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.

Pumps may be heavy, take caution when lifting and/or moving 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.

Page 2 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.

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.
Page 4 Troubleshooting General Notes • Liquids containing ferrous metal fines should not be pumped. • If magnets decouple, stop the pump. Running the pump with the magnets decoupled will weaken the magnets. Lack of Flow/Head • Check for air leaks in suction piping. •...
