gener al

Armstrong Centrifugal Pumps, properly installed and given rea-

sonable care and maintenance, will perform satisfactorily for a

long period of time. These instructions describe the procedures

which should be followed to ensure trouble-free operation. All

work should be performed by qualified personnel.

inspection

Armstrong series 4280 motor mounted pumps are thoroughly

tested and inspected before shipment to assure they meet with

your order requirements. All units must be carefully examined

upon arrival for possible damage during transit. Any evidence

of mishandling should be reported immediately to the carrier

and noted on the freight bill.

important

Do not run the pump for any length of time under very low flow

conditions or with the discharge valve closed. To do so could

cause the water in the casing to reach super heated steam

conditions and will cause premature failure and could cause se-

rious and dramatic damage to the pump and surrounding area.

1 location

Locate the unit as close as practical to the liquid being pumped,

with a short, direct suction pipe. Ensure adequate space is left

around the unit for operation, maintenance, service and inspec-

tion of parts.

Electric motor driven pumps should not be located in damp or

dusty location without special protection.

2 storage

Pumps not immediately placed into service, or removed from

service and stored, must be properly prepared to prevent rust-

ing and bearing damage.

Bearings are lubricated by grease, and must be rotated every

two to three months to return the lubricant to the upper half

of the bearing and prevent ball damage. Do not leave shaft in

same position each time.

Internal rusting can be prevented by removing the plugs at the

top and bottom of the casing and drain or air blow out all water

to prevent rust buildup or the possibility of freezing. Be sure to

reinstall the plugs when the unit is made operational. Rust

proofing or packing the casing with moisture absorbing mate-

rial and covering the flanges is acceptable. When returning to

service be sure to remove the drying agent from the pump.

3 foundation and mounting

The following text is offered as general suggestions for the

preparation of a satisfactory foundation.

Foundation should be sufficiently substantial to absorb any

vibration and permanently support the unit.

The most satisfactory foundations are made of reinforced con-

crete and should be at least 2.5 times the shipping weight of the

pumping unit. The foundation should be poured well in advance

of the installation to allow proper time for drying and curing.

Locate the pump on its foundation and mark off the foundation

holes, using the motor feet as the template. Drill (4) holes the

required size and insert anchors. Use only the motor feet to

secure the pump and motor unit. Do not use the pump casing

support feet. Use a tamping tool to drive home the lead sleeve,

until it is below the level of the foundation and firmly fixed into

the concrete.

Protruding bolts should be avoided, since this arrangement

would not allow disassembly, or back-pullout, of the unit with-

out disturbing pipe connections.
