Applications
Typical Applications for the N202M3 pump are for Engine Cooling. This flexible impeller pump is selfpriming and therefore, it is ideal for engine cooling. The bronze body and stainless steel shaft are well suited for marine environments. Liquids that are compatible with the neoprene impeller can be pumped including fresh and salt water solutions and mild chemicals. Do not pump gasoline, severe solvents or acids. When possible flush pump with fresh water after each usage. NBR impellers can handle oil contaminated water and kerosene, although it will reduce impeller service life. Extremes of cold and heat will affect impeller life. Limits of 40 degrees F to 140 degrees F should be maintained. Do not allow liquid in pump to freeze, and when not in use for long periods of time you can drain pump by removing drain plug provided, located at bottom of pump body. Use methyl alcohol based antifreeze compounds such as Zerex, Shell Sone, Pyro Permanent, Permagard, Dowgard. This flexible impeller pump can operate in either rotational direction. It combines the priming feature of positive displacement type pumps with the general transfer ability of centrifugal pumps. It will pump either thin or viscous liquids and can handle more solids in suspension than other types of rotary pumps. It operates at low or high speeds can be mounted at any angle and pumps in either direction with equal efficiency. Direction of shaft rotation determines inlet and outlet ports. Prior to installation, rotate the pump manually in direction of rotation to set flexible blades in direction desired.
