MARCH PUMPS TE-7.5P-MD 7.5 Centrifugal Magnetic Drive Pump Instruction Manual
DESCRIPTION : Series 7.5 are centrifugal magnetic drive pumps. See the parts list for a breakdown of parts. Pumps are not self-priming, lack a suction lift, and thus require a flooded suction. Pumps cannot be run dry because the impeller requires the liquid being pumped for lubrication. The direction of motor rotation should be clockwise when facing the inlet of the pump. For liquids with a specific gravity greater than water, have a higher viscosity, or for elevated temperatures, a trimmed impeller may be necessary. For application assistance, contact March Pump.
MODEL ABBREVIATIONS : P Polypropylene, K: Kynar
ELECTRICAL: TE-7.5MD pumps are 1Ph dual voltage 115/230V 60Hz and 100/200V 50Hz, or 3Ph dual voltage 230/460V 60Hz and 190/380V 50Hz. Motors are totally enclosed fan cooled and are U.L. listed as well as rated for continuous operation. All motors have a conduit box for electrical connections.
ASSEMBLY & DISASSEMBLY: The magnetic coupling in the pump is strong enough to warrant caution. When servicing the pump, the attraction of the impeller magnet and drive magnet may pull the impeller from your grasp. When assembling, hold onto the outer diameter of the impeller vanes with both hands and gently engage the impeller into the magnet field. Hold the impeller firmly and resist the magnetic attraction as you slowly put the impeller back in. The magnetic forces are strongest between 1/3 to 2/3 of engagement and will diminish when the magnets become aligned. Do not allow the impeller to snap into the rear housing, doing so may result in damage. Exercise caution in placing any of the magnets near steel, tools, or other sensitive instruments as doing so may result in damage or personal injury. When attaching drive magnet to motor shaft, position the face of the drive magnet 5/32 inch above the face of the motor bracket.
