COMPONENT MAINTENANCE &
REPAIR
1.
Inlet Thru Hull Fitting [1]: Keep the Inlet Thru Hull
Fitting free and clear of debris and marine growth. If
the Inlet Thru Hull Fitting is clogged, this results in a
low feed pressure condition, which causes the System
to shut off.
2.
Inlet Sea Cock Valve [2]: The packings and
connections of the Inlet Sea Cock Valve must be tight
and must properly seal. Clean the valve cavity of
debris or replace the seal and seat, or the entire valve,
as required.
3.
Sea Strainer [3]: Keep the mesh screen free and clear
of debris. The Sea Strainer contains a very fine
monel mesh screen designed to trap marine debris
prior to entering the Booster Pump and Pre-filters. If
the mesh screen becomes clogged, it results in a low-
pressure condition causing system shut off.
Standard Sea Strainer
To clean or replace the standard mesh screen remove
the bowl by turning it counter clockwise. Remove the
Mesh Screen from the bowl. Remove the flat sealing
gasket from the bowl and take care to not damage it.
Wipe the sealing gasket with a damp cloth. Lubricate
it sparingly with Parker "O" ring lubricant. Place the
seal back onto the bowl. Seat the mesh screen back
into the bowl. Screw the lid on clockwise. Hand-
tighten only enough to seal water in and air out.
Commercial Sea Strainer
To clean or replace the mesh screen remove the cap
on the top by turning it counterclockwise by hand or
with a spanner tool. Lift the Mesh Screen from the
bowl. Clean the mesh screen and lower it back into
the bowl. Ensure that the seal on the cap is
undamaged and free from debris. Replace the cap
making sure the seal is seated properly.
4. Booster Pump [5]: Replace the ceramic seal
approximately every 2000 hours, or at the sign of
leakage. (P/N HRO BPSK-5):
DISASSEMBLY: Remove the seven bolts holding
the volute to the motor bracket. To remove the
impeller, hold the motor shaft with a large
screwdriver and remove the impeller by grasping it
with your hand and turning the impeller counter
clockwise. Remove the Seal.
REASSEMBLY: Clean the motor shaft and the
bracket of any corrosion or salt deposits. Place the
ceramic seat into the cavity over the shaft. Make
sure that the polished side is toward the end of the
shaft. Tap into place evenly using a hollow piece of
wood or plastic tool. Lubricate the shaft with light
oil and slip the rotating portion of the seal over the
shaft with the carbon element toward the ceramic.
Slide it onto the shaft as far as possible. Apply blue
Loctite to the motor shaft threads. Hold the Motor
shaft and reinstall the impeller. Tighten the
impeller by turning it clockwise until it is snug.
Reinstall the volute. Tighten the bolts evenly.
Thoroughly prime the pump.
The Electric Motor requires front and rear shaft
bearing lubrication every 6 months. Give three
pumps of high temperature motor bearing lubricant
into each grease jerk. Use a Polyurea Base Grease
such as Chevron SRI (Polyurea Base) or Shell
Dolium R (Polyurea Base). DO NOT USE
LITHIUM OR SILICONE BASE GREASE.
5.
Plankton Filter [6] Element Cleaning:
To clean the element, unscrew the blue bowl
counter clockwise. Remove the Plankton Filter
Element from the bowl. Remove the O-Ring from
