5. d suction consult Form No 221 Installing and Operating Webster C Series Centrifugal Pumps for other piping options The performance curves for Webster pumps are based on water The power required to drive the pump varies directly with the specific gravity of the fluid Multiply horsepower required for water by the specific gravity of the heavier fluid Likewise centrifugal pumps are generally not suited for viscous fluids Ten weight motor oil for example may reduce capacity as much as 15 and increase horsepower requirement by up to 30 If motor is 3 phase check rotation before installing the pump Correct rotation is clockwise when viewed from behind the motor looking toward the pump If rotation is incorrect reconnect leads as shown on the motor nameplate Running the pump with incorrect rotation for more than a brief period seconds not minutes will cause severe damage Grind marks on the side or back of the impeller are part of the dynamic balancing process They do not indicate a damaged impeller After maintenance before reassembly check the pump shaft threads for pits corrosion or signs of cross threading If the threads show damage replace the pump shaft When replacing the impeller or nose piece to properly seal the impeller body and maintain locking tension the impeller nose piece should seat against the impeller at 40 inch lbs of torque If not remove it and find out the cause Do not operate the pump until the pr
