Read the instructions carefully and pay special attention to the warnings! Always check the tank cleaning machine before
operation.
Step 6
Entry Openings
The Alfa Laval BladeClean should be placed at the bottom of the tank. Entry openings should be provided to accommodate the
weld adapter attached to the Alfa Laval BladeClean. Depending on the position of the agitator blades, the mounting location of
the Alfa Laval BladeClean should be adjusted.
Note:
When in operation, the plunger of Alfa Laval BladeClean rises above the tank bottom to a height of about
5-7 mm
. This
might interfere with low level scrapers in certain tanks. Consult the nearest Alfa Laval office for more information.
Step 7
Vessel Drainage
It is necessary to clean the floor of a vessel, standing liquid will diminish the effectiveness of the Alfa Laval BladeClean.
Wherever possible, the tank floor should be pitched toward the drain and the drainage opening should be large enough to
eliminate or reduce any liquid buildup or puddling. If gravity alone is insufficient, a scavenger or suction pump should be
connected to the drain to suck out the excess wash fluid. If not drained, the water might accumulate and rise above the Alfa
Laval BladeClean outlet, hampering the Alfa Laval
BladeClean’s performance.
Step 8
Filters and Strainers
All tank cleaning systems should be equipped with a filter or strainer that will trap solids 1/16"(1.6 mm) or larger, as these will
clog the Alfa Laval BladeClean. These large particles will not harm the machine, but they can become caught in one of the
internal passages. This would cause a reduction of its cleaning effectiveness due to a loss of flow. Disassembly of the Alfa
Laval BladeClean then becomes a necessity to remove the blockage. In recirculating (closed-loop) cleaning or any other
application where the cleaning solution may carry abrasive solids in suspension, adequate filtration is a must. These particles
can be extremely destructive to the Alfa Laval BladeClean, pumps, valves, and other system components. Filters, properly
installed and maintained, will more than pay for themselves with lower overall operating costs in these applications.
Furthermore, to ensure that clogged filters or strainers are cleaned, we recommend using automatic self-cleaning models.
Step 9
Capacity of Supply Pump
The Alfa Laval BladeClean can be used with either a centrifugal or positive displacement (constant volume), PD, style pump.
The Alfa Laval BladeClean is tested for performance upto 150 Psi (10.3 Bar) and it can be operated at higher pressures as well
depending upon sufficient drainage so as to avoid puddling. If the Alfa Laval BladeClean is to be used with a centrifugal pump,
the end user must take all of the plumbing, elevation, and Alfa Laval BladeClean pressure/flow rate requirements into account.
If PD style pumps (i.e. piston pump, plunger pump, or mechanical diaphragm pump, etc.) will supply the wash fluid to the Alfa
Laval BladeClean, a different set of rules will apply. PD pumps are fixed volume pumps whose flow rate is dependent upon the
speed of the pump; the pumps also have a pressure rating which is the maximum operating pressure.
Note:
Do not confuse the maximum operating pressure of a PD pump with the actual operating pressure. The actual operating
pressure is dictated by the fixed flow rate of the pump and the plumbing system.
