Adjust the throttle valve (near #4) to allow more delivery from #5 &6, if #4 is run along with either of #5 &6 is running. Details of Formation Water (F.W.) Pumps : There are four F.W. pumps, of which, one was found in out of order situation. Two pumps run at a time. The details of F.W. pumps are given : Formation Water Pump with Motor : Pump : Multi (7)-stages pump, total head- 200 mtrs, Capacity -25 m3/Hr., Efficiency -58%, KW, RPM-2940, NPSH required 1.6 mtr, Bare shaft- 166 Kg, make-Kirlosker Brothers – Electric Motor (Drive) : 3 Ph, 50 Hz, 30 KW, 2955 RPM, Efficiency -91%, make-KEC Measured Parameters of F.W.
