2.0 GENERAL DESCRIPTION
The CaviBlaster®2070 high-pressure water power unit allows the operator to use the
water flow and pressure to generate cavitation at the end of the proprietary nozzle.
The CaviBlaster®cleans the surface of any underwater structure and crushes concrete
using the energy released by the implosion of the bubbles 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/guns, connecting high-pressure hose
and a diesel-powered, high-pressure pumping unit. The zero-thrust gun/guns uses a
trigger-operated valve to control the water stream on and off. If the valve is closed, the
power unit goes into bypass mode unloading the engine and the pump.
FULL LOAD is defined as the engine at full throttle / full
speed. If partially throttled, the engine will stall, creating
an undesirable running condition for the belt drive system.
The CaviBlaster®2070 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 a belt-
driven booster 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 7,250-psi (500 bar).

Ensure that there is a safe area to work while operating
the CaviBlaster®2070.
Seek immediate medical attention if the operator suffers
an injury as the result of contact with the high-pressure
water stream. Serious personal injury can result from
an untreated water injection wound.
3.2 Personal Protective Equipment
Always wear appropriate Personal Protective Equipment (PPE) when operating
this equipment.
Personnel operating or working in the vicinity of the power unit should wear
appropriate hearing protection when the CaviBlaster®system is in use. If the
diver is not wearing a diving helmet, hearing protection is recommended.
CaviDyneTM suggest wearing vented earplugs, such as “Doc’s Proplugs” or
equivalent, for diver hearing protection.
The operators of the CaviBlaster®system should always wear neoprene or
heavy rubber gloves to provide protection to the hands and, in particular, to the
nails. The gloves will absorb most of the energy produced by bursting cavitation
bubbles and prevent the cavitation bubbles from contacting the operators’ hands.
The gloves will also protect operators’ hands from the initial shockwave when the
zero-thrust gun is activated.
Failure to wear appropriate PPE may result in serious
personal injury.

Page 17/38
Failure to flush and rinse the unit can cause the pump
valve(s) to stick in the open position. This will prevent the
system from producing the correct operating pressure.
The feed water inlet connection is located on the control panel (See Figure
2.3). An air powered self-priming diaphragm water pump is supplied to
provide positive inlet water pressure to the main pressure pump. Two
water supply conditions are acceptable for the CaviBlaster®power unit.
Forced inlet water condition using the diaphragm water pump or an
outside water source capable of supplying at least 30 GPM (114 LPM)
at a maximum pressure of 100-PSI (6.9 BAR).
Gravity feeding water source (See Figure 4.4). Use a hose with a
diameter of at least 1” to connect the water tank to the power unit.
Figure 4.3 –Gravity Feeding Source
To use the feed pump supplied with the system:
Connect the cam-lock socket on the 1”feed hose to the water inlet
connection on the control panel (See Figure 2.3).
Submerse the feed hose into the water source.
Prime the pump by filling the body with water.
It is important to keep the feed hose in the water source when the
engine is running and the clutch is engaged or damage to the pressure
pump will result.
Water level
Pump inlet must be
below the tank bottom

Page 18/38
To use force feed from an alternate source:
When feeding the CaviBlaster®with an alternate water source, the
source must supply water at a volume of greater than 30 gallons (114
liters) per minute at a maximum pressure of 100-psi (6.9 bar).
Connect a 1” cam-lock socket on the water supply hose to the water
inlet connection on the control panel (See Figure 2.2).
Turn on the alternate water source.
Ensure that the feed hose is connected to the inlet
connection and the water supply is on prior to
starting the pressure pump. Failure to supply water
to the pressure pump will cause damage to the pump.
To use gravity feed:
Locate the water supply tank so that the tank outlet is higher than the
water inlet on the control panel (See Figures 2.3 and 4.4).
Connect a minimum 1” hose to the water inlet 1” cam-lock plug.
Connect the other end of the hose to the water supply tank outlet.
Make sure the lowest point in the hose line is the connection with the
power unit.
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 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 required pump flow of 20
GPM (76 LPM). A minimum delivery of 30 GPM (114 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 4.4)
