MAAG Gear Pumps Extrusion Booster Gear Pumps for the Elastomer Processing Industry - extrex ER

Elastomer processing requires positive displacement pumps to gently convey high-viscosity rubber through the system. 

The specially designed low-compression teeth of the extrex⁶ ER extrusion gear pumps meet high-pressure and low-shear 

requirements for conveying, boosting, or metering gear pumps.

The extrusion gear pump delivers rubber compounds at a constant, precise flow rate even at high discharge pressures. It is also suitable for handling dry or viscous compounds, where previous generation extrusion pumps have reached their performance limits due to scorching. Furthermore, the reduced internal friction improves sustained high efficiency and service life.

Your ideal partner, innovative in traditional technology to meet the demands of chemical and industrial processes, demands tailor-made solutions and adaptable products. With pumps manufactured from modular components, Maag has found a way to combine attractive price points with short delivery times. Achieving this level of performance exemplifies the progressive thinking that has characterized our corporate culture since its inception. Another benefit of modularity is that all components are field-proven for reliable, long-term operation. Our global service network provides expert technical advice to ensure uninterrupted machine operation. Whatever your process requirements, whether involving pressure, temperature, or viscosity, a Maag pump system is the right choice.
