I have seen a lot in my practice, I had to work with many equipment, but I did not encounter screw pumps. They are very expensive, including in maintenance, and, accordingly, are rare. And so it happened. The problem is immediately with two pumps Н1В 20/5 - 16/5 (N = 5.5 kW, n = 1440 rpm).

Посторонний шум, Вибродиагностика

One of the common reasons for calling a specialist in vibration diagnostics is noise from the unit. Sometimes the reasons are commonplace: a plastic bottle stuck between the fan blades (noise + vibration), lack of tightness of the door to the air conditioning fan chamber (whistling noise), faulty pressure valve in the ventilation network (periodic noise + vibration), etc. But more often, extraneous noise is a consequence of mechanical problems of the unit, which are the task of technical diagnostics to identify.
