1. Installation

warning:

Whenever any service work is to be performed on

a pumping unit, disconnect the power source to the

driver, lock it off and tag with the reason. Any pos-

sibility of the unit starting while being serviced must

be eliminated.

• If mechanical seal environmental accessories are

installed, ensure water is flowing through the sight

flow indicator and that filter cartridges are replaced as

recommended. (See Armstrong files 43 . 85 & 43 . 86 for

seal environmental instructions).

caution:

Under no circumstances should the pump be used

for flushing out the system. In line with cibse

commissioning code W: 1994, the pump should be

out of line or bypassed during flushing.

lubrication

Pump

Not required – there are no bearings in the pump.

Motor

• Follow the lubrication procedures recommended by the

motor manufacturer. Many small and medium sized

motors are permanently lubricated and need no added

lubrication. Generally if there are grease fittings evident

the motor needs periodic lubrication. None if not.

• Check the lubrication instructions supplied with the mo-

tor for the particular frame size indicated on the motor

nameplate.

Mechanical Seal

• Mechanical seals require no special attention. If leakage

occurs investigate the cause and replace the seal

following the makers recommendations, then realign the

pump and motor shafts.

• Do not run the pump unless properly filled with water as

the mechanical seals need a film of liquid between the

faces for proper operation.

• Mechanical seals may 'weep' slightly at start-up. Allow

the pump to continue operating for several hours and

the mechanical seal to 'seat' properly prior to calling for

service personnel.

caution

Do not use oil, Vaseline or other petroleum or silicon

based products for seal elastomer lubrication.

Series 4280

motor mounted pump

Otherwise elastomer swelling may occur, causing seal failure.

caution

The permissible tds levels are :

a SSiC Vs C – 2000ppm max

b SSiC Vs SSiC – 40 0 0ppm max

In case the water exceeds permissible tds levels, corrosion

or fouling may occur resulting in seal failures. It is necessary

to maintain the water quality with proper water treatment

program.

system cleanliness

• Before starting the pump the system must be thoroughly

cleaned, flushed and drained and replenished with clean

liquid.

• Welding slag and other foreign materials, Stop Leak and

cleaning compounds and improper or excessive water

treatment are all detrimental to the pump internals and

sealing arrangement.

• Proper operation cannot be guaranteed if the above

conditions are not adhered to.

caution:

Under no circumstances should the pump be used for flushing

out the system. In line with cibse commissioning code W:

1994, the pump should be out of line or bypassed during

flushing.

note:

Particular care must be taken to check the following

before the pump is put into operation:

Pump primed?

Rotation OK?

Lubrication OK?

Pipework properly supported?

Voltage supply OK?

Overload protection OK?

Is the system clean?

Is the area around the pump clean?

warr anty

Does not cover any damages to the equipment resulting from

failure to observe the above precautions. Refer to Armstrong
