N201D models are most commonly utilized in the marine industry, including applications of bilge, washdown, baitwell and general transfer. The compact size, bronze construction and stainless steel motor shaft offer many benefits. Choose from 12, 24 or 32 volt DC motor drive and neoprene or nitrile impellers. The impeller and cam can be easily replaced for better serviceability. Large vent openings separate the pump and motor.
Garden Hose Threads (External) & Pipe Threads (Internal) for Port Connections
Available with 12, 24 and 32 volt D.C. Motor Drive
Neoprene Impeller Standard (optional Nitrile Impeller - 04)
For Close Coupled AC Motor units, see Models 211D and 211M
Marine uses include Bilge, Washdown, Baitwell and General Transfer
Motor drive is clockwise facing pump end. Liquid flow direction is right to left facing pump end. Correct D.C. voltage must be supplied to motor - 12, 24 or 32 volts as specified on motor name plate.
Horizontal motor mountings - including sidewall mountings are recommended. The pump can be mounted in any of four positions 90o apart. Two screws attach pump to motor.
LIQUIDS & TEMPERATURES
Liquids compatible with neoprene can be pumped including fresh and salt water solutions and mild chemicals. Do not pump severe solvents or acids. When possible, flush pump with fresh water after each usage. Nitrile impellers can handle oil, contaminated water and kerosene at reduced impeller service life.
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, Permagard, and Dowgard. Rubber impeller pumps are not suitable for pumping gasoline or solvents.
Suction lift of 3 feet is possible when impeller is wet. Suction lines must be air tight in order for pump to self-prime. A foot valve at the beginning of suction line is recommended.
