This maintenance bulletin deals exclusively with the bracket

mounted, Heavy-Duty, Stainless Steel Pumps. This type

of pump may be equipped with either a Multi-Ring stuffing

box with packing, called a Series 724 pump; or a Roto-Ring

mechanical seal, called a Series 4724 pump. The figure

number and letter prefix, which indicates the basic pump size,

make up the pump model.Both the packed and mechanical

seal pumps are similar in overall appearance to the pump

illustrated in

figure 1.

The pump or unit model and serial number which can be

found on a nameplate attached to the pump or base, are

important means of identification when ordering repair parts

or a replacement pump.
An outstanding feature of these pumps is the integral thrust

bearing which is easily adjusted and holds the rotor in a fixed

position. This bearing is a double row angular contact ball

bearing securely locked against a shoulder on the shaft by a

locknut. Adjustment of the thrust bearing, to properly position

the rotor, will be explained at the end of this article.

suction or discharge lines or other

appropriate openings or connections.

2. That the driving means (motor,

turbine, engine, etc.) has been “locked

out” or made non-operational so that

it cannot be started while work is

being done on pump.

3. That you know what liquid the

pump has been handling and the

precautions necessary to safely

handle the liquid. Obtain a material

safety data sheet (MSDS) for the

liquid to be sure these precautions

are understood.
