2/57

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.


3/57

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.

Pump Assembly Department

All pumps are assembled in house.

This allows March to customize our

pumps to suit your needs.


13/57

Plastic Molding

March has 6 injection-molding machines

which allows for March to produce

over 95% of our plastic parts in-house.

Machine Shop

Our machine shop provides March with the capability to make modifications

to any of our pumps to satisfy your pumping applications.


15/57

Finished Pumps

March has over 1,500 pumps in stock. With

this stock, March can ship pumps out faster

then any of its rivals.


16/57

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


53/57

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.


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.
