2 MW-200 Seal Installation
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 setting devices and set screws
2.1 Install the seal adapter plate on the vessel flange 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 fluid.
2.3 Secure the vessel flange O-ring in the gasket O-ring groove using
the lubricant provided if it is compatible with the process fluid.
2.4 Install the MW-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 flange. Use the lifting
eyes supplied to gently lower the canister assembly onto the
adapter plate. Do not bolt the canister seal assembly to the adapter
plate or vessel flange 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 the equipment shaft should be beveled to prevent
damage (pinching and cutting) of these sleeve gasket O-rings
during installation.
2.5 Position the canister seal assembly so that the liquid barrier ports
and any optional bearing lubrication fittings are easily accessible.
