●Independent of direction of rotation
●Variant with PTFE secondary seals for high chemical resistance (M78N)
Advantages
●Universal application opportunities
●Efficient stock keeping due to easily interchangeable faces
●Extended selection of materials
●Insensitive to low solids contents
●Flexibility in torque transmissions
●Self cleaning effect
●Short installation length possible (G16)
●Pumping screw for media with higher viscosity (M7..F)
