1 UNPACKING AND INSPECTION
Open the package and check that the product
conforms to your order. Also, check each of
the following points. For any problem or
inconsistency, contact your distributor at
once.
1. Check that the model number indicated on
the nameplate conforms to the
specifications of your order.
2. Check that all the accessories you ordered
are included.
3. Check that the pump body and parts have
not been accidentally damaged or that any
bolts have not been loosened in transit.
2 OPERATING PRINCIPLE
The centrifugal pump is driven by pair of magnets which are incorporated in the
impeller and motor shaft. The sealless pump structure eliminates shaft seals such as
conventional mechanical seals because the pump chamber is shielded by the casings
and the impeller is operated by the magnets. The combined coupling torque of the drive
magnet and impeller magnet gives sufficient driving power against the motor torque.
