HIGH PRESSURE DUST SUPPRESSION SYSTEMS
OPERATING INSTRUCTIONS
Dynaset HPW Dust high pressure suppression system is based on HPW-pump and is specially designed to
prevent dust emissions at crushing, pulverizing, demolition or to any process of dusting materials. HPW dust high
pressure suppression system can be used effectively applications like quarries, recycling and waste management,
material handling etc.
Dynaset wide HPW pump series produce needed water pressure and flow to different dust suppression application.
High pressure water mist is spayed via dust suppression nozzles round the dust particles. The weight of the water
bounded dust particles increases multiply that makes them fall down. Low water consumption is achieved by tiny
water mist that do not irrigate machine and surroundings wet. Various applicable forms of high power jets are
available, turbo jets or dousing umbrella for area suppression, falling debris etc.

GENERAL
HWP High Pressure Dust Suppression system forms microscopic water
mist which means low water consumption and low costs. Mist-like
atomized water binds even the smallest dust particles and makes them
heavier to falling down in a controlled manner. Dust suppression system
avoid soiling of surroundings, inhibits mud sagging keeping the working
area almost dry.
The compact hydraulic operated high pressure pump is easily mounted
onto the machine.
HPW pump is controlled by electric ON/OFF valve on machinery cabin.
Hydraulic valve kit controls the water pressure with pressure reducer
and the oil flow limiter. Pressure reducer and solenoid valve to
appropriate application control nozzles water flow. Pressure compensated
oil flow-limiter controls the biggest running speed of the HPW-pump.
Excavator fitted Dynaset HPW-Dust suppression system are dual power
stage type. Continuous basic dust suppression is supplement with a
high power mode, which is used as frequently as necessary to suppress
dust created during demolition by fallen debris by bulk-loaded dump on
a truck’s platform etc.
Technically dual stage power output is implemented in two different
ways:
1. In a Dual Water Circuit (DWC), both basic and high power
levels use individual high-pressure nozzle pairs. The high power
dust suppression is switched on by activating separate water
solenoid valve.
High power suppression nozzles can be the first time coarsely
pre-aimed to an assumed dust source according to task demand
and conditions. Exact aiming is done after the experiment.
2. In a Single Water Circuit (SWC), the same nozzle pair is for
both basic and high power dust suppression, using two separate
hydraulic flows – one for each power level of dust suppression.
Prior to switching on the dust suppression, operator have to aim the
attachment with dust suppression nozzles to a dust source.
Front loader’s bucket or mobile crusher’s feed hopper and conveyors
can be equipped with dust suppression-nozzle pipe(s) of a single
water circuit mode continuous mode, dust suppression system

HPW-pump is to be connected to hydraulic system of carrier machine, as well as to pumping fluid circuit.
HPW can be installed with no particular efforts to system based on either constant or variable displacement
hydraulic pump, as well as to closed hydraulic systems.
ATTENTION !
Check the ports of your HPW-pump and connect it to hydraulic and pumping fluid circuits according to their
markings !
If the hydraulic pressure line will be connected by accident to the return port and return line correspondingly to
the pressure port, it will not cause any harm to HPW-pump, however pump will not operate.
In order to reduce both pressure pulsation and return line oscillation, the flexible hose with textile fabric cord is
recommended to be used in return line to protect from damage low pressure units, such as oil cooler.
Prior to connecting HPW-pump to hydraulic circuit, compatibility of used equipment should be ensured.
Hydraulic pressure and flow rate produced by hydraulic circuit should meet values demanded by your HPW-pump.
Refer to the technical specifications.

HYDRAULIC FLUIDS
Wide range of standard hydraulic fluids can be used with the DYNASET hydraulic equipment.
Subject to the operating temperature, following mineral hydraulic oils are recommended:
ISO VG 32S for oil’s operation temperature up to 70 °C;
ISO VG 46S for oil’s operation temperature up to 80 °C;
ISO VG 68S for oil’s operation temperature up to 90 °C.
Synthetic and bio-oils can be used as well if their viscosity characteristics and lubricating efficiency are
corresponding to above mineral oils. Automatic transmission fluids and even engine oils can be used, provided
that they are allowed to be used in hydraulic system of your carrier machine.
Prior to use special hydraulic fluids a with DYNASET equipment, please be kindly requested to contact nearest
DYNASET representative for an advice.
Having started a machinery and job - for instance, demolition of the building - an operator stars the basic dust
suppression by activating a hydraulic solenoid valve.
Basic dust suppression nozzles catch the dust straight at its source. High power dust suppression can be used
to kill the dusting of bigger objects - a debris pile, fallen fragment, etc.
An attachment with nozzles should be aimed to the dust-emitting object by activating either the water or hydraulic
solenoid valve - depends on system’s structure, see pages 9-10).
The high power dust suppression is intended for discontinuous use, but if the water pipeline is available, the high
power mode can be used on continuous basis when necessary.
OPERATION
PUMPING FLUIDS
High-pressure dust suppression nozzles and HPW-pump required at least mesh 80 (177 μm) water intake strainer.
Observe strainer condition regularly.
If any nozzle’s spray form going to be varying or to be clogged, the nozzle should detach and flushed with clean
water against the working flow direction. Flush suction strainer with water or change it to the new one.
Water based fluids and seawater can be pumped without any special arrangements, however the pump MUST
BE FLUSHED AND CLEANED THOROUGHLY after a working shift with clean sweet water. Same rule applies to
pumping of gelatin and depositing fluids. After having done your job, flush HPW-pump with clean water or suitable
solvent.
Solvents, fuels and oils can be pumped without any special arrangements.
Fluids with abrasives or high content of solids can be pumped as well, but should be kept in mind, that HPW-pump’s
service lifetime is considerably shortened. Pls. note that DYNASET HDF-pump series is especially designed for
pumping of abrasive fluids.
When HPW-pump is going to be used as a self-priming unit with a special or high viscosity liquid, the flow and
self-priming conditions should be evaluated. If the self-priming property cannot be reached, pumping liquid is to
be fed with certain pressure (refer to the TECHNICAL SPECIFICATIONS), or the pump should be used at lower
hydraulic flow.
Furthermore, if pumping solution is aggressive to NBR-rubber, special seals must be used.
HPW-models made of special materials or with coated parts are available by request.
ATTENTION: Preventing freezing nozzles, water circuit and pipeline at HPW dust high pressure suppression
system, draining and air flushing have to perform before ambient temperature reaches 0°C (32°F) or lower.

issued by local authorities.
1. Precondition:
• Product is permanently useless or beyond repair.
• Before transportation get off all used agent (oil, cooling liquid) and dirty filters.
Items requiring special handling can normally be done by authorized waste management facility,
if not:
• Separating the base materials, iron, copper, steel, electronics, removing paint, polyester resin,
and insulation tape and/or plastics residues from all components.
• This ‘waste material’ can now be recycled.
2. Deliver the recycling and waste material to waste management facility.
Note! Customer can send the DYNASET equipment for reuse or recycling to the Dynaset Oy or to
other location determinate by Dynaset representative.
• Customer pays shipping cost.
• Equipment must be adequately packed for shipment.
• Shipment documents must contain purchaser’s name, contact information, equipment type and
serial number.
MAINTENANCE
If any nozzle’s spray form going to be varying or nozzle clogged, the nozzle should detach and flush with clean
water against the working flow direction. Flush suction strainer with water or change it to the new one.
Due to small number of moving parts, in normal operating conditions HPW-pump does not require any other
service, except replacement of sealings or occasionally of water valves, which depends on content of abrasives
in pumping fluid, as well as on cleanliness of hydraulic oil.
Check constantly whether the fluid dropping from pump’s leakage detectors is growing and replace sealing in
proper time to exclude intermixing of hydraulic oil and pumping fluid. To enable the easy surveillance, pump
should be kept clean.
Observe also couplings, valves and hoses that they are tight with no bleeding. Clean pump fluid filter and
suction strainer guarantee long components life cycle.
Prior to any cleaning, inspection and service hydraulic system of your carrier machine must be stopped and all
hydraulic fluid circuits depressurized.
WHEN CARRYING OUT ANY DISASSEMBLING OR REPAIR OF HPW-PUMP, ABSOLUTE CLEANLINESS
MUST BE MAINTANED TO ENSURE RELIABLE AND TROUBLE-FREE OPERATION OF YOUR EQUIPMENT.
