Ordered a centrifigal pump and put a vfd on it at customers request. They had a gasoline powered version but it was smokey and noisy inside the shop. We ordered same brand. Pump motor is rated at 11.6 amps with instruction to not restrict flow of water in or out. Pump pulls well over 14. We had to drop the freq to about 55 to prevent overload. Is it to much to ask that equipment perform as suggested?
