Metaris Gear Pumps for Industrial Applications

Metaris has been supporting the industrial hydraulics industries for many years and has become a strong source for high quality hydraulic gear products.    Metaris pumps and motors are particularly suited for heavy duty mobile equipment applications.  They are designed for extreme duty cycles and continuous heavy duty operations.  The pumps and motors are a rugged design, but precision manufactured.

Pumps are available in single section units or several sections can be combined into one unit.  A wide selection of mounting flanges and drive shafts are available to fit most applications.  Pipe thread, "O" ring, or split flange are available in both metric and SAE standards.

Metaris pumps and motors are manufactured under strict quality control systems which are monitored by ISO-9001-2000 standards.


Section construction; Quality gear construction, high strength gray and ductile iron castings, repair components available throughout the world and a wide range of configurations to suit most applications.

Multiple pump units; Several pump sections or piggyback units can be combined on a single drive, to eliminate multiple power take-off drives.

Precision matched gears; All gear sets are designed, and machined from high alloy bar, surfaces are precision finished and each gear set is matched for maximum efficiency.  The 10 tooth construction gives maximum output per centimeter width per revolution.

Bearings; Quality roller bearings are utilized on journals to reduce the wear caused from contamination within the hydrualic system.

Bushing pumps; Bushings are constructed from quality materials and Teflon coated for maximum wear life.
