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

Trust Zenith for Your Metering Solutions
Engineered Pump Solutions to Dose Your Ingredients
Whether you are spraying, blending or injecting your fluid material, repeatability is of paramount importance. Zenith products assure accurate metering over a wide range of applications and process fluid conditions. Add a drive system and incorporate a closed-loop speed controller to maintain metering accuracies of +/- 1 percent.
In addition to accurate delivery, close tolerance precision gear metering pumps with only two moving parts are reliable in service and have virtually pulse-free fluid performance. A gear metering pump’s tight internal clearances are as small as 50 millionths of an inch, ensuring a consistent flow rate and high-pressure capabilities where they are needed the most.
Delivering engineering and design expertise for solutions that address unique process requirements and save time and money.
