HYDRAULIC FLUIDS
PUMPING FLUIDS
Most of liquids, which can be transferred by pumping, can be pumped also with HPW-pump.
Water based fluids and sea water 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 life time 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 can not 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.
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 32
for oil’s operation temperature up to 70 °C;
ISO VG 46
for oil’s operation temperature up to 80 °C;
ISO VG 68
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.
