The N211D impeller pump models meet the U.S. Coast Guard ignition protection requirements (33CFR 183.410). Bronze construction and stainless steel motor shafts help ensure corrosion resistance over time. A convenient carrying handle, sealed and grounded 3-conductor plug-in cord and garden hose threads for external and pipe threads for internal port connections can all be found on the N211D.

Motor drive is clockwise facing pump end. Liquid flow direction is right to left facing pump end - see dimension drawing. Motor is 1/6 HP, 1725 RPM, 115VAC, TENV.
DO NOT RUN DRY - Neoprene impellers generate high rubbing friction unless lubricated by liquid being pumped. Lack of liquid will cause impeller to burn up. Standard impeller in Neoprene (04), optional Nitrile impeller (05) available.
LIQUIDS & TEMPERATURES
Liquids compatible with neoprene can be pumped including fresh and salt water solutions. Do not pump severe solvents or acids. When possible, flush pump with fresh water after each usage. Extremes of cold and heat will affect impeller life. Limits of 40°F to 180°F should be observed. Do not allow liquid in pump to freeze. Drain pump by loosening cover screws. Use methyl alcohol based anti-freeze compounds such as Zerex, Shell Zone, Pyro Permanent, Permaguard, and Dowgard.
Suction lift to 15 ft. for model 211D is possible when impeller is wet. Suction lines must be air tight in order for pump to self prime. Always use foot valve at beginning of suction line to keep suction line full and impeller wet.
