Affinity laws in mag drive operation are used to “express the relationship between variables involved in pump or fan performance such as head, flow rate,” etc. These laws help mag drive pump operators to more closely predict the head discharge when delivered at different speeds or from different sized impellers.

One of the keys to consistent pump performance is discovering when your pump is operating at peak efficiency.
The best way to determine this is by identifying your pump’s BEP, or Best Efficiency Point. The BEP is a measure that shows where the pump is performing most effectively and is least likely to fail. A pump should operate at or near the best efficiency point. This should be provided by your pump manufacturer (our efficiency curves are listed on our website).

When selecting the appropriate motor for your industrial needs, it is of utmost important that the motor you choose suits the environment and working conditions of your facility. The motor you select must protect your assets and staff from explosion or intrusion into the body. It must also be able to perform its duties consistently and efficiently, while still fitting within your budget. Read More about How to Locate a Pump Motor IP Rating & Explosion Proof Rating »
A pump manual is essential reading for any industrial pump system operator. However, these manuals are thorough and complicated, so let us show you how to interpret the information listed and use it to optimize your industrial pump’s performance. We will be using our 8 Series Centrifugal Magnetic Drive Pumps as an example. Read More about How To Read a Pump Manual »
Valves on a pump control the flow of liquid through a pump. These help to regulate pressure within a pump and prevent against possible breakage. Any pump should have two valves attached; one at the inlet, or suction, and the other at the outlet, or discharge area. Read More about Where to Put a Valve on the Pump »
Priming industrial pumps is essential to using your pump for its intended applications and to maintain the equipment. Priming is the process of removing air from the pump and suction line to permit atmospheric pressure and flooding pressure to cause liquid to flow into the pump. Without priming, pumps will cease to function and break down.
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.
