“The LIQUIDYNE seal is robust and can stand a good deal.
The big advantage is that the extent to which a seal is worn down is
measurable. This enables us to plan maintenance and run our plant
to a controlled stop rather than have an emergency shut down.”

Secure pump performance
Check sealing conditions at any time and effectively predict remaining seal life
with the water-lubricated LIQUIDYNE seal. Its unique Condition Monitoring
function helps to optimize the pumping process, prevent unnecessary
maintenance and eliminate sudden pump failure. Optimize the Mean Time
Between Maintenance (MTBM) to minimize the total cost of ownership.

Extending pump life
The water lubricated LIQUIDYNE lip seals
run over a partially grooved bush placed
over the pump shaft. The helical grooves
and the peripheral velocity of the bush
create water flow between the grooves
and the lip seal. This process creates a
hydrodynamic lubricating film, reduces
water pressure to atmospheric level and
cools the heavy loaded part of the bush.
Over time, the helical grooves on the
bush gradually wear down. Less water is
transported over the bush and the amount
of water leaving the discharge decreases.
When the discharge flow is at 20% of the
initial flow, maintenance is required.
By plotting this decrease in discharge flow,
you can plan maintenance more efficiently,
optimize MTBM, reduce costs and prevent
sudden pump failure.

Innovative details
The LIQUIDYNE was initially developed
for heavy duty dredging pumps. It’s the
LIQUIDYNE’s innovative details that enable
these pumps to deliver a top performance.
Carefully selected materials, unique geometry,
compound and coating of lip seals and
grooved bush and the unique water lubricated
feature are just a hand full of details that
enable the LIQUIDYNE to outperform
other technologies.

‘Shell Global Solutions has listed the LIQUIDYNE pump shaft seal as best
practice for use with its cooling water pumps worldwide.
The possibility of continuously monitoring the actual state of the
LIQUIDYNE seals enables Shell to plan maintenance of its cooling water
pumps. As a result, the stability and reliability of the pumping operation
are increased considerably and maintenance costs are reduced.’
