Tools needed:

Tools provided:

• Lubricant for O-rings and equipment shaft OD.

Tools not provided:

• Wrenches to secure housing nuts or bolts

• Allen wrenches for housing cap screws

• Allen wrenches for seal setting devices and set screws

2.1 Install the seal adapter plate on the vessel ange if required.

2.2 Lightly lubricate the equipment shaft along the entire length the

gasket O-rings will contact the shaft. Use the lubricant provided if it is

compatible with the process uid.

2.3 Secure the vessel ange O-ring in the gasket O-ring groove using

the lubricant provided if it is compatible with the process uid.

2.4 Install the MD-200 Seal onto the equipment shaft with the end

containing the setting devices toward the equipment drive end and

position the seal assembly onto the vessel ange. Use the lifting

eyes supplied to gently lower the canister assembly onto the adapter

vessel ange at this time. Care should be exercised when passing

the seal sleeve incorporating the sleeve packing O-rings over any

keyways or threads that may be present. Any steps or shoulders on

and cutting) of these sleeve packing O-rings during installation.

and any optional bearing lubrication ttings are easily accessible.

holding or restraining clamps and complete adjustments so that

the shaft is in its nal operating position.

secure the canister seal assembly to the vessel ange or adapter

plate. Do not over tighten.
