Pump Gland Seals
Description of Application
Many pumps designed for use on corrosive or toxic liquids are equipped with a pump gland seal connection into which a small flow rate of a harmless liquid is continually forced. The seal liquid is forced past the inboard sealing rings into the impeller chamber. Any leakage past the outboard sealing rings is the harmless seal liquid.
Rotameter Solution
The use of a purge type rotameter is the least expensive and most convenient way to set and monitor the flow of seal liquid into the packing gland seal connection.
Model Selection
When the seal liquid is water, the fittings may be brass, but stainless steel may be preferred by the customer. For pressures above 250 psig use Model FAM3220.
