Pulsa Hydraulic Diaphragm Pumps
We built the foundation of Pulsafeeder on the Pulsa Series® of hydraulic pumps for industrial applications. For over 70 years, Pulsa hydraulic diaphragm pumps have been synonymous with dependability, quality and precision engineering, and our customers still depend on these chemical dosing pumps to provide years—even decades—of year round operation.
Available with a variety of diaphragm styles that deliver everything from thin fluids to lime slurries, our hydraulic pumps are constructed for contact with the most hazardous chemicals with features and options to provide safe, remote, and accurate dosing. Count on Pulsa Series hydraulic diaphragm pumps from Pulsafeeder for the most demanding applications.
Pulsa hydraulic diaphragm pumps are widely used in the following industries: chemical processing, petrochemical, oil and gas, water and wastewater treatment, and power generation.
