Maag Pump Systems – a strong brand within the MAAG Group

Whether gear pumps, extrusion pumps, transfer pumps, pressure pumps, chemical pumps, industrial pumps, metering pumps – MAAG is a leading manufacturer of gear pumps of all kinds for the polymer, chemical, petrochemical, pharmaceutical and food industries worldwide. Filtration systems for polymer production and processing are the second area of focus.

Within the MAAG Group, MAAG is the lead brand for pump systems and filtration systems. Manufacturers of chemical products as well as plastics, hot melt, polymers and polymer compounds and other low and high viscosity products worldwide rely on MAAG pumps and filters. More than 100 years of experience in processing, together with in-depth know-how in polymer processing, make MAAG a strong partner, and the MAAG Group as a whole a leading international partner to industry.

The company’s history began in 1913, with inventor Max Maag. Between 1918 and 1928, Maag successfully registered a number of patents for gear pumps. The business continually set new standards: in 1959, with the construction of what was then the largest gear grinding machine for straight and helical gears up to 4,600 mm in diameter, and the construction of a gear clutch that can be switched at standstill for power transmission of 100,000 hp at 428 rpm; in 1964, with the construction of what was then the largest turbo transmission, featuring power transmission of 85,000 hp at 3,000/1,000 rpm; in 1990, with the construction of the world’s largest gear pump, the PR 41-6 …

Technical edge: Pumps and filtration systems from MAAG

MAAG is one of the world’s leading manufacturers of gear pumps for high-end chemical and industrial applications, for polymer production and processing, and for rubber production. Plastics and chemical products can be efficiently processed with Maag pump systems. MAAG gear pumps reveal their full potential especially in difficult process conditions where high pressures, viscosity and temperatures occur simultaneously. MAAG filtration systems, which reliably clean plastic melts in production and extrusion, ensure the purity – and so the quality – of the customer’s final product.

As part of the global MAAG Group, MAAG supports the international plastics, pharmaceutical and chemical industries with technical know-how and high-quality systems in the economical production of polymers and other media.

What MAAG customers of the MAAG Group say:

The x6 Maag pump guarantees increased production capacity compared to the same size of pump of our competitors

several customers

Lower pump size, lower weight, lower rotation speed and higher specific volume against competitors was main argue to convince to select Maag.

Industrie Polieco

One of our extrusion pumps had developed a seal leak after 19 years of great service, so we sent it in for evaluation and repair. Maag’s service and maintenance team bent over backwards to get me my pump back before our start-up of a critical line. The communication and service was some of the best I have experienced in my maintenance career.
