Penn Valley Pump – Double Disc Positive Displacement Pumps

The Ultimate in Positive Displacement Pumps

Company Description:

Penn Valley Pump Company, Inc. has been developing, manufacturing and marketing Double Disc Pumps™ for the municipal, industrial and chemical industries since 1980. 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.

 

 

When you purchase a Double Disc Pump™ you buy our long term commitment. We size a unit specifically for your application, selected by engineers with over 45 years combined experience in designing, engineering, manufacturing and applying this exciting technology.

Technology Description:

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-Disc” 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.  

Through an arrangement of connecting rods and a camshaft, a reciprocating action of the discs is created, forming a large cavity between the discs. This cavity is filled and exhausted in a continuous flow.  

The large valve like discs mean that solids and rags can be handled without loss of pumping action. The valve like discs have large seating areas that provide for low internal velocities, extending the pump wear life on abrasive sludges and slurries.  

The fluid chamber is sealed with flexible trunnions which eliminates packings, mechanical seals, and requires no flushing water or other forms of lubrication. The large diameter discs are proven to handle large solids, rags, plastics, etc., that would cause other pumps to fail.

Technology Strengths, Weaknesses and Critical Indicators

NOTE: There are multiple technologies that are used as part of integrated manure management systems and yet are not manure management types on their own. The impact of these technologies on their own would be minimal or very difficult to quantify.

General Support & Other:

  • Can be an integral part of many manure management systems
  • Most projects have at least some equipment that supports operations of the main technology
  • This technology is not evaluated on its own, the NEAT Matrix for this technology is neutral unless utilized with other technologies.

Newtrient Comments/Opinions:

Newtrient will continue to work with Penn Valley Pump Company to further refine the cost and performance information as more information becomes available and as new commercial dairy installations come on line.
