Read the instructions carefully and pay special attention to the warnings! Always check the tank cleaning machine before
operation.
Step 9
Capacity Of Supply Pump
The Alfa Laval GJ 8 can be used with either a centrifugal or positive displacement (constant volume), PD, style pump. In
most cases, if the machine is to be used with a centrifugal pump, it should be configured so that the pump will operate close
to its best efficiency point. The end user must, therefore, take all of the plumbing, elevation, and 8 pressure/flow rate
requirements into account.
If a PD style pump (i.e. piston pump, plunger pump, or mechanical diaphragm pump, etc.) will supply the wash fluid to the
Alfa Laval GJ 8 a different set of rules 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, the Alfa Laval
GJ 8 and the plumbing system.
If a PD pump is
used, the Alfa Laval GJ 8 should be sized to, first, match the flow capability of the pump and, second, not exceed the pump's
maximum operating pressure (taking the pressure rating of the plumbing system into account, also).
WARNING: For high-pressure applications (over 250 psig/17 bar), the pressure of the system must "ramp up" to its
operating pressure. If the system experiences a pressure spike or pressure increases at a rate of more than 250
psig per second, the machine may be damaged and parts will wear out prematurely. Damage resulting from this
phenomenon is not covered by the warranty.
4.3 Recycling Information
• Unpacking
- Packing material consists of wood, plastics, cardboard boxes and in some cases metal straps.
- Wood and cardboard boxes can be reused, recycled or used for energy recovery.
- Plastics should be recycled or burnt at a licensed waste incineration plant.
- Metal straps should be sent for material recycling.
• Maintenance
- All metal parts should be sent for material recycling.
• Scrapping
- At end of use, the equipment must be recycled according to relevant, local regulations. Beside the equipment itself, any
hazardous residues from the process liquid must be considered and dealt with in a proper manner. When in doubt, or in the
absence of local regulations, please contact your local Alfa Laval sales company.
