6.1.1 Condition of the well
If the pump is to be installed in a new well, make sure that the well
is fully developed and bailed or blown free of cuttings, drillings and
sand. The stainless steel construction makes the pump resistant to
abrasion. However; constant exposure to sandy water may cause
damage to the pump.
If this pump is used to replace an oil-filled submersible or oil-
lubricated line-shaft turbine pump in an existing well, the well must
be blown or bailed clear of oil.
Determine the maximum depth of the well, and the draw-down level
at the maximum capacity of the pump. Use this data for pump
selection and to determine installation depth.
Check the inside diameter of the well casing to ensure that it is
larger than the size of the pump and motor.
