ZENITH H Series
Ensuring reliable flow control in high-temperature and viscosity applications.
MFG in Monroe, NC USA
The tough and wear resistant H series Zenith pump series is designed for high temperature and viscosity service. The H series pumps provide precise, pulse free, repeatable flow in market segments such as adhesives, additives, polymers, plasticizers, oils, tars, inks and fibers.
Precision Gear Pumps
Product Performance You Can Rely On
Precision gear pumps are an integral part of many manufacturing processes requiring metering, mixing, dispensing, coating, and extruding, where accuracy and uniformity of flow are critical. That’s why manufacturers in industries from manmade fibers and polymers to food and medical devices have relied on Zenith gear pumps since 1926. With high metering accuracy, pulse-free flow, and long wear life across a wide range of fluid and pressure conditions, the Zenith Pumps brand is synonymous with high performance and reliability.
In addition to standard product offerings, Zenith can provide custom-engineered pumps for demanding services, such as submersible, flushable, and sanitary applications. Backed by the resources of CIRCOR Engineered Systems group, Zenith Pumps can provide a complete custom-engineered system along with the pump, from the tank to the controls, letting you focus on your core competency while we develop a fluid handling, mixing, or metering system aimed at providing the highest precision and reliability possible.
- Extremely precise and repeatable metering.
- Flow stays near constant without need for expensive flow meters and control systems.
- Metering under extreme operating conditions, such as high viscosity, high temperature, high pressure.
- Pulse free metering and dosing
