2 MD-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 seal 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 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 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 packing O-rings during installation.
2.5 Position the canister seal assembly so that the barrier gas ports
and any optional bearing lubrication fittings are easily accessible.
2.6 Reinstall the shaft coupling and/or drive. Remove any shaft
holding or restraining clamps and complete adjustments so that
the shaft is in its final operating position.
2.7 Install and tighten the vessel flange studs or cap screws to
secure the canister seal assembly to the vessel flange or adapter
plate. Do not over tighten.
2.8 Tighten the set screws in the sleeve drive collar uniformly with an
Allen wrench.
2.9 Remove the setting devices. Save the setting devices and
attachment hardware for future use.
