"Sandpiper Pumps feature an externally serviceable air distribution system and all-bolted construction. Self-priming pumps can run dry without damage and are capable of deadheading against a closed discharge, eliminating the need for bypass or pressure relief valves. Seal-less design and corrosion-resistant materials make the pumps ideal for solids handling and high-suction lift applications such as transferring antifreeze, ATF, light viscosity petroleum and synthetic-based oil and waste oils.
