Our business began in 1961 as a representative for various pump manufacturers. The pumping industry was still emerging as newer technology was being developed. As time went on, we found the public was missing out on various new technological advances in not only pumps but in dredging equipment as well. We then transitioned into a manufacturer for pumps and now boast an inventory of over 75 different pumps and pumping systems.

As a "Woman Owned" business, we have successfully developed our business from small dewatering pumps to large industrial dredges and have dotted the world with our business products. We have a strong market demand on almost every continent and a continuous demand for all of our quality products. It is our mission here at Piranha Pumps to evolve and improve our products and services to accommodate the ever-changing global market and unique needs of our diverse customer base. We aim to lead the market with our competitive pricing and industrially advanced equipment while maintaining growth and customer satisfaction.
