Drive Pipe Construction
Two types of drive pipes are described.
Type A is intended for higher outlet heads. It consists of a 6.5 metres length of 25 mm (1 inch) galvanized steel pipe, reducing to 3.25 metres of 20 mm (3/4 inch) galvanized steel pipe, which is then connected to the complete pump assembly.
Type B may be better for lower outlet heads, around 10 to 15 metres or less. It uses the same pipes and fittings, but with the Outlet Valve at the join of the two pipes and the Main Pump Body at the end of the 20 mm pipe.
Overall views of the two types are shown in Photographs 3 and 6.
For most applications, it is suggested Type A be tried first.
Assembly of Drive Pipes
A 1 inch galvanized bend should be placed between the two lengths of galvanized pipe, so that they are at right angles to each other.
This improves pump operation, and also makes it easier to restrain the pump and keep the Main Pump Body upright.
An extra galvanized pipe bend and short pipe can also be placed at the end of the 3/4 inch pipe if this further helps to restrain the pump.
