Precision Metering

Mony gear metering pumps have a simple internal structure and advanced processing technology. All internal pump parts are precision ground, with dimensional errors controlled within 0.0005", ensuring minimal internal clearance to improve volumetric efficiency, guarantee output flow accuracy, and reduce the impact of external working condition changes on metering precision. Utilizing the accuracy of Mony metering pumps, various additives can be precisely metered and uniformly injected into corresponding chemical raw materials for the manufacturing of final products. This application is widely used in pharmaceuticals, cosmetics, detergents, papermaking, petrochemicals, rubber and plastics, paint manufacturing, polyurethane, and other fine chemical and general chemical industries. It is also used in tobacco, brewing, beverages, and food industries for metering auxiliary materials such as flavorings, vitamins, and food colorings to ensure product quality and control production costs.

Coating Process

Compared to various other metering pumps (piston pumps, diaphragm pumps), gear metering pumps have a pulse-free output characteristic, making them particularly suitable for coating processes. Currently, Mony gear metering pumps are widely used in the production of photographic film, photographic paper, and PS plates for printing to spray photosensitive emulsions, as well as in the production of magnetic tapes, disks, and IC cards to spray magnetic slurries, meeting the high-quality requirements of these products for coating processes. At the same time, this characteristic is also used for surface spraying, such as in the automotive industry. Specially designed Mony gear metering pumps can also feature quick cleaning, meeting the requirement for rapid coating changes during production.

Metering and Conveying of High-Viscosity Materials

The working principle of gear pumps involves a pair of meshing gears and the pump body forming enclosed gear spaces, transferring material from the pump inlet to the pump outlet. At the outlet, the meshing of the gears reduces the enclosed space, thereby extruding the material out of the pump body. As a result, gear pumps do not have check valve mechanisms. This structural feature makes gear pumps most suitable for metering and conveying high-viscosity fluids, overcoming the issues of reduced pump efficiency, inaccurate metering, or even failure caused by check valves sticking or not sealing properly in reciprocating pumps like piston or diaphragm pumps when handling high-viscosity materials. Mon gear metering pumps can be used in the production of hot melt adhesives, adhesives, and polymer polymerization products. They are also widely used in other industries, such as self-adhesive labels, tapes, automotive windshield bonding, engine cylinder head seals, and the industrial production of electronic components and rubber and plastic products.
