FEATURES

These pumps are of rugged and durable construction, designed for long lasting

continuous operation and their stainless steel bodies provide good anti corrosive

properties. The motor is provided with built in overload protection.

For your information the charts, on pages 9 and 10, show the flow rate for each

pump at various heads. (HEAD is the distance, or height, from the surface of the

water to the point of discharge)

These pumps are designed to pump water containing solids in suspension. That is -

with a maximum of 5% solid content, and a maximum 3mm solid dia.

They are NOT designed for pumping slurry, sludge, mud or heavily polluted water,

and should NOT be used for PERMANENT INSTALLATION in fish ponds or any water

containing chemicals or other acidic contaminants including salt water.

Whenever the pump is used to pump contaminated water, e.g. to drain fish ponds

etc., you must ALWAYS immerse the pump in clean water and run it for a few

minutes on completion, to ensure it is completely cleansed of all contaminants.

The maximum depth to which these pumps should be submerged is 5 Metres.

Automatic Pumps, i.e. those fitted with a Float Switch, denoted by an 'A' suffix to

their model number, are suitable for permanent or semi-permanent installations,

e.g. installations where it is necessary to maintain a water at a particular level.

As the water level rises, so will the float. At a certain point the switch will operate

and start the pump. As the water level falls, so will the float until the switch operates

again and stops the pump.

Float switches are adjusted at the factory to provide the correct ON-OFF switching

mode, i.e. cut out when the depth of water is 40mm and will cut in again when

the level reaches 300mm.

You can adjust the level at which the pump cuts out by sliding the float switch

cable through the clip attached to the main body. Shorten or lengthen it as the

case may be. The shorter it is, the earlier the pump will cut out, and the water

therefore will be deeper at this point. Similarly, it will cut in earlier and the water will

therefore be shallower when it does so.
