ABSTRACT
Next, we will examine the troubleshooting methods for the case of an external gear pump operating at 415 RPM (3.55:1 gearbox reduction from 1470 RPM motor speed), delivering 219 gpm of heavy oil (2500 SSU) in the blending plant. The pump operation was reported to be noisy, and the customer contacted the pump supplier, after a local environmental inspector reported his findings on noise levels as exceeding the allowable limit and in need of correction.
