What size vacuum pump do I need?

We need to know, how big is your vacuum tank, what is the application--are you pumping septic tanks, food grease traps, car washes or skimming, are you working on flat ground or in mountains or hills, do you pull long distances and does your pump run 15-20 minutes or hours at a time? We size pumps to fit the application for free.

What is the best way to drive the pump 3 shaft right angle, belt & pulley, hydraulic or engine driven?

Depends on the space available, application and weather conditions you are working in.

I have a 2" primary and secondary shutoff can I use them with a pump having a 3" inlet and outlet?

No! It will not allow enough CFMs to pass through the new pump to keep it cool nor will the pump be able to produce the CFMs it was manufactured for, causing the pump to overheat and burn up. Everything needs to be sized for CFMs for a longer pump life. We size pumps and components for free.

Do I need a vacuum/pressure relief valve?

Yes the vacuum relief allows cool air to flow through the pump while under heavy vacuum adding longer life and better performance. Pressure relief keeps you from blowing up the tank and using excessive pressure on the system.

Should I use a final filter on my system?

Yes. While not absolutely necessary for the pump system, a final filter will catch the fine particulate that escapes the primary and secondary moisture traps. Therefore extending pump life while reducing vane wear. Moro USA, Inc. offers a wide variety of final filters, ask your sales representative for further details.
