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, a
spare parts stock is even more important to the user. Such spares
inventory may extend from a spare mechanical seal through com-
plete impeller-bearing 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 of the pump.
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.
