Series TE-7.5-MD Pumps w/1 Phase Motor
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 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:
K: Kynar, P: Polypropylene
ELECTRICAL:
The motor is 1 phase 115/230 Volt 60 Hz, 110/220 Volt 50 Hz. The motor is U.L.
listed and rated as 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 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.
