supply or generator, undersized power lead
wires to the System or motor, loose power wire,
or connection at the motor or within the power
supply line, and “burnt” contacts on the motor
starter relay (contactor).
Solutions :
a) Check wiring size and connections to,
from, and in between the Power Supply
and the electric motor. Correct wire size
or any loose wires.
b) Check the capacitor on the motor, and replace
it if it has shorted out.
c) Measure voltage at the motor during attempt
to start it. If voltage drops more than 10%
locate and correct the reason.
d) Check the motor starter relay (contactor) for
“burnt” contacts.
B. The Three Phase (230/380/460 VAC) Electric
Motor “hums”, pulls starting current (locked rotor)
amperage, does not rotate, and trips the supply
power circuit breaker when attempting to operate
the System.
The Three Phase Electric Motor requires
all three power lines (all three phases) to
be operative else it will “single phase” causing
extensive damage to the motor’s internal windings.
Low voltage will also cause the same symptom.
Low voltage is caused by an undersized power
supply or generator, undersized power lead
wires to the System or motor, loose power wire,
or connection at the motor or within the power
supply line, and “burnt” contacts on the motor
starter relay (contactor).
Solutions :
a) Check wiring size and connections to,
from, and in between the Power Supply
and the electric motor. Correct wire size
or any loose wires.
b) Measure voltage at the motor during attempt
to start it. If voltage drops more than 10%
locate and correct the reason. Cross check
voltage across all 3 power leads.
c) Check the motor starter relay (contactor) for
“burnt” contacts.
C. The Electric Motor makes an unusual “grinding”
sound when operated.
Solutions :
a) Check and replace as necessary the front and
rear bearings.
b) Check to see if the fan is rubbing against the
fan guard.
B) High Pressure Pump (Optional Pump):
This High Pressure Pump is a Quintiplex Radial Axial
Positive Displacement Plunger Pump made of high
grade Duplex material specifically designed for sea
water Reverse Osmosis applications. This Pump is
not commercially available. This pump is specifically
manufactured to Sea Recovery specifications.
WARNING : Two similar Pumps are
commercially available. One has a higher
flow rate and the other has a lower flow
rate. Both of these pumps will cause
damage to the Sea Recovery System
because of excess flow or under flow.
The use of any similar pump, not supplied
by Sea Recovery, will either cause
the Electric Motor to fail, or the R.O.
membrane element to prematurely foul.
USE ONLY SEA RECOVERY SUPPLIED
PARTS AND COMPONENTS FOR THE
SEA RECOVERY SYSTEM.
As with all Positive Displacement pumps it must
receive a specified minimum amount of water
at a positive pressure. A vacuum at the inlet
of the pump will cause cavitation and damage.
This pump does not use oil, it is self lubricated
with the feed water. Internal components are
designed for 8,000 hours of continual service in
sea water. As with any component exposed to sea
water, use is best.
The Pump is manufactured to very tight tolerance
spacing between moving parts. Any debris
entering the Pump will cause extensive and
expensive damage to the internal parts. The Sea
Recovery Prefilter will stop any debris and protect
the High Pressure Pump. Use caution when
changing filter elements and do not allow any
debris from the prefilter element to enter the outlet
port of it’s housing.
The High Pressure Pump is not field repairable. If
the High Pressure Pump fails to properly function
return it to Sea Recovery, or to a Sea Recovery
Authorized Dealer for return to Sea Recovery.
