The BT777 is a compactly designed stationary mounted seal for application in heavy-duty process pumps. Specifically designed for use in poor lubricating media, the BT777 is a high performance seal with the following features
Seal faces designed by FEM for optimum face presentation.
Distributed flush flow providing best possible cooling and de-gassing performance.
Stationary design isolates flexible element from shaft deflection or vibration.
Angled set screw configuration of rotary collar prevents angular misalignment of rotary seat.
Eliminates face "swashing".
Narrow face design reduces interface temperatures and allows seal operation at low margins
over vapour pressure.
Unitised construction eases installation and simplifies conversion from other seal designs.
The BT777 is ideal for a wide variety of process applications, particularly those more difficult duties where safe, secure sealing is the first consideration.
Available in a range of materials and seal configurations, the BT 777 will give long, trouble-free operating life, reducing equipment downtime and maintenance cost.
