O-Ring is not properly seated air will enter the
feed line causing the System to loose pressure.
Look for air bubbles moving through the
Sea Strainer and into the Feed Line.
Solution
: Properly seat or replace the
Sea Strainer O-Ring.
b) The Sea Strainer mesh screen element is the first
line of defense to trap large suspended solids
entering the Feed Line. Depending on Feed Water
conditions the screen may plug up rapidly. Marine
growth, plastic bags, jelly fish, and other debris
can easily enter the feed line and plug up the Sea
Strainer mesh screen.
System feed water pressure is low and insufficient
to keep the System in operation because the Sea
Strainer mesh screen is blocking feed water flow.
Solution : Regularly check and clean the
Sea Strainer mesh screen. Keep it clear
and free of debris.
6) BOOSTER PUMP
The Booster Pump is a centrifugal type pump. When
mounted at or below feed water level it is able to
draw feed water and deliver it with pressure into the
prefiltration components and High Pressure Pump. If
mounted above feed water level the Booster Pump may
have trouble priming if air enters the feed line.
Prior to assuming that the Booster Pump’s
Electric Motor has failed, perform a Function Test
as described in Section 6.
Problems and Symptoms appearing and caused by the
Booster Pump:
a)
The Booster Pump leaks feed water between the
pump and motor.
The Booster Pump has a ceramic and carbon seal.
Ceramic and carbon seals will weep if the pump is
not operated for extended periods of time. When
used regularly the seal will give approximately
2000 hours of use. The seal continually wears
during use and must be replaced approximately
every 2000 hours of use. If left unused for
extended periods of time seal replacement may
be required sooner.
Solution : Replace seal.
3) INLET CONNECTOR
AS WELL AS ALL FITTINGS AND CONNECTIONS PRIOR TO
THE INLET OF THE BOOSTER PUMP:
Problems and Symptoms appearing and caused
by any fitting or connection in the Suction portion
of the Feed Line:
a)
One or more fittings or connections in the Suction
portion of the Feed Line is causing air to enter the
Feed Line.
System feed water pressure is low and insufficient
to keep the System in operation. This section of
the Feed Line is under a vacuum condition when
the System is in operation.
Look for air bubbles moving through the Sea
Strainer, or feed line.
Solution : Tighten any loose fitting or connection
at the Inlet of the Booster Pump or prior to it that is
allowing air to enter the feed line.
Replace worn or broken seal or O-ring at the Inlet
of the Booster Pump or prior to it that is allowing
air to enter the feed line.
Check positioning of all valves at or prior to the
Inlet of the Booster Pump that may be allowing air
to enter the feed line.
4) INLINE VACUUM / PRESSURE GAUGES
Problems and Symptoms appearing and caused by the
Inline Vacuum/Pressure Gauges:
a)
A Vacuum/Pressure gauge needle does not move;
or does not register proper vacuum or pressure.
The Vacuum/Pressure Gauges have a very
small orifice at the bottom of the pipe fitting
end. This orifice can become plugged with
debris or corrosion.
Solution : Using a small diameter wire clean the
debris from the orifice.
5) SEA STRAINER
Problems and Symptoms appearing and caused by
the Sea Strainer:
a)
The Sea Strainer O-Ring seal is not properly
seated, is worn, or is not properly compressed
allowing air to enter the Feed Line.
System feed water pressure is low and insufficient
to keep the System in operation. This section of
the Feed Line is under a vacuum condition when
the System is in operation. If the Sea Strainer
