Dry running is as exactly as it sounds, running the pump without liquid. Pumps should not be operated running dry.
When a pump is run dry, there are two common results.
Check out the latest pump, TE-4MSR-MD, a 4 Stage Pump, constructed from Ryton, with a max head of 120 Feet.
We are often asked by our customers how to wire a TEFC (totally enclosed fan cooled motor) on a March Pump. These motors are one of the common motors used in industrial environments, and require training to maintain the equipment properly. We recommend to our clients that they refer to the March Motor Wiring Diagram. This is a highly organized and thoroughly detailed resource that can guide you through the wiring process. Here is our recommendation for the best use of the diagram: Read More about How to Read the Motor Wiring Diagram from March Pump »
There are multiple ways to select an industrial pump and multiple styles of centrifugal pumps to choose from. The primary selection tool is called a pump curve. Being able to read and understand a pump curve is frankly an essential skill if you’re someone who needs to select a pump for a specific application and you want to ensure that that your pump enjoys a long service life operating at maximal efficiency.

Owing to their well-earned reputations for consistent performance, sealless magnetic drive pumps are increasingly being employed in chemical process applications. Given their characteristics, magnetic drive pumps have made steady inroads into industries traditionally served by conventional mechanical seal pumps. Both the Chemical and Pharmaceutical industries are increasingly using plastic-lined sealless magnetic drive pumps to pump highly toxic and corrosive substances. And whether it’s a centrifugal pump or a self-priming pump, generally speaking a chemical pump that’s suitable for pumping corrosive liquids is subject to strict standards when in terms of safety, atmospheric leaks and of course, service life. These high requirements are the reasons for the trend towards sealless in particularly, magnetic drive pumps.
March Manufacturing is proud to have come out with a new front housing for the 809, 809-HS, 815, and Beer Pump Families. It is a stainless steel inline housing. It is 304 stainless steel. The inlet is half inch male pipe thread and the outlet is half inch male pipe thread. A pump with this housing can handle a maximum internal pressure of 150PSI. The maximum temperature is 250F (121C), but should an application arise where the temperature will exceed this number, it is possible to modify the pump to handle a greater temperature. The 304 Stainless Steel material is FDA compliant. The stainless steel front housing is preferred over a plastic housing because it significantly reduces the chance of cross threading (damaging the threads) when connecting the pump to stainless steel pipe.

So what exactly are sealless pumps? What are the specific feature and performance characteristics that substantively differentiate a sealless mag drive pump from a good old fashioned mechanical seal pump? For those of you who don’t already know the answers to those two questions, we’ve decided to devote this latest March blog post to explaining the ins and outs of a mag drive pumps advanced fluid handling technology as it were.
There are times when two dimensional drawings are not enough, and March Manufacturing understands that. Accordingly, March Manufacturing has finished drawing two of its centrifugal magnetic drive pumps in 3D. These pumps are the LC-3CP-MD and the 320-CP-MD. These 3D drawings are available in DWG, IPT, and STEP Format. March will continue to draw more of its models in 3D in time, but if you have a specific model you are interested in getting a 3D drawing of, please email Otto Zimmermann at email@example.com

If you’re going to brew beer at home, you’re going to need to transfer large volumes of liquid. That means a good pump is likely to become your new best friend. That’s right; you’ll need a pump and probably a centrifugal pump to homebrew all grain. A good pump can make transferring hot wort and boiling water easy. But what exactly is a centrifugal pump, what makes one good and why do you need one? Well, centrifugal pumps are actually a lot like household fans: Fluids enter through one port of the pump’s chamber, are whizzed around by a rotating impeller then pushed out the exit port at a higher pressure.

The building services industry has emerged as perhaps the primary driver of not only the economies of several European countries, but of the market for commercial and industrial pumps continent wide. This has been especially true for centrifugal pump manufacturers. You see; the major applications for centrifugal pumps within commercial and industrial buildings tend to involve fire protection systems, pressure boosting, heating, ventilation, air-conditioning (HVAC), drainage and sewage.
But the market’s recovery has been a long and often winding road. The global economic recession hit the building services industry across Europe hard and especially hard in countries such as Greece, Italy and Spain. As a direct result of the 2008-09 collapse, revenue generated from new pump installations across the continent fell by roughly $11.5 million. In 2010 we did see a period of more or less steady building services sector growth primarily fueled by the refurbishment market in Scandinavia and Germany. However, the sustained debt crisis of 2011-12 led to a second slowdown in new building activity as the industry suffered under the weight of the austerity measures imposed by several European governments.
