The Ultimate in Positive Displacement Pumps
for the Municipal, Industrial, Chemical and
Food Processing Industries

Double Disc Pumps™ combine the performance features of a positive displacement pump and the principle of “Induced Flow” to provide superior versatility in fluids handling. Based on a “Free Diaphragm™” technology, the pump utilizes a unique principle of operation where the discs perform the duties of both diaphragm and valve, providing a double acting, non-clogging, pumping action.


About Penn Valley Pump Company

Through continuous research and development we have created a range of positive displacement solids handling pumps that provide unmatched durability, reliability and performance compared with other positive displacement pump styles.

With thousands of units installed and operating in the Unites States alone, Double Disc Pumps™ are considered by many to be the premier product for feeding and transferring tough to handle sludges and slurries. We have achieved this level of acceptability by utilizing our extensive experience in the hydraulic and mechanical aspects of pumping installations to properly apply our equipment where it is best suited.
