Cost-efficient retro-fitting of an existing extrusion or compounding line calls for well-thought modifications to the control technology. The maax® 3 automation system developed by maag is directly integrated into the frequency converter of the pump. It is the ideal solution for retrofitting extrusion lines with gear pumps in a cost-efficient manner. Operation, control and regulation are simplified. This guarantees an optimum protection and operation of the gear pump. The process and operation reliability of the entire plant are increased.
Maax® BF is Maag’s well-proven control system for the fully automatic backflush Screen changers. It allows the processor of highly contaminated polymer melts a simple handling of the backflush screen changer and a fully automatic screen cleaning and manifold use of the screens. The automation system is particularly well suited for retrofitting extrusion lines with screen changers with backflush function. Operation, control, and Regulation as well as monitoring of operating parameters are simplified. Process and operation reliability of the entire system are increased.
It simplifies operation, control and adjustment of the operating parameters. This guarantees optimum protection and operation of the gear pump and screen changer. Process and operational reliability of the entire system is increased. The maax® 100S automation system is the ideal solution for integrating melt pumps and screen changers. maax® 400S is for upgrading coextrusion lines. The maax® 600S automation system is the ideal solution for equipping complete and complex extrusion and compounding plants.
Magnetic drives are hermetically sealed thereby guaranteeing that environmentally hazardous, poisonous, and malodorous substances are pumped safely. The product chamber in the gear pump is completely separated from the environment by a containment shell. The torque is transferred from motor shaft to pump shaft without contact by means of heavy-duty permanent magnets. This design makes the magnetic couplings extremely safe and virtually maintenance-free.
Maag specializes in the design and application of blendrex® heat exchangers used to preheat polystyrene melt prior to devolatilization and to cool polyester prior to spinning or pelletizing. blendrex® heat exchangers are problem solvers for many types of difficult heating and cooling applications.
High reliability and functionality are crucial for a seal in the polymer discharging process for guaranteeing optimized product quality and line availability. The vispac® shaft seal is known for its robustness, reliability and especially for its easy handling. This low-maintenance seal is a proven combination of the viscoseal system and sealed stuffing boxes.
The seal is applicable for high temperatures. A different material combination is available for aggressive and corrosive media. The Sealing ring in SSiC can be used for abrasive fluids.
The Double Mechanical Seal is a Maag brand. It has a robust design with buffer fluid. Therefore, it is suitable for corrosive and abrasive applications. The sealing rings are available in carbon and SSiC (sintered silicon carbide ceramic).
Magnetic Couplings with our double containment shell. It provides a hermetically sealed design and is virtually maintenance free. In special designs for applications with suction pressures up to 200 bar.
The single mechanical seal with balanced sealing ring can be used for high inlet pressures and needs to be used in combination with balanced shaft (double extended shaft, two seals).
The double mechanical seal with balanced sealing ring can be used for high inlet pressures. It needs to be used in combination with balanced shaft (double extended shaft, two seals).
The viscoseals are available for high viscous fluids. The seal is contactless and dynamic. It has a simple design and is only one sealing part. A cooled execution is available and it is virtually maintenance free.
The viscoseal is combined with two buffered lip seals. It provides a dynamical sealing during operation and the buffered lip seals provide a static sealing at standstill.
Packing glands in various executions. Without adoptions in the modern sealing technology not widely used any more. It is available in a buffered execution.
The lip seals can be used for either negative or positive suction pressures. depending on the mounting direction. These are mainly used for lupe oil application. Furthermore execution with ball bearing supprt for coupling the drive shaft with gear shaft directly. The price and the easy substitution are the advantages of the lip seals.
