High throughputs
The extrex HV with 25% higher specific pumping volume, made possible by its special design, is recommended for standard applications - i.e. polymers that are not very or moderate temperature-sensitive and applications involving frequent colour and product changes.
Benefits
Longer gears permit a 25% higher specific pumping volume.
Design features:
- No dead zones
- Optimised flow inlet and oulet channels
- Optional temperature control thanks to heating medium
- Coolable shaft seals for low-viscosity polymers
- Interface-compatible with most 3rd and 4th generation Maag pumps and the extrex GP
