Startup Checklist for Vertical Turbine Well Pumps
Check for abrasive material (sand pumping) or the
presence of gas within the well.
Make immediate check of water level and record data
for future reference. Perform pumping and recovery
water-level checks as shown in Figure 6.
Check pump pressure and flow output. Determine the
corresponding pumping level in the well. Compute
the field head (1) and compare it to the pump curve
supplied by the manufacturer (2).
After pumping for 24 hours, collect a water sample for
microbiological analysis to ensure water is free from
(1) Field head is computed as follows: calculate the static and dynamic head losses
being overcome by the pump. The total field head equals (a) the friction losses
in the pump column and through the pump discharge elbow to the location of the
pressure gage on the pump plus (b) the vertical distance from the pumping level
in the well to the pressure gage plus (c) the pressure gage reading converted to
feet of head.
(2) The manufacturer's pump curve should be a combined curve showing a
composite assembly rating for multistage pumps, not a single-bowl-assembly
curve used for a single-stage pump.
For additional help reading pump curves or calculating head losses, consult par. 2.1.1.
A sample field head calculation is provided in Appendix A.
