A vacuum pump is a powerhouse machine that removes air, gases, moisture, and contaminants from a system to create a clean environment for refrigerants. These efficient and powerful machines need clean ...

Cummins’ 5.9L diesel engines have many wonderful traits, from the simplicity of their design to the durability and reliability of their internal components. However, the powerplants also have parts ...

Any time the internal piping or components of a refrigeration system are exposed to atmospheric air, they must be completely evacuated before refrigerant can be added into the system. Proper ...

The last time we had this 470-inch Mopar big block on the dyno, it made 751 hp with Trick Flow heads and a dry sump oiling system. The dry sump setup that we used for those tests worked great, but it ...

We may receive a commission on purchases made from links. HVAC professionals need a good vacuum pump to evacuate air, moisture, and contaminants from refrigerant lines before recharging older systems ...

It seems like creating a vacuum should be a pretty easy job, but it turns out that sucking all the air out of something is harder than it seems. A cheap vacuum pump will get you part of the way there, ...

Single-stage and multi-stage vacuum pumps have been around for quite some time, but some designers and engineers remain unsure about when to use one versus the other. For example, which pump is best ...

MEMS and motor control are two things we cover and small vacuum pumps are often controlled by micros so it made sense to talk with Dr. Wei Yang about Honeywell’s latest technology breakthrough, a tiny ...

Among these dry EDWARDS models are the oil-free EDP 80 - 400 vacuum pumps for the chemical industry. The design of this reliable series is based on non-contacting reverse claw technology. This ensures ...
