The Double Diaphragm (DD) series pump is one of our company’s signature pumps and is the first pump we began manufacturing.
Our patented Double Diaphragm pump has become a staple with site and utility contractors. The DD series pumps are unique because of the continuous run capabilities, very low fuel consumption, wide variety of dewatering applications and the ability to handle large solids with ease. Our DD Series pumps have become a benchmark for diaphragm pumps. The DD series pumps are excellent for: Open pit dewatering, Kelly wells, pumping out manholes, cleaning cesspools and septic tanks, small sock-drain, and small well-point systems. Our newest pump to the fleet is our DD-4S Barge pump.
