4.4.3.2 Delete this paragraph and replace with:

Pumps with three or more stages shall be disassembled after the performance test and

inspected, and all internal parts shall be coated with a suitable rust preventive before

reassembly. Single and two-stage pumps need not be disassembled after the performance

test, provided the pumps, including the stuffing box, is completely drained and dried and

all internal parts are coated with a suitable rust preventive. Vertical pumps that have

impellers mounted on the shaft with collets should not normally be disassembled after a

successful performance test. The pumps must be drained thoroughly after testing and

flushed with water containing less than 50ppm chlorides and drained again.

Where complete drainage is impossible, it is necessary to flush with chloride-free water,

alcohol, petroleum distillate or suitable flushing solution. Hot air drying is not acceptable

in lieu of flushing, but water can be blown out of pockets with compressed air.

4.4.3.13 Add the following paragraph:

Pumps with seals installed, drivers and all furnished auxiliaries shall be shipped fullyassembled on the baseplate, except as noted below. Coupling spacers with bolts, and

other items such as minimum flow orifices which are not part of the assembled pumping

unit, shall be separately boxed and tagged and securely attached to the baseplate.

(227 kg) may be removed after shop mounting and alignment and shipped

separately but alongside the pump;

- vertical pumps with suction tanks and vertical canned pumps shall be shipped

with the suction tanks (barrels) removed.
