On March 1, 1954, March
Manufacturing was launched,specializing in precision parts for the
aircraft industry.
During the late Fifties, March turnedtheir attention to the development of
pumps that featured the magnetic drivedesign principle.

In 1963 March patented themagnetically coupled drive pump
design. It eliminated shaft seals and the
many problems they cause.
Torque is transmitted by a magneticfield from the magnet attached to thepumps motor, through the solid body,
to the magnet attached to the impeller.

Our Pumps
All pumps are grouped in series. Our mainline of magnetic drive pumps range from the 1 series to 10 series.
The smallest standard pump (in terms of both physical size and gpm) is the 1 series.
The largest standard pump is the 10 series. The larger the number, the more gallons per minute they are capable of.
There are other series of pumps which March offers as well. There are the 893, 325, 335, 140, dual-headed, and MDX which are
standard magnetic drive pumps but differ in respect to power current, slightly different curves, or are targeted for special
applications..
The Hydronic Series is composed of magnetic drive pumps designed for hot water/solar applications. The Hydronic Series has 6
different pump series in it, the most notable being the 809-HS.
The defining characteristic of the remaining series is they do not incorporate the magnetic drive principle. These series are
metering, condensate ,and submersible seal-type pumps.

This is the first page of the chemical guide. If you cannot find the chemical youre pumping, do not hesitate to contact the
engineering department.

Impeller Trim Chart
For Specific Gravity
Liquids which are heavier then water require the impeller to be trimmed to prevent decoupling or overloading the motor. If
you know the specific gravity but cant determine the proper trim, contact engineering.
Bushings

54/57
Bushings
From left to right, Carbon, Mica-Teflon, Ryton-Teflon-Carbon, and Ceramic.
When selecting a pump with a bushing, be careful to check the chemical
compatibility of the bushing concerning the liquid being pumped.

8/13/2019 March Manufacturing: Industrial Pumps Guide
55/57
Pump Selection
Follow these guideline to select the proper pump1. How many gallons per minute are needed?
2. What head/pressure is needed?
3. What hertz is the pump to be run on (50 or 60 hertz)?
4. Visit www.marchpump.com, select the pump series with the curve that is nearest to your operatingpoint. All pumps have curves in both 50 and 60 hertz listed on the website.
5. Check the chemical compatibility of the liquid against the March chemical resistance guide. Most
series have different plastics/metals available, on the bottom of the individual series on the websiteis listed all the different options available. Once you know what plastics/metals are suitable andavailable in the series, scroll thru the page to find which particular model in the series is the correctone.
6. What is the chemicals viscosity and specific gravity? For liquids with high viscosity or specificgravities, please contact engineering to determine the best trim size. Note that all suggested trimsare meant for 60 hertz. If running at 50 hertz, the impeller may not have to be trimmed to such anextent. Please contact engineering when running at 50 hertz and the liquid is heavy.
7. Piping: Inlet pipe size should always be larger then discharge pipe size. As a general rule, never installa pump whose inlet is larger then the pipe size on the suction side.

Practice Problem
Using the information provided on the last few slides, answer the following applicationquestions:
1. Should the 7R or 7K be used when pumping Acetone?
2. What bushings and O-rings are compatible with Acetone?
3. Assume Acetone has a specific gravity of 1.5. Should the impeller be trimmed,
and if so, to what trim size? (assume you are operating with 60 hertz)
A

57/57
Answers
1. 7R. Ryton is rated A for Acetone, Kynar is rated C.
2. Teflon is the only acceptable O-ring. All the bushings are rated excellent.
3. If Acetone did have a specific gravity of 1.5, the impeller will have to be
trimmed to 3.5 inches in diameter.
