The tough and wear resistant Zenith H pump series is designed for high temperature and viscosity service, providing stable, repeatable flows which are assured even under varying conditions of pressure. They feature a unique design that offers pulseless flow without valves or any flexible elements that could negatively impact performance.
With only three moving parts, the Zenith H pump series’ hardened tool and die steels rate to 64 Rc or better, and easily-replaceable sleeve bearings are available for affordable rebuilds. They also provide high volumetric efficiency, which is achieved with optimum operating clearances and supported while under pressure by built-in alignment dowels. The construction is of the highest precision standards, and all of this with a high temperature tolerance that can handle up to 950°F (510°C)!
The Zenith H pump series provides precise, pulse free, repeatable flow in market segments such as adhesives, additives, polymers, plasticizers, oils, tars, inks and fibers.
