Use these self-priming pumps in water service

This company’s H Series of high-head self-priming centrifugal pumps are designed for a variety of water-related applications. Unlike standard end-suction centrifugal pumps, the H Series maintains its prime even if check valves or foot valves fail. The suction line’s location on the pump keeps the impeller and mechanical seal covered with water at all times, protecting the seal from dry-run, and eliminating the need for re-priming. The H Series pumps are available in models ranging from 3 to 20 hp. — Griswold Pump Company, Grand Terrace, Calif.
