I have been using a Comet pump for the last 12 years. It is still functioning like new. I only replace a diaphragm once in a while. I am buying another Comet this week.

Know where to fill oil on a p48?

[@pratimapawar6133]

There is lack of technical advisor to take proper maintenance of pump. Spare not getting easily. And it's to costly.

Comet is the best pump.

Hello Ralph. Great question, try Barsol or CLR. We have heard those work the best. Any other questions, let us know Ralph!

How can I remove the pump from the motor?

[@CometPumps]

Hello Carlos. The pump is secured by 4 bolts from the gearbox to the motor. Those 4 bolts need to be removed to disassemble the pump from the motor. If it still doesn’t come off the motors shaft it may take some prying but will need to be careful to not crack the housing. We have in the past also used a torch to heat up the female part of the shaft to get the pump to release. If you have any questions, please reach out to either our email: [e-mail] or toll free phone # [phone]

Type of oil for diaphragm pumps

[@CometPumps]

Hello, you would want to use 30w non detergent oil for a Comet diaphragm pump. Any other questions, please let us know!

Funny how the video skips the actual removal of the valve plug, which is an enormous pain in the ass on older pumps.
