March Pumps TE-7.5-MD Series Manual

DESCRIPTION & OPERATION: 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 rotati on 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: K: Kynar, P: Polypropylene
ELECTRICAL: The motor is 3 phase 208-230/460 Volt 60 Hz, 190/380 Volt 50 Hz. The motor is
CSA listed and rated for continuous duty.
CAUTION IN 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 t he 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.
