HPE Series oil-cooled, premium efficient submersible solids-handling pumps from Pentair are designed for long motor life and low maintenance cost. Premium efficient motors provide wire-to-water efficiencies resulting in energy savings. The pumps’ Hydromatic seal leak probes provide early warning moisture detection to minimize unplanned maintenance costs. A shaft-grounding ring protects against variable-frequency drive-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.
