2.0 GENERAL DESCRIPTION
The CaviBlaster 2828-E60 high-pressure water power unit is designed to use water flow
and pressure to generate cavitation at the end of the proprietary nozzle.
The CaviBlaster cleans the surface of any underwater structure using the energy
released by the implosion of the bubbles created during the cavitation process. When
directed at the surface being cleaned, the energy released by the collapsing bubbles
causes marine growth to be removed from the surface.
The system consists of a portable, zero-thrust gun, connecting high-pressure hose and
an electric motor-powered, high-pressure pumping unit. The zero-thrust gun uses a
trigger-operated valve to control the water stream off and on. If the valve is closed, the
power unit goes into bypass mode unloading the engine and the pump.
The CaviBlaster 2828-E60 power unit is a complete “plug and play” system built into a
self-supporting frame that allows quick deployment and/or installation of the unit. Water
can be supplied from either a pressurized source, directly from the natural source via an
electric feed pump supplied with the power unit, or from a gravity feed storage tank.
The unit is equipped with many features to maintain operator safety while operating at
pressures of 2,800 psi 190BAR) with safety overload protection rating to 3,080 psi
209BAR).

long service life.
An electric boost pump is installed to provide positive inlet water pressure to the main
pressure pump. The power unit incorporates a high-flow centrifugal feed pump to
support the main pump system. The feed pump is capable of providing 50 to 70 GPM of
water for the system.
Page 14/35
For more information please email [email protected] or call 1- 352)275-5319
Pump oil may have been removed for shipment.
Check oil level prior to starting.

4.3.2 Priming the System Using the Feed Pump System
Attention to priming the system is necessary. The feed water suction hose inlet
connection is located on the water connection panel See Figure 2.2). The clear)
suction hose should be straight and at a slight downward angle from the inlet
connection on the water connection panel, with no “humps” in the hose so that trapping
of air pockets and creating an air lock is minimized. During the priming cycle the suction
hose should always remain below the height of the inlet connection unless connecting
with a positive pressure water source.
Note: Assure that no air is trapped in the feed hose to cause an air lock leading to the
feed pump.
The feed pump system is fully capable of self-priming. The feed pump should be
charged with water to more effectively draw from the source. It is suggested a positive
pressure water source be utilized to initially charge the feed pump system.
Note: The feed pump may require upwards of 5 to 7 minutes to draw sufficient water to
prime the system before starting the main pump system.
Once fully primed should a restart be needed, confirm priming is complete, without
trapped air pockets.
4.3.3 Three water supply conditions are acceptable or the CaviBlaster
power unit.
a) Forced inlet water condition using the supplied electric water pump.
b) An outside water source capable of supplying a minimum of 40 GPM 150
LPM) at a maximum pressure o 50-PSI (3.5 BAR).
c) Gravity feeding water source See Figure 4.3). Use a hose with a diameter of
at least 1-1/2” to connect the water tank to the power unit water inlet.

b) Using Force Feed Supply rom an alternate source:
Verify the main power switch, HPP motor switch and feed pump motor are
switched to OFF.
Ensure the E-Stop button is ‘Pushed In’ so that the power supply has been
disconnected. See Figure 2.2).
When feeding the CaviBlaster with an alternate water source, the source must
be capable to supply water at a volume of greater than 28 gallons per minute
106 LPM) at a maximum pressure of 50-psi.
Connect a 1-1/2” cam-lock socket on the water supply hose to the water inlet
connection on the control panel See Figure 2.2). Confirm system is primed.
c) To Use Gravity Feed:
Locate the water supply tank so that the outlet of the supply tank is higher
than the water inlet on the control panel See Figures 2.2 and 4.3).
Verify the main power switch, HPP motor switch and feed pump motor are
switched to OFF.
Ensure the E-Stop button is ‘Pushed In’ so that the power supply has been
disconnected. See Figure 2.2).
Connect a hose minimum 1-1/2” diameter) to the water inlet 1-1/2” cam-lock
plug). Connect the other end of the hose to the water supply tank outlet.
Open any valves installed in the water supply line.
Make sure the lowest point in the hose line is the connection with the power
unit.
THE PUMP SYSTEM MUST BE FULLY PRIMED BEFORE STARTING THE
HPP PUMP OR SERIOUS DAMAGE TO HPP PUMP WILL OCCUR. REFER
TO SECTION 4.3.2 ABOVE FOR PRIMING INSTRUCTIONS.
It is essential that adequate water is supplied to the water supply tank to
maintain the water level several inches above the tank outlet. Failure to
maintain an adequate water level in the supply tank during operation could
starve the pressure pump of water causing damage to the seals or other
components of the pressure pump.
Ensure that the water source can reliably deliver the maximum pump flow of 30
GPM 115 LPM). A minimum flow of 40 GPM 150 LPM) is recommended to
ensure that the pump is not starved of water. If connecting to a gravity feed tank,
locate the tank outlet above the water inlet connection on the power unit to
ensure a flooded suction line. See Figure 4.3).
