Pentair Flow Technologies has introduced the BERKELEY DRY-RUN Seal System™ as an option for BERKELEY® centrifugal pumps to help protect against friction and head damage. The system protects against damage by providing continual lubrication to the mechanical seals and can be used in applications such as irrigation systems, rental fleets and construction dewatering. The company said that when a pump must run dry for several hours, it loses its prime without being shut off, or requires extended time for priming, and 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 is designed to prevent "costly damage" by providing continuous lubrication to essential pump components. Jim Hughes, vertical marketing manager for Pentair, said: "The DRY-RUN Seal System consists of four integrated components.
"Together, they provide superior protection against heat and friction damage to your pump investment." These components include: DRY-RUN Gland, which surrounds shafts and channels a continuous flow of lubricant to shaft and mechanical seals to cool and minimise friction.
Other benefits include mounts in both CW and CCW pump configurations and a Lubricant Reservoir, which supplies lubricant to the DRY-RUN Gland through pumping action created by rotating shaft. www.berkeleypumps.com
Intelligent pump cleaning reduces ragging in Ireland
The installation of an AC drive with an advanced software tool has dramatically cut call-outs for blockages at an Irish County Council pumping station. Control Techniques' IPC Lite software has been fitted to a replacement Commander SK AC drive at a pumping station at Kelly's Bay, Skerries in North County Dublin, Ireland. The delivery is said to have cut callouts from 'ragging', the fouling of the pump's impeller, from a weekly occurrence to just once since it was installed six months ago.
