Standard Duty Non-Metallic Pumps are ideally suited for intermittent / on-demand, portable, moderately abrasive fluids, and suspended solids. Standard duty pumps are constructed in Aluminum, Cast Iron, Stainless Steel and non-metallic materials such as PTFE, Polypropylene, and PVDF with elastomer TPE (thermal plastic elastomers) and PTFE options in diaphragms and check valves. These air operated diaphragm pumps are also known as sealless pumps.
Founded in 1965, Warren Rupp pumps are manufactured in aluminum, cast iron, stainless steel, Hastelloy equivalent, Polypropylene and conductive Polypropylene, PVDF and conductive PVDF, nylon and conductive acetal. Self-priming and sealess, they are ideal for pumping abrasive, semisolid, corrosive and shear sensitive materials. They are also chosen for applications where electricity is not available, or cannot be used due to safety conditions. Diaphragm pumps provide pollution-free and energy-efficient operation, with fewer moving parts than conventional motor-driven pumps.
