DELAVAN, WI — May 16, 2010 —Pentair Flow Technologies is introducing the BERKELEY DRY-RUN Seal System as an option for BERKELEY® centrifugal pumps. The DRY-RUN Seal System protects against damage by providing continual lubrication to the mechanical seals; and is ideal for demanding applications such as irrigation systems, rental fleets and construction dewatering.
When a pump must run dry for several hours, loses its prime without being shut off, or requires extended time for priming, heat and friction can build up to the point of destroying seals and damaging the pump. When these conditions cannot be avoided, the DRY-RUN Seal System can prevent costly damage by providing continuous lubrication to essential pump components.


Integrated Components Protect Pump Investment

The DRY-RUN Seal System consists of four integrated components” said Jim Hughes, Vertical Marketing Manager for Pentair. “Together, they provide superior protection against heat and friction damage to your pump investment.” These components are:
1.      DRY-RUN Gland – Surrounds shaft; channels a continuous flow of lubricant to shaft and mechanical seal to cool and minimize friction. Mounts in both CW and CCW pump configurations.
2.      Lubricant Reservoir – Supplies lubricant to the DRY-RUN Gland through pumping action created by rotating shaft. Circulating lubricant transfers heat away from shaft & seals to the reservoir. 
3.      Mechanical Seal – Provides containment of lubrication.
4.      Shaft Sleeve – Replaceable hardened stainless steel sleeve provides the ideal surface finish for lip seal operation.
The DRY-RUN Seal System, as well a full line of BERKELEY brand pumps, motors and controls, are available through a network of more than 5,000 authorized dealers throughout North America. More information on the DRY-RUN Seal System, including where to buy, is available at
