CONSTRUCTION & SERVICING: The pumps are magnetic drive centrifugal pumps. Hence, there is no rotating seal to wear and allow the liquid being pumped to leak out. All pumps are serviceable with the use of a screwdriver or wrench. The only moving part other than the motor is the Impeller Assembly. This assembly rotates on a stationary shaft and up against a thrust washer. These are the only parts that can wear, and may need to be replaced. OPERATION: Pumps must be installed with a positive flooded suction, as they are not self-priming and will not produce a suction lift. March Pumps utilize the liquid being pumped to lubricate the Impeller Assembly rotating on the stationary shaft, and therefore they should not run dry. A carbon bushing on the 4 & 5 series will enable dry running protection. The direction of the motor rotation should be clockwise looking into the inlet of the pump. A trimmed impeller may be necessary when pumping a liquid with a specific gravity or viscosity greater than water as well in cases of high liquid temperature. AIR MOTOR INSTALLATION: Install a moisture trap, filter, and an automatic airline lubricator in the air line just ahead of the air motor. Use detergent SAE #10 automotive engine oil.
