Industrial pumps for demanding requirements – Conveying, dosing, supplying

MAAG Group gear pumps are running under the most demanding conditions in many processes all over the world. Their outstanding reliability is a result of more than 100 years of experience. The expertise gathered over those years allows us to quickly and reliably configure gear pumps specific to your requirements.

The robust design of the MAAG gear pump, featuring product-lubricated bearings, allows for performance and reliability in the most difficult conditions including corrosive and abrasive media, high pressure, high viscosity, and high temperature. The mechanical components of every gear pump meet very high accuracy standards making them perfect for precise dosing applications. Conveying applications require a steady throughput under varying pressure conditions making them an ideal match for gear pump technology. Our optimized flow channels and unique design also make our gear pumps the perfect choice when it comes to supplying high-viscosity product from high pressure or vacuum feed.

Industrial applications for external gear pumps

Carbon Fibres

MAAG pumps typically serve as a dope feed or transfer pump in processing the carbon fibres. Considering the Polyacrylonitrile (PAN) in DMAc Solution, with about 20% of PAN in 80% solvent like DMAc (Dimethylacetamide) or DMSO (Dimethylsulfoxide), also consisting other components and small amounts of water, the mixture has to be pumped through a tiny injector into a chamber where the solvent evaporates and a solid fibre is left. For this purpose, MAAG pumps are designed to convey and dose the solution with the high efficiency.

Gum Base

Processing of gum bases (elastomers, resins, waxes, fats, emulsifiers, fillers and antioxidants) involves several stages such as melting of the gum base, mixing other ingredients and rolling of finished gum. Here, MAAG pumps typically serve, as transfer pumps or as booster pumps in each stage.

Hot Melt

For hot melt adhesives used primarily for packaging, textiles, labels, tapes, pressure sensitive applications and other disposable products like stamps, MAAG provides metering, transfer, loading and booster pumps. For instance, in front of a spray nozzle.

Molten Sulfur

Its production is ever increasing in refineries, natural gas plants, sulphuric acid plants, chemical production such as rubber additives or even in food products. It is also rapidly reaching new industries. Hence, safe handling of molten sulfur and the associated hydrogen sulfide emissions is becoming critical. MAAG pumps usually aid as High Temperature transfer pumps for such precarious applications.


For this application, MAAG pumps are used as a Spinning or Dosing pumps. Spandex or elastane is a synthetic stretchy chemical fibre known for its exceptional elasticity. It exhibits properties similar to rubber, but is more solid and significantly more durable. Possessing viscosity of up to 1,000,000 mPas, the entire process requires a short dwelling time and is carried out under nitrogen (N2) because the medium reacts to oxygen. MAAG pumps with their special inlet and seal design fulfils the necessary requirements of all stages.

Vinyl Alcohol

The production of Ethylene vinyl alcohol copolymer (EVOH) is a two-step process of polymerization and saponification. Ethylene and vinyl acetate are polymerized using an initiator/ activator complex. MAAG pumps serve as a transfer pumps for all stages in the process.


MAAG offers customized solutions with special bearings, special sealing designs for applications such as Grease lubrication, lubrication by liquid oil or atomized oil (oil mist), or even pressurized pure oil lubrication to meet adverse requirements in terms of pressure, viscosity and temperature.

Flavours & Fragrances

Usually a mixture of raw products (fruits, herbs, etc.) and a base solvent (alcohol, acids, etc.). When it comes to manufacturing aromas, it’s all about the highly  accurate dosing of low viscosity scent and aroma components. MAAG pumps serve as low viscous distillate removal and corrosive residue removal pumps or serve  as dosing pumps to accurately dose flavor additives into perfume.

Food & Pharma

MAAG can offer food-compliant pump executions with stainless steel housings/shafts, ceramic bearings and FDA certified sealings. With their good priming capability, MAAG pumps are well suitable in the pharmaceutical process where the temperatures vary widely, media have low viscosity and accuracy of flow rates  is extremely important.


The chemical industry is one of the most important economic sectors. It is the foundation and engine for new and innovative products and materials. The manufacture of chemical base substances as raw materials for plastic products, food and chemical poducts calls for the highest standard of precision and care.
