 New 702 Model Elevation Pumping Adjustments In cases of extremely shallow pump settings with extremely high elevations above surface, you may be able to increase cylinder size of pump. In cases of extremely deep submergence of pump below pumping level, you may need to decrease cylinder size of pump. Note: Adjustment to Pumping Elevation on Table of Pumping Capacities chart.  Overload! - When operating Under overload conditions, it may cause: fatigue and failure of Wheel Parts, excessive wear of Gears and Bearings and decrease the production and life of the windmill. For warranty considerations, Consider Operating Ranges. Sinker Bar: (use with rod strings that are non-ridged or that are lighter than 43lbs. Per 100 Ft.) The use of a steel shaft (1-3/16" Dia.), to tie sucker rod strings to the working check of the pump, may increase the pumping capacity up to 30% by keeping tension on the rod and helping insure full stroke of the pump. A sinker bar that has been precision machined will also help insure proper alignment of the working check (plunger) in the cylinder, thus increasing the efficiency and expected life of the pump. Calculation for Sinker Bar Sizing: 1lb. Per 23' of sucker rod (10 lbs. Minimum)  Pony Rod: Usually a short rod with precision aligned rod couplings used for alignment of the working check (plunger) in the cylinder, thus increasing the efficiency and expected life of the pump cups (leathers). |
