Oil Filled Pumps – A Quick Analysis of its Pros and Cons

The debate between air filled and oil motors is an ongoing one! So, basically what is an oil filled motor and what is an air filled motor? An oil filled pump is defined as having the motor cavity filled with oil, usually to cover the upper bearing and windings. An air filled pump is one that does not use any oil to fill the motor cavity. Wondering whether you should consider oil or air filled pumps for your application? Well, talk to the experts in pump industry today to get reliable solutions for your pumping problems.

Oil filled motors lower the winding temperature through extra heat transfer away from the stator, to the housings, and then out into the liquid. Heat kills electrical components so anything that is done to lower the temperature inside the pump will give a long lasting product.

Other advantages of oil filled pumps include –

• Better lubrication of bearing
• Lesser frequency of maintenance
• Ensure long life of pumps
• Transfer heat easily
• Easy to maintain

The downsides to oil filling are the environmental consequences and a lower overall efficiency due to churning losses when compared to an air filled type motor. The environmental issue can be easily resolved by using a type of oil that is environmentally friendly. The lower efficiency carries about 2% increase in overall energy costs. Both of these penalties are pretty easy to offset when the pros of oil filling are explored.

Why Choose Darling Pumps?

• Darling pumps do not require any oil replacement since it never gets heated up beyond its limits.
• The pumps are generally designed for 360 volts to 440 volts Electric supply, which to certain extent negates the damage caused due to voltage fluctuation.
• Extra heavy duty Bearings does not require frequent maintenance.
• Our Oil filled design ensures proper lubrication to bearings even in case of continuous duty.
• As Darling Pumps are wound with PVC Insulated winding wire, in case of emergency the motor can easily rewound at site itself. You don't have to send it to factory for repairs.
