In some ways, pumps are very simple devices, which explains their regular and repeated use throughout history. In other ways, though, pumps can be extraordinarily complex. Affinity laws. Hydraulic gradients. Suction specific speed. Air entrainment. Cavitation. Those are only a few, randomly selected elements that you need to consider when selecting a pump and designing a system. And another element that you’ll need to think about is the relation between dynamic viscosity and specific gravity — particularly when installing a centrifugal pump.

Plastic resin is a major player in the raw-materials world. According to the American Chemistry Council, U.S. production of resin reached 7.7 billion pounds in October 2020, a year-over-year increase of 5.6 percent. Allied Market Research also noted that the sector makes a major global impact, reaching a value of $403.1 billion in 2019 that’s expected to grow to $522.5 billion in 2027. Resin is a major component in many types of products — including centrifugal sealless magnetic drive pumps.

In this post, we’ll explain what plastic resin is, how many types of plastic resins have industrial applications, the plastic resin types we use here at March Pump, and the various ways in which different resins can benefit end users.

There are a lot of pump selection criteria that go into maximizing centrifugal pump efficiency and ensuring that you have the proper setup for your site. The size of the pump itself. The sort of liquid you need to move. That liquid’s viscosity, acidity, and percentage of solids. The impeller dimensions and its type of connection to the pump. How far the material needs to move. Indeed, these are all important factors. But there’s something else you can’t forget: the piping itself.

Indeed, pipe can prove just as important as a pump itself — if not more so. Elements as seemingly innocuous as the angle of the pipe and even its diameter can mean the difference between the successful movement of liquid and an ignominious failure. This article will discuss pumps requirements for various kinds of applications, including how pipe length and diameter can come into play.

Believe it or not, the pump is a truly ancient piece of technology. Industry journal Pumps & Systems highlights how the first known pump originated in Egypt around 2,000 BC. Called the shadoof, it aided in irrigation by using a crane-like apparatus to move water. Pumps have advanced a lot since then, but their basics remain the same: Using some kind of mechanical action, they move liquids, gasses, and/or slurries from one place to another. Magnetic drive pumps — such as the kinds we craft here at March Pumps — are particularly interesting since they replace several standard pieces of pump equipment with a magnetic coupling. This leads to greater endurance and longevity. Read More about Common Causes for Magnetic Drive Centrifugal Pump Failure »

We use pumps every day. But do we know how pumps work? From watering our lawns and keeping our pools functional to cooling our homes and fueling our cars, pumps have countless common applications. But the specifics of their function escape most of us. And did you know that pumps feature heavily in industry — almost every industry in fact! Construction, manufacturing, medicine, agriculture, chemical production, and food service are just a few of the areas where pumps play an important role.

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 »

316 stainless steel is built to last—it can pump toxic and corrosive chemicals just as well as it can work with water and wort. 316 stainless steel is known for it for its strength and durability across a wide-range of chemical pumps.
