March 2011
HYDRAULIC HIGH PRESSURE PUMP UNIT HEU 320-40E IS DESIGNED FOR RELIABLE AND CONTROLLED
EXPANDING OF ROCK-BOLTS.
HEU-PUMP HAS OUTFITTED WITH ELECTRIC LS-FUNCTION ENABLE USE IN ELECTRO-HYDRAULIC PUMP
CONTROLS.
HEU-PUMP IS A COMPACT UNIT ASSEMBLED ON A STEEL CHASSIS BEING COMPRISED OF A PRESSURE
CONVERTER WITH ALL NECESSARY COMPONENTS AND INSTRUMENTATION.
HEU-PUMP CAN BE INSTALLED TO ANY MINING MACHINE AND OPERATED WHETHER FROM A PLATFORM OR
FROM GROUND.
CONNECT AN EXPANDING GUN AND WATER HOSE OF PROPER LENGTH AND PRESSURE CLASS TO HEU-PUMP
ASSURES EFFECTIVE CARRYING OUT OF ANY BOLTING PROJECT.

DYNASET HEU-pump can be positioned deliberately, keeping in view following preconditions:
1.
Easy service access to the unit should be ensured.
2.
Pump should be mounted on sufficiently horizontal surface to enable proper working of leakage detecting
bores, which are found on the bottom surface of a pressure converter. Leakage detecting bores are made to
the zones, which separate oil and water chambers from each other.
If the draining from leakage detectors exceeds rate of 10 drops per minute, pump sealings should be
replaced. The drain fluid can be water, hydraulic oil or their solution.
You can choose deliberately how to make pump’s installation to your carrier: either fixed or as a quick
release unit. In later case HEU-pump is easily detached and re-attached to carrier’s hydraulic system with
quick couplings, when pump can be moved from one carrier to another when necessary.

NOTE !
DRAIN LINE OF THE HEU-PUMP IS PRESSURISED WHEN THE UNIT IS IN OPERATION! THEREFORE IT IS
NECESSARY TO SECURE THE LINE WITH APPROPRIATE FITTING AND HOSE POINTING THE DRAIN BURST
UNDER THE MACHINE OR OTHER SAFE DIRECTION.

SAFETY PRECAUTIONS
The pressure in both hydraulic and pumping fluid circuits is considerably high. There at the technical
condition of your equipment should be under constant scrutiny. Especially couplings, valves and hoses
should be maintained tight and clean as well as kept under constant observation.
Hydraulic leakages must be rectified immediately to avoid injuries caused by pressure and hot oil
blowouts.
Follow all your local safety instructions related to the high pressure hydraulics.
Hydraulic system of a carrier machine should be maintained according to the service program.
In order to exclude possible accidents, it is not allowed to clean or inspect HEU-pump when hydraulic
or/and pumping fluid circuit is pressurized. Prior to any cleaning, inspection and service hydraulic
system of your carrier machine must be stopped and both hydraulic and pumping fluid circuits
dissipated.
Always wear appropriate clothing and safety equipment such as goggles, ear protection and safety
shoes at all times when operating the HEU-unit.
When operating the tool, beware of machinery parts warmed by hot hydraulic oil.
Do not lift the tool by the water hose.
NEVER POINT THE EXPANDING GUN AT BYSTANDERS OR ANY INAPPROPRIATE OBJECT!
EXTERME CLEANLINESS MUST BE MAINTAINED WHEN CARRYING OUT ANY SERVICE DISSASSEMBLING
OR REPAIR OF HRN-TOOL AND HYDRAULIC SYSTEM. THIS IS CRUCIAL TO ENSURE SAFE, RELIABLE
AND LONG-LIFE OPERATION OF YOUR EQUIPMENT.
Operators and maintenance personnel must always comply with local safety regulations and precautions
in order to close out the possibility of damages and accidents.
All installation and service of both hydraulic and electric equipment must be performed by qualified
and experienced personnel only.
PUMPING FLUIDS
Water based fluids and sea water can be pumped without any special arrangements, however the
HRN-tool MUST BE FLUSHED AND CLEANED THOROUGHLY after a working shifts with clean sweet water.
Same rule applies to pumping of gelatin and depositing fluids —after having done your job, flush
HRN-tool 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
HRN-tool’s service life time is considerably shortened.
Furthermore, if pumping solution is aggressive to NBR-rubber, special seals and hoses must be used.
WARRANTY
DYNASET products are warranted against defects in materials and workmanship for a period of 12
(twelve) months from the date of purchase. Exceptions are parts subject to normal wear and tear, such
as seals and other parts that become worn through normal use of the unit.
Warranty covers detective parts solely. Expenditure incidental to shipping and replacement are not
covered by present warranty.
The warranty is void if product has been modified, provided with parts other than original or misused.
