The Pulsafeeder Eclipse represents a dramatic advance in pump technology. Combining proven design principles with patented features, our pumps are safe, simple, and reliable. Structurally rugged with corrosion-resistant materials, Eclipse is an ideal fit for many corrosive liquids. From acids to bases, we cover the entire pH scale. The innovative technology behind Eclipse supports its ability to handle the most corrosive chemicals with a simple-to-service, front pull-out design. Eclipse is available with wetted components in completely non-metallic construction and 316SS. These material offerings ensure corrosion resistance over a wide range of chemicals and process conditions. These pumps are magnetically driven to eliminate mechanical seal wear and leaks associated with rotating seals. The patented bearing design promotes constant lubrication.

Chemical Compatibility

Available in PVDF or 316-SS, Eclipse pumps ensure corrosion resistance against a wide range of chemicals, making Eclipse ideally suited to handle acids, caustics, polymers, flocculants, resins, solvents & scale inhibitors.


Exposure to harsh chemicals from a leaking pump can cause respiratory issues for employees. Magnetically driven sealless Eclipse pumps offer fewer points of failure. Zero leaks prevent harsh chemicals from damaging the pump, plant personnel or other equipment.

Simple Maintenance

With just a few moving parts, Eclipse’s patented front pull out design is reliable and easy to maintain. Easy access to the inner workings enables the pump to be maintained in place with a minimum number of tools – minimizing downtime and eliminating the need to move the pump to a repair shop. Pulsafeeder’s KOP (Keep-on-Pumping) kits provide all of the spare parts required to return the pump to as-new condition.


Eclipse was specifically designed to handle harsh chemicals, making it a viable alternative to other types of pumps.

Eclipse offers

Greater efficiency, reliability and lower cost-of-ownership than centrifugal pumps operating below B.E.PLess maintenance and greater reliability than peristaltic pumpsEclipse is ideal for applications where +/- 2% metering accuracy will suffice and accuracies of 1% or better are acheivable with a closed loop system, making Eclipse is an affordable alternative to diaphragm pumps.Eclipse’s compact design and pulse-free dosing results in a smaller footprint and reduced piping sizes.

Eclipse Metallic and Non-Metallic External Gear Pumps

Pulsafeeder Eclipse Series represents a dramatic advance in pump technology, with 12 different models for medium to highly corrosive liquids used in chemical processing, petrochemical, and water treatment. Typical applications that the Eclipse series is ideal for include acids, caustics, pH control, hydrogen peroxide, ammonia, and many more.
