In its various incarnations, stainless steel often seems like an industrial standard for pumps and various other applications. The exact grade of stainless steel may vary, and end users may find themselves combining it with various polymers and other exotic materials, but stainless steel is the standard — right? Well, not exactly. For many applications, ceramic makes much more sense. Why? There are multiple reasons.

Steel isn’t ever just steel. Because it’s an alloy, different types of metallic compositions can lead to different types of steel. However, the most common type is 304 stainless steel.
Containing approximately 18% to 20% chromium and 8% to 10.5% nickel, 304 stainless steel offers all of the attributes you’d expect. Ease of fabrication. A wide variety of electrical, chemical storage, furnishing, and piping applications (just to name a few). Read More about Advantages of 316 Stainless Steel over 304 Stainless Steel »
The dictionary definition of a pump makes it sound like a relatively simple instrument. For instance, Merriam-Webster states that a pump is “a device that raises, transfers, deliver, or compresses fluids or that attenuates gases especially by suction or pressure or both.” But dealing with industrial pump applications where the materials involved can be exotic or hazardous leads to numerous complications, complications where technical expertise becomes paramount.

What is a multistage pump?
Multistage pumps are centrifugal pumps in which the fluid flows through several impellers fitted in series. This is as opposed to a single stage pump which only has one impeller. The more stages the pump has, the higher the final discharge pressure.
Multistage chemical pumps are unique in that they are able to produce increasingly higher pressures with the addition of every stage while the flow range always remains constant for a given rpm. Read More about Multistage Chemical Pumps 101 »
