Single Stage Pumps in San Jose, CA

A single-stage pump uses one impeller that rotates on one shaft in a pump casing. The single-stage pump is meant to produce a consistent flow of fluid through the use of a motor. The only moving part of a single-stage pump is the piston, which moves up and down in the cylinder. As it reaches the top of the cylinder, the pressure created pushes the fluid out of the cylinder. These are the simplest types of pumps, and are very efficient and reliable, but aren’t as powerful as two-stage pumps. If you’re curious about the benefits and industry applications of single-stage vacuum pumps in San Jose, CA, contact us today at D & D Compressor.

Single Stage Water Ring Vacuum Pumps

There are many reasons why single-stage water ring vacuum pumps in San Jose, CA are the most popular and widely used. A single-stage water ring vacuum pump also called a single-stage liquid ring vacuum pump, produces a vacuum using a multi-blade propeller on a shaft that, as it turns, creates a liquid ring due to the centrifugal force generated by the rotating impeller. Because of the force created, the liquid ring is held against the pumping chamber’s inner wall. The depth of the blades’ entry into the liquid ring decreases and increases due to the rotation of the impeller, creating an increasing volume on the inlet port side and resulting in a vacuum. The popularity of single-stage water ring vacuum pumps is because they are simple and sturdy, and can run 24/7 for years without requiring maintenance or repair.




When to Use a Single Stage Pump

Purchasing a single-stage pump is often less expensive than purchasing a two-stage pump; however, a two-stage pump is more efficient and powerful. Single-stage pumps are recommended for use in low-pressure applications that don’t require the use of much fluid. Single-stage pumps are less expensive to operate, and when used correctly, can often last for years without maintenance. They are recommended for use with fluids with a low viscosity level. They are also typically much smaller in size than two-stage pumps, so they have a lower profile.
