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.
