To select the appropriate March pump, begin by evaluating the liquid’s characteristics, such as viscosity, corrosiveness, and temperature. Next, determine the flow rate and pressure requirements of your application. Make sure the available NPSHA (Net Positive Suction Head Available) is greater than or equal to the NPSHR (Net Positive Suction Head Required) to avoid cavitation. Lastly, choose a pump material that is compatible with both the liquid and the operating pressure.
When choosing March pumps consider these main factors in order to find the right pump for each application.
March pumps come in a variety of materials. This allows them to be used with a variety of fluids. Ensure the correct material is being used for the fluid being pumped.
Consider the viscosity of fluids being pumped. Different viscosities create different resistances which can affect the pressure and flow rate. Make sure the pump being used is able to accommodate for these affects.
Calculate the total pressure needed to propel the liquid through the application, and ensure the pump being used has sufficient power.
Calculate the maximum working temperature and choose a pump wit a material that can withstand that heat or cold.
Calculate the volume of fluid needed to be to pumped per minute or hour to find the flow rate. Ensure the pump being used can provide this flow rate.
Make sure there is more NPSHA (available suction pressure) than NPSHR (required suction pressure) to avoid the formation of gas bubbles in the application.
Use these additional factors to ensure the March pump being used is the optimal choice for the application.
Determine if centrifugal and magnetic drive pumps are right for the application. Centrifugal pumps are ideal for fluid transfer and magnetic drives are ideal for high temps and corrosive fluids.
Take into consideration pumps require maintenance and parts replaced. Some models require less maintenance and replacement parts than others.
The length and diameter of the piping application can impact the flow rate and pressure. Ensure the pump being used can account for these affects.
March manufactures pumps with varies power requirements. Ensure the pump's power requirements are the correct ones for your application and power supply.

Centrifugal pumps are pumps that convert rotating momentum into kinetic energy in order to propel liquids. They use rotating impellers to make centrifugal momentum that force liquids through the pump to the discharge pipe.
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.
