8 Cleaning and maintenance
AL HPM
8.1
Cleaning (CIP)
The unit has to be cleaned regularly, depending on the type of operation. Dirt in the pipes and chambers can lead to
contamination and therefore pollution of the product (when next commissioned).
The cleaning (CIP) of the machine is carried out in combination with the cleaning of the tank or when cleaning the pipe system of
the entire installation.
The funnel and the ball valve, which should be cleaned manually, have to be removed and replaced by the blind flange supplied.
This guarantees that no CIP fluid, such as lye or acid can escape if the ball valve is opened accidentally.
8.2
The axial face seal
Details of the maintenance of the axial face seal are included in the attached operating instructions for the multi-stage centrifugal
pump LKH.
8.3
C-Ball Valve
The PTFE housing of the ball valve should be checked regularly. The operator can decide on the checking intervals himself,
because it very much depends on the types of powder used.
8.4
Rotor/Stator
The high-seed rotor, and also the stator, react sensitively to foreign objects. Therefore, objects such as, for example, screws,
stones, welding beads, etc. must be prevented from entering the machine.
In the case of highly adhesive and curing media, the machine should also be flushed immediately at the end of the operation.
Depending on the abrasiveness of the mixed product, the mixing tools are exposed to a certain amount of wear. Since the size
of the shear gap can affect the mixing quality, the tools need to be checked for wear from time to time. The operator can decide
on the checking intervals himself, because it very much depends on the types of powder used.
8.5
Barrier fluid installation
Daily fluid level check.
Occasional check of the leak-tightness of the hoses, particularly in the area of screw connections.
8.6
Drive
Details of the drive are included in the separate operating instructions for the multi-stage centrifugal pump LKH.
NOTE!
Please note that the first step of the pump is modified compared to the standard LKH.
