Magnetic drive pumps, or mag-drive pumps, use a magnetic coupling to transfer power from the motor to the impeller, eliminating the need for traditional shaft seals and effectively preventing leaks. They operate with two sets of magnets: an outer magnet connected to the motor shaft and an inner magnet attached to the impeller. As the motor rotates, the outer magnet generates a magnetic field that induces rotation in the inner magnet, driving the impeller. A sealed containment shell separates the magnets, ensuring a leak-free operation, making these pumps ideal for handling hazardous or corrosive fluids.

March Pumps, known for their seal-less magnetic drive technology, are used in diverse applications, including harsh chemical transfer, heat transfer, industrial processes, medical systems, marine applications, solar systems, and food and beverage processing. March Pumps are great for harsh and corrosive fluid transfer.

March Pumps are highly regarded for their durability, reliability, and quality, particularly in applications involving corrosive chemicals or where seal leakage is a concern. Their magnetic drive design eliminates the need for traditional seals, reducing maintenance requirements and enhancing longevity. The company prioritizes quality control by performing much of its molding and machining in-house, allowing for precise manufacturing and customization. Constructed from durable materials, March Pumps are built to withstand demanding conditions while offering efficient, low-maintenance performance.

To properly set up a March pump, mount it horizontally on a stable foundation and secure it with anchor bolts, ensuring it's as close and low to the suction source as possible for a flooded suction. Use straight suction piping at least five times the pipe diameter before any elbow or valve, and avoid excessive bends or long piping runs to prevent cavitation. The suction piping should be at least the same size or one size larger than the pump’s inlet, and independently supported to avoid stressing the pump. Install a vacuum gauge near the suction port and ensure the available NPSH exceeds 120% of the required NPSH. Use a ball valve for maintenance (never to throttle flow), and avoid negative suction or suction lift. On the discharge side, use appropriately sized piping (max 15 ft/sec velocity), install a throttling valve for flow control, and add a discharge pressure gauge. Ensure correct motor rotation, prime the pump before starting, and never run it dry. Open the suction valve fully, crack the discharge valve, check for leaks, and then start the motor, slowly opening the discharge valve to the desired flow. Always maintain proper electrical supply and avoid operating at shutoff conditions for extended periods to prevent overheating.
