When buying a vacuum pump for your factory, you should look for flow rate (CFM), vacuum strength and durability. The flow rate tells you how much air the pump can move. The vacuum strength tells you how much pressure the pump can handle and how deep a vacuum it can create. Durable vacuum pumps are made from tough materials that can handle your working conditions day in and day out.
What Are the Different Types of Vacuum Pumps?
The different types of vacuum pumps are rotary vane, articulated piston, screw, liquid ring and claw pumps.
- Rotary vane pumps use centrifugal force to push a set of sliding vanes out against the pump’s casing, which helps trap and move air through the chamber.
- Articulated piston pumps operate like a car engine, with the piston moving inside a cylinder and drawing air through an intake valve.
- Rotary screw pumps create compression with screws that turn in opposite directions to trap, compress and move air along.
- Liquid ring pumps rely on a spinning ring of liquid to create separate pockets that capture and move air.
- Claw vacuum pumps use turning rotors to create space for drawing air and reducing the space to compress the air.
How Many CFM Is a Good Industrial Vacuum Pump?
A good industrial vacuum pump has a flow rate that matches your factory’s unique requirements, which can range from just a few CFM to hundreds of CFM, depending on your operations. If you’re running multiple systems or larger equipment, you’ll want a higher CFM to keep up with demand. The key is to choose a pump that keeps your workflow steady without overworking the equipment or wasting energy. If you’re not sure what you need, it’s worth reaching out to a vacuum pump expert to talk through your setup.
Can CFM Be Too High or Too Low?
CFM can be too high or too low when the air flow doesn’t match your system’s needs. If it’s too low, your pumps might not be powerful enough to support your equipment. But if CFM is too high, you could end up wasting energy or putting too much strain on your system. The goal is to find a pump with just the right CFM for the job so everything runs smoothly.
