casing is an exclusive
design. The casing is cast
of iron and flanged to
accept the heater/discharge
and cooling tanks. The
casing is the support
element in the pump/motor
assembly and is secured to
the unit base (figure 6.1A).
2. Pump adapter. The pump
adapter is the mating element
between the pump casing the
electric motor. The adapter is machined to accept the pump
seal flush line. The stationary pump seal member is set in
the seal cavity of the pump adapter (figure 6.1A).
3. Electrical motor. The
electric motor is a dual
voltage, 3 phase, ODP
motor. The motor serves
to turn the pump impeller
creating process flow
(figure 6.1A).
4. Impeller. The impeller is
custom designed for the
unit and creates the higher
flow (gpm) from standard
HP ratings (figure 6.1B).
5. Pump Seal. The pump
seal prevents water
leakage from the pump
adapter. The seal is made
up of three items: The
stationary member (seated
in the seal cavity), the
rotating member (placed
on the motor shaft) and
the tension spring (figure
6.1C shows the stationary
member only).
