for plastic melt
The extrex GP is recommended for standard applications, i.e. polymers that are not very or moderately sensitive to temperature and shear forces, as well as applications with frequent colour and product changes.
The special SE (sensitive) design allows even temperature-sensitive or cross-linking products to be transported. In this case, a part of product, used as a lubricating flow for the bearings, is actively conveyed outside to ensure highest product quality.
No dead zones
Optimised flow inlet and outlet channels geometries
Temperature-controll thanks to heating medium across the internal network of tempering channels
Coolable shaft seals for low-viscosity polymers
Interface-compatible with 3rd and 4th generation Maag pumps
