The HPE oil-cooled, premium efficient submersible solids-handling pump series from Pentair provides wire to water efficiencies resulting in substantial energy savings. The oil-cooled design runs up to 104 degrees F cooler than air-cooled pumps for longer motor life. Hydromatic seal leak probes provide early warning moisture detection to minimize unplanned maintenance costs. A shaft-grounding ring protects against VFD-induced currents to prevent premature bearing failure. They have quick disconnect cables, cartridge seals and terminal blocks, and permanently lubricated bearings, all designed to simplify maintenance and reduce downtime. 419/289-1144; www.hydromatic.com.
