ASSEMBLY OF COUPLING
Series MD2-B and MD2-C, All Sizes
DANGER !
Follow these directions exactly to avoid injury to self or damage to the pumping unit. Be care- ful to keep the inner and outer magnets at least
(1)foot apart until step 4. Do not engage the magnets in any other fashion.
CAUTION !
Do not place fingers onto the front of pump mounting flange. Align the canister into bore of the bracket and gently slide it in. When the magnets start to engage, the unit will finish engagement on its own very rapidly unless the M10x120mm capscrew is properly used. Make sure fingers are not on the front of the pump. See Figure Sequence 19.
DANGER!
Be certain that the driving means (motor, turbine, engine, etc.) has been “locked out” or made
1.Inspect the magnets for any steel objects, which may be attached. Remove any foreign material.
MD2-B Couplings:
Mount the outer magnet assembly. Locate the outer magnet assembly per dimension (See Figure 18).
MD2- C Couplings:
Units using a NEMA
Apply Loctite® and tighten the setscrews onto the motor or bearing carrier key and shaft.
2.If the bracket is not fastened to a base, clamp it down. Mount the motor or bearing carrier to the bracket. Reach in and rotate the magnets by hand to make sure there is no interference. If rubbing occurs check the dimension in Figure18 or contact the factory.
3.Check to make sure the pump rotates freely by turning the inner magnet assembly. Inspect the magnet to make sure it has not picked up any foreign particles, which could damage the pump. Make sure the canister
4.Use a fully threaded M10X120mm capscrew (jackscrew) to guide the canister into the bracket. Thread the capscrew all the way into the bracket as shown in Figure Sequence 19. Use an overhead hoist to support the pump if possible while guiding the canister into the bracket opening.
Carefully back out the capscrew while guiding the canister into the bracket. Secure the pump to the bracket with four 12mm capscrews.
5.Be certain that the power supply to the pump is “Locked- out”. Check that pump rotates freely by spinning the motor fan blades or the bearing carrier shaft.
