Magnetic Drive Pump
MATERIALS
B - Polypropylene
C - PVDF (Kynar)
Penguin magnetic-driven pumps are designed to handle a large range of chemicals without diffi culty. Constructed of polypropylene, kynar,
Series M pumps have an upper working temperature of 190/220/250 degrees, respectively, and thus can handle highly corrosive or mild
chemicals, acids or solvents. Series M pumps eliminate the conventional shaft seal found in most pumps. This means that there is no rotating
seal to wear out and allow the liquid being pumped to leak out. The pumping action may eventually fail, however, the liquid can never leak
out. Series M pumps are easy to install and operate, and are virtually maintenance free. All pumps have been tested for proper operation
before leaving the factory. To obtain optimum service life, please follow all instructions.
Install the pump as close as possible to the liquid reservoir from which the liquid is being pumped. As more energy is necessary to prime the liquid than to
discharge the fl uid, make the suction as short as possible.
Always make sure there is enough liquid in the reservoir and the level is high enough considering the capacity of the pump unit. Inadequate liquid will cause
vortex in the reservoir. A vortex occurs when air mixes from the surface into the fl uid. This can disturb the fl ow and also prevents the pump from priming.
Never run the pump for more than 5-10 minutes against a closed discharge valve. This will cause overheating of the fl uid in the pump and will damage the
polypropylene parts. Temperature in this case will increase up to 220 degrees. If the pump is being run against a closed discharge valve for a long duration
of time, install a small bleed line back into the reservoir before the discharge valve of the pump. If the line is small, there is a minimum pressure loss. This
prevents overheating by recirculating the fl uid.
Model MTD-1/14 and M-1/8 pumps are supplied as standard in a single phase, single voltage, 115V, 50/60c motor with 230V as an option. All other models
supplied with a single phase are dual voltage, 115/230V motors. The factory wires all dual voltage motors for the lower voltage (115V) unless otherwise
requested. When changing from 115V wiring to 230V wiring, follow the motor manufacturer’s wiring instructions, which are found in the motor junction box or
motor label. Be sure to wire the motor for clockwise rotation as viewed from the suction entrance of the pump. A power cord and plug are supplied for immediate
plug-in operation on motors wired for the lower voltage. These motors have already been wired at the factory for proper rotation. A plug is not supplied on
motors wired 230V. Motors supplied in three-phase are dual voltage, 230/460V, 50/60c which are not wired at the factory. Since direction of rotation cannot
be determined without operating the pump, the motor rotation must be checked before operation. Attach leads to motor and bump start. Since these pumps
must not run dry for more than 10 seconds, do not leave motor running. As viewed from the suction entrance of the pump, check for clockwise rotation. If
counterclockwise rotation, change any two leads and check rotation again. Many options are available on the M Series motors including explosion-proof and
special voltage motors. If any of these options are required, please check the motors carefully or consult factory.
It is recommended to enlarge the suction line a minimum of one size larger than the suction entrance. Never reduce plumbing on the suction. Avoid 90 degree
elbows and never use a 180 degree elbow. Make sure that every suction coupling/connection is airtight. Always use a valve on the discharge of the pump.
In case of a fl ooded suction, in which the liquid level is higher than the center of the suction entrance, provide a T-connection with a small valve after the
discharge valve to assist in letting the air out during fl ooding. In case of a non-fl ooded suction, in which the liquid level is lower than the center of the suction
entrance, provide a foot valve on the end of the submerged suction line.

Section IV - Maintenance
Recommended Maintenance Schedule
The recommended maintenance schedule depends upon the
na-tureoftheuidbeingpumpedandthespecicapplication.
Ifthepumpisusedonacleanuid,itisrecommendedthatthe
pump be removed from service and examined after six months of
op-erationorafter2,000hoursofoperation.Ifthepumpisused
onuidswithsolids,hightemperatures,orinotherconditions
that could cause accelerated wear, then this initial examination
shouldbesooner.
Aftertheinitialexaminationoftheinternalcomponentsandwear
itemsaremeasured,aspecicmaintenanceschedulecanbe
determined.Forbestresults,itisrecommendedthatthepump
beremovedfromserviceannuallyforexamination.
Section V - Disassembly
WARNING:RotatingParts.Thispumphascomponentsthat
rotatewhileinoperation.Followlocalsafetystandardsforlocking
out the motor from the power supply during maintenance or
service.
WARNING:ChemicalHazard.Thispumpisusedfortransferring
manytypesofpotentiallydangerouschemicals.Alwayswear
