All specifications & data are based on pumping water & are intended as a guideline only. Specifications may vary with different motors.
DESCRIPTION: Series 5 are centrifugal magnetic drive pumps, eliminating the need for a shaft
seal. All are serviceable with a screwdriver.
OPERATION: 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. 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.
ELECTRICAL: Models are dual voltage 115/230V for 60hz and 110/220V 50hz. The standard
motor has a conduit box. A motor with 115V 72 inch cord or 230V 72 inch cord, are options. The
motor is U.L. listed motor and rated for continuous duty. The pump is rated IP44. The pump is
Ignition Protected per SAE J1171 and ISO 8846.
CE: Pumps marked with CE have been modified to be listed as CE. Contact March for more
information.

Safety Instructions & Preventive Maintenance
Read this sheet and the appropriate pump instruction manual before installing and operating any
pump. Failure to follow safety instructions may result in injury or death.
Health Precautions
These pumps utilize magnets. Any individuals with pacemakers, implanted defibrillators,
electronic medical devices, metallic heart valves, or sickle cell anemia should consult a health
care professional before working with these pumps.
Motor may become hot, exercise caution before touching. Allow the motor to cool down for a
sufficient amount of time before attempting any maintenance or handling to prevent burns or
injuries. Install pump in a well-ventilated area to facilitate heat dissipation and reduce the risk of
overheating.
The motor has the potential to present an electrical hazard. Prior to any maintenance or handling,
ensure power to the motor is OFF. If there is uncertainty about the electrical safety of the motor,
consult with a qualified electrician before proceeding with any maintenance/repairs.
Pumps may be heavy, use caution when lifting and/or relocating a pump.
Unpacking
Unpack the pump and/or parts and check for signs of shipping damage. If damage is detected take
pictures and contact the carrier. Check that all ordered parts are included.
Remove all labels and stickers from all wet end part surfaces that come into contact with the liquid
(impeller, shaft, thrust washer, housing(s), etc…). Do not remove labels on the motor, and/or exterior
of the pump. Do not remove labels from the exterior of marine pumps.
For stainless steel pumps, the impeller, thrust washer, and shaft are packed separately.

Installation/Operation Precautions
Installation of Complete Pump
Pumps should be securely fastened. Install the motor per local and national electrical codes. Always
ground the pump motor. Only use the specified voltage listed on the nameplate, do not operate the
pump with a different voltage then specified on the motor nameplate. Do not exceed the service factor
of the motor. Do not cover the motor. Check all electrical connections with the wiring diagram found on
the motor.
Most March Pumps are not self-priming pumps. Liquid must flow naturally to the pump. Do not operate
the pump until liquid is inside of the pump. Never run the pump dry.
If the pump is in a hazardous environment, utilize an appropriate explosion-proof motor.
Do not submerge the pump unless it is a submersible pump.
For further instructions, see March General Installation Guide.
Operation
The pump has moving parts when in operation. Follow local safety standards for locking out the motor
during assembly or disassembly.
The pump may be used for transferring various chemicals. Always wear appropriate person protective
equipment (including protective eye care, gloves, clothing, etc.) and follow safety procedures during
operation of pump. Procedures should be in place for draining and decontamination of pump before
disassembling or inspecting the pump.
Do not operate with a closed suction or discharge valve. Do not start with a closed suction valve.
The wet end and/or motor may become hot during operation.
Always check with a March Manufacturing representative before pumping any liquid with solids.
Maintenance
March Manufacturing has not established a general preventive maintenance schedule for its line of
pumps, as each application presents its own specific conditions. The pump should be checked upon
installation, first use, and monitored for one week. If any abnormality is detected concerning vibration,
noise, electric current, flow or head rate, turn off the pump immediately and inspect individual parts.
The pump should be periodically inspected for wear on the impeller bushing. The frequency of the
inspection should be determined by the customer.
Follow motor lubricating oil instructions as found on motor label. (Not every motor requires lubrication)
Bolts may loosen after extended running. Tighten bolts if loose.
Remove excessive dust or particles from motor.
Do not clean exterior of pump or motor with any flammable solvents.

Assembly/Disassembly
Magnets
Magnets on specific models may be strong enough to pull the wet end and motor end quickly together
during assembly or disassembly.
WARNING: Do not put fingers between the two mating surfaces (between impeller magnet and/or
impeller vanes and the rear pump housing) during assembly or disassembly, especially for the 7.5, 8,
and 10 Series. Magnets may attract tools, use caution.
Assembly
Contact March Manufacturing for proper assembly procedure concerning drive magnet and motor
bracket.
Exercise caution in removing impellers on all models but especially on the 7.5, 8, and 10 Series due to
the strong magnetic forces between the impeller magnet and drive magnet. When handling impeller
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 to resist the magnetic attraction. Keep magnets away from
and free of any metal chips and particles.
Do not overtighten fasteners. Contact March Manufacturing for appropriate torque levels.
Care must be taken that the “O” Ring sits in the groove appropriately. Do not pinch or nick the O-Ring.
Before connecting power, rotate the motor fan to ensure there is no binding or rubbing of the drive
magnet against the rear housing.
Disassembly
Disconnect power from the pump and drain the pump.
See “Draining the Pump” section below.
After draining, separate front housing/cover from rear housing. Ensure that no liquid is remaining on
the parts.
Separate the parts. Exercise caution in removing impellers on all models -- but especially on the 7.5, 8,
and 10 Series -- due to the strong magnetic forces between the impeller magnet and drive magnet.
When handling impeller hold onto the outer diameter of the impeller vanes with both hands and extract
the impeller from the rear housing. Hold the impeller firmly to resist the magnetic attraction as you
remove the impeller. Keep magnets away from and free of any metal chips and particles.
If any part appears damaged or defective, take pictures and contact a March Distributor or March
Manufacturing.
Individual parts are listed on the appropriate pump manual.
Shut Down Procedure
1. Disconnect the power/turn off motor.
2. Carefully close the discharge valve.
3. Close suction valve.
*Caution must be exercised with automated valves.
