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 downtime - Trouble-free long-term operation due to
heavy duty single seat design with
bandage - Can operate under high sliding
velocities and high pressures
