Project Description
- Accommodates shaft deflections due to
stationary design - Can be designed for individual pump
application with corresponding connection
parts to be adopted to the pump seal
chamber - Optimum heat dissipation due to integrated
pumping device available for increased
efficiency in circulation and optimized seat
design - Cartridge unit factory assembled for easy
installation, which reduces down-time - Trouble-free long-term operation due to
heavy duty single seat design with bandage - Can operate under high sliding velocities
and high pressures - Can be adopted for use in compliance with
API 682, type ES - Versatile application for various kinds of
heavy duty applications
