German-Engineered Equipment for Endless Applications

With over 150 years of proven industry innovation, Mahr Metering Systems has been a leading supplier of durable meter mix solutions across multiple applications. Mahr Metering Systems has a proven track record providing meter mix solutions for multiple applications in aerospace and aviation, automobiles, extrusion, medical equipment, personal care products, pharmaceutical and medical manufacturing, and textile manufacturing. Our machines can perform in any environment from general purpose to Class 1, Div 1, as well as virtually any material from food grade to liquids and powders. With unmatched versatility, both our standard machines and customized solutions combine state-of-the-art technology with German-engineering designed to last.

FILLING

Mahr Metering Systems has two products designed for filling applications. Our MarDrum is a drum pump system developed by Mahr especially for low and medium viscous liquids. It is used for refilling automatically the buffer tanks of our meter/mix-machine MarMax. Due to the pneumatic liftstand and the use of dollies a drum change is very easy and almost no contamination occurs.  While our MarDrum 200 hv is available for emptying 200 l drums filled with high viscous liquids. A platen, optionally heated, is pushed onto the surface of the liquid and a gear pump can consequently meter the product.

COMPOSITE AND LIGHT WEIGHT

Composites are now being used in vehicle and equipment applications, including, panels, frames, interior components and other parts. Some composite infrastructure applications include buildings, roads, bridges and pilings.  Mahr offers turnkey systems and precision gear pumps to accurately meter, mix and dispense the materials used to make lightweight composites.

PRESSURE INCREASE/STABILIZATION

Mahr MarEx inline transfer pumps to stabilize and boost pressure for polymer transfer and processing in various industries. Generating pressures up to 7,000 PSI at a constant rate with a metering accuracy +/- 1%. Regardless of inlet pressure the Mahr pump has the ability to stabilize or boost pressure in extreme conditions.

EXTRUSION

Mahr’s Inline gear metering pumps are used in extrusion processing and have single stream pumps mounted in-line with the tubes. Our inline gear metering pumps have options for high wear-resistance, larger flow rates, combination of resistance to wear and corrosion, and use for chemically aggressive media.    Because of the in-line mounting no additional pump block is necessary and various coating technologies enlarge the application possibilities of the used base materials. Furthermore, a coating reduces friction, wear and corrosion.

LIQUID METERING

Wherever precise mixing and dosing is required, the standard series of MarMax meter mix dispensing machine is typically used.  Common applications of the MarMax meter mix equipment include single- and multi-component adhesives and resins, thermosets, thermoplastics, polyurethane, plastics, adhesives, chemicals, composites, and converting.  Our MarFin Spin Finish Gear Metering Pumps are also extremely precise, especially for fast spinning processes that allows for better properties for further processing and an exact metering of the finish for each product stream is assured. In general, each of the products can be used for dosing liquids however, the operating conditions limit the selection.

FOIL LAMINATE

Laminated foil is a thin gauge ferrous and non-ferrous metal laminated to a variety of materials including Polyester (PET), Polypropylene (PP), and Polyethylene (PE). Foil lamination enhances the product integrity and also increases vapor barrier characteristics. Mahr offers turnkey systems and precision gear pumps to accurately meter, mix and dispense the materials used to make laminated foils.

FOIL EXTRUSION

Products produced by continuous extrusion include structural shapes (window frames, shower stalls, channels), tubes and pipes, and rods of various cross sections. Products made by discrete extrusion include toothpaste tubes, aluminum beverage cans, and battery cases. Mahr offers turnkey systems and precision gear pumps to accurately meter, mix and dispense the materials used to make products produced by foil extrusion.

FIBERS AND FILAMENTS

Fibers and filaments most commonly used in industrial applications include carbon fiber, glass fiber, and synthetic fibers for making textiles and composites.

The most important application of polymer fibers and filaments is in textiles. Their use as reinforcing materials in plastics (composites) is a growing application, but still small compared with textiles. Mahr offers a complete line of positive displacement precision gear pumps for the fiber and filament industry including:

  • Melt spinning
  • Dry Spinning
  • Wet Spinning

SPIN FINISH PROCESS

For use in Spin Finish Processing, Mahr recommends the MarFin Spin Finish Pumps for extreme precision, especially for use in liquids like antistatic finish and adhesive additives or other additives.  The Mahr MarFin Spin Finish Pump can avoid fiber breaks or electrostatic charging that allow fibres to get a better elasticity, as well as better properties for the further processing. An exact metering of the finish for each product stream is assured and are applicable in a variety of applications in different industries to meter.

ADHESIVE APPLICATION

Chemically curing adhesives are reactive materials that require chemical reaction to convert them from liquid (or thermoplastic) to solid. Once cured, these adhesives generally provide high strength, flexible to rigid bond lines that resist temperature, humidity, and many chemicals. Mahr offers turnkey systems for meter, mix and dispensing as well as a complete line of positive displacement precision gear pumps for fiber and filament industries including:

  • Spray adhesives
  • Fabric adhesive
  • Epoxy
  • Polyurethane
  • Synthetic resin and rubber adhesives
  • Nonstructural caulking components
  • Natural based glues and adhesives
  • Structural sealants
  • Pressure sensitive adhesives
  • Mattress Adhesive technologies
  • Hot melt adhesives
  • Fabric industry
  • Carpentry
  • Yellow wood glue
  • Office and stationary
  • Medical Use

URETHANES & POLYURETHANES

Urethanes are used for a wide range of applications to gain stronger, tougher, more durable and more versatile products. These products have high load bearing capacity in tension, compression and shear. Mahr offers turnkey systems as well as a complete line of precision gear pumps to accurately meter, mix and dispense various urethanes and polyurethanes for compounding the following types of urethanes and applications:

  • Flexible Polyurethane Foam
  • Rigid Polyurethane Foam
  • Coatings, Adhesives, Sealants & Elastomers [CASE]
  • Thermoplastic Polyurethane [TPU]
  • Reaction Injection Molding [RIM]
  • Binders
  • Waterborne Polyurethane Dispersions [PUDs]
