Maintenance

d) Repair the pump with a Seal Kit.

If the High Pressure Pump electric motor fails to
operate, follow these steps to isolate the problem.
a) Ensure that the system is receiving proper

power from the power source.

b) Press “Start” button to start the system. It will

take approximately 2 seconds before the High
Pressure Pump Motor starts. Do not press any
other switch.

c) Measure the AC voltage between terminals

(AC Systems) or (DC systems) on the main
terminal strip.

d) If the voltage measured matches the system

voltage, then problems may be in the power
cable attached to the motor or the motor
internal wiring or windings.

e) If low or no voltage is present, then check for

proper operation of the High Pressure Pump
Contactor. To deactivate the contactor, press
the “Stop” button. To activate the contactor
again press the “Start” button.

f) If the contactor is mechanically operating, but

no voltage is present at the motor terminals,
then the High Pressure Pump Motor contactor
may be at fault.

g) If the contactor does not operate

mechanically, then measure the DC voltage
between A1 and A2 terminals on the High
Pressure Pump Motor contactor coil. It should
read 12V DC when activated.

h) If the contactor coil is receiving 12V DC but

inoperative then the contactor’s coil may be
bad. Replace the contactor.

i) If 12V DC is not present when the High

Pressure Pump is activated, trace the wires
to the main circuit board and measure the DC
voltage at the terminals. It should read 12V
when activated

j) Confirm the HP PUMP “Stop” button

illuminated on the Touch Screen when the
High Pressure Pump is activated. When this
HP Pump “Stop” button is illuminated the HP
terminals on the Control Printed Circuit Board
should receive 12 VDC. If it is not the case,
replace the main circuit board.

A Pressure Pump requiring maintenance within the
warranty period, and if after examination by Sea
Recovery is found to be non-operational due to a
warranty failure, will be repaired or replaced with
a rebuilt pump at Sea Recovery’s option.

A High Pressure Pump requiring maintenance that
is not within the warranty period, or is damaged
due to non warranty reasons, will be repaired or
replaced with a rebuilt pump depending on the
severity of damage.

For repair or replacement, contact Sea Recovery
for a Material Return Authorization and shipping
instructions.

C) High Pressure Pump (Standard Pump):

HIGH PRESSURE PUMP ABNORMALITIES:
1. High Pressure Pump flow is normal when the

system operating pressure is below 100 PSI,
but the flow drops or becomes erratic and
pulsates as pressure is applied.

a) Worn High Pressure Seals from normal use

require replacement.

b) Worn High Pressure Pump valves, valve seats,

valve springs and or valve seat “O” rings are
broken or worn due to normal use and are
allowing internal by-passing. Repair the pump
with a Valve and Seal Kit.

2. Pump is noisier than usual and pulsations are

observed in hoses and gauges

a) Worn or broken Valve, Valve Spring, or

Valve Seat. Repair the pump with a Valve
and Seal Kit.

b) Pump is cavitating and not receiving sufficient

feed water at it’s inlet due to blockage prior
to the pump’s inlet port. Clear the blockage in
the feed water line.

3. High Pressure Pump Leaks Oil
a) Determine source of leak and replace

appropriate associated seal.

4. High Pressure Pump leaks water between

manifold and Drive End.

a) Worn Inlet Packings due to normal use
b) Worn Inlet Packings due to operation under a

vacuum condition
