How do you grease a pump motor?

How often do you grease a pump motor?

When the operating temperature is between 80°C – 100°C (176°F – 212°F), oil should be replaced at least every three months. For critical equipment, it is advisable that lubricating oil be analyzed at least every three months to determine when oil replacement is necessary.

What kind of lubricant is used for electric motors?

A NLGI 2 grade grease is the most commonly used in electric motor applications. ASTM D 3336 oxidation life. require a grease with an EP additive. Dropping Point: The dropping point gives an indication of the temperature at which the grease will melt or the oil will separate from the thickener.

How do you lubricate a pump?

The most common types of methods for lubricating rolling element bearings in horizontal process pumps are:

  1. Grease.
  2. Oil Splash (Direct Contact, Rings, or Flingers)
  3. Pure oil mist.
  4. Purge oil mist.

What will happen if you do not grease or oil the pump and motor?

Answer: It will have catastrophic failure due to overheating.

Can you lubricate an electric motor?

Expert advice: When oiling an electric motor, be sure to use oil that’s specifically designed for motors. When oiling an electric motor be sure to use special oil for lubricating electric motors. Other oils could cause excess wear and premature failure.

What happens if you over grease an electric motor?

Over lubrication can cause the grease or oil to get into the windings. This will cause the insulation to deteriorate around the winding, resulting in arcing and shorting inside the motor to the case. Over lubricaiton will also cause excessive heat and wear on the rotor and stator.

Can you use wd40 on electric motors?

Yes, it can as WD 40 has oil base which can make winding insulation more weaker and can damage your motor. Also, WD 40 is not recommended to be used over electrical contacts.

Is Lithium grease good for electric motors?

The grease consistency preferred for electric motors is normally NLGI 2 or 3, with a base oil viscosity of 100-150 cSt @ 40°C. … A polyurea thickener system is preferred for most electric motor applications, but grease with an aluminum complex, lithium complex or calcium sulfonate thickener are also good options.

How do you clean electric motor windings?

Originally Answered: How do I wash the winding of an electric motor? Dip the winding in hot fresh water and let it stay there for ~ 20 min to loosen dirt & grease. Repeat if necessary. Air dry and if feasible oven dry thereafter.

How do you ensure the lubrication pump is effective?

It is important to start with the basics:

  1. Use the correct lubricant for the application.
  2. Viscosity.
  3. Mineral or synthetic.
  4. Understand how the pump is designed to properly lubricate the bearings.
  5. Oil splash, oil mist.
  6. Maintain the lubricant at the proper level.
  7. Constant level oilers.

Can I use hydraulic oil in a vacuum pump?

4 Can I use simple hydraulic oil for my rotary vacuum pump in place of rotary vacuum pump oil? Ans. No, you should never do that as this can seriously damage your rotary pump. … Unlike hydraulic oil, rotary vacuum pump oil has a low vapor pressure.

How do you lubricate a centrifugal pump?

The most common centrifugal-pump lubrication-application system is the oil bath fed by a bottle oiler. In some cases, depending on the amount of oil in the bearing housing, a slinger or flinger may be required to properly lubricate the bearing.

What is poor lubrication?

Many people hear “poor lubrication” and they immediate think this term refers to the quality of the lubricant itself, and it can. However, poor lubrication is really any aspect of a lubrication program not done with precision and includes: Incorrect amount of lubricant; too much or too little lubricant.

Can a bearing be over greased?


An abundance of grease in a bearing cavity will cause rotating bearing elements to begin churning and pushing the grease out of the way, resulting in energy loss and increased temperatures.
