Precision Metering

Zenith gear metering pumps have a simple internal structure and advanced processing technology. All internal pump components 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 Zenith 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 and general chemical industries; it is also used in tobacco, brewing, beverages, and food industries for metering auxiliary materials such as flavors, vitamins, and food colorings to ensure product quality and control production costs.

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 outlet. At the outlet, the meshing of the gears reduces the enclosed space, thereby extruding the material out of the pump. Thus, gear pumps do not have check valve mechanisms. This structural feature makes gear pumps most suitable for metering and conveying high-viscosity fluids, overcoming issues in reciprocating pumps like piston or diaphragm types, where check valves can stick or fail to close properly at high viscosities, leading to reduced pump efficiency, inaccurate metering, or even failure to operate. Zenith gear metering pumps can be used in the production of hot melt adhesives, adhesives, and polymer products. They are also extensively 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/plastic products.
