PUMP START UP CHECK LIST
To avoid prolonged down time and facilitate rapid repair of dam-
aged pump parts, Dean recommends that the pump user maintain a
minimum stock of spare parts. If the pump service is critical or the
pump parts are of special materials, spare parts stock is even more
important to the user. Such spares inventory may extend from a
spare mechanical seal or seal parts through complete casing back-
cover-impeller-bear ing housing assemblies prepared for immediate
insertion in the pump casing. Consult your Dean representative who
will assist you in selecting your spares stock.
ORDERING SPARE PARTS
Spare part orders will be handled with a minimum delay if
the following information is furnished by the customer with the
order:
1) Give the pump serial number and size. These may be
found on the pump name plate. The serial number is also
stamped on the suction flange or the top edge of the bear-
ing housing front flange.
2) Give the part name, part number, and material of part.
These should agree with the standard parts list.
3) Give the quantity of each part required.
4) Give complete shipping instructions.
SPARE PARTS
These points must be checked after pump installation and before
starting up the pump.
1) Read instruction manual thoroughly and understand it.
2) Review pump order head sheet for the service rating of the
pump and any special features.
3) Check all piping connections making certain that they are both
tight and in the proper places. All piping includes seal, cooling,
or heating piping.
4) Make sure that the baseplate has been properly installed.
5) Check the electrical or steam line connections to the driver.
6) Break the coupling by removing the coupling spacer assembly
and bump the motor starting button to check motor rotation.
Operating the pump in reverse rotation may cause extensive
damage. If driver rotation is correct, replace the coupling spac-
er. If not, connect the wiring for proper rotation and recheck.
7) Check coupling for proper alignment. Realign if neces sary.
8) If pump seal chamber is packed, check to be sure that
gland stud nuts are pulled up only finger tight and that the
gland is not cocked.
9) Rotate the pump shaft by hand to be sure there is no
binding or rubbing within the pump or driver. Correct any
difficulties at once.
10) Check to see that the pump is properly lubricated.
11) Remove all dirt, waste, tools, and construction debris from
the area.
12) Check to see that the coupling guard is securely in place.
