WHY are in-tank vertical pumps the mainstream of wastewater pumps in the U.S.?
- Pumps at the wastewater treatment plants are of pivotal importance because any pump failure can cause inevitable downtime of the entire production line. Maintenance work cannot be easily performed due to the vastness of America.
Why are high-maintenance and costly vertical pumps so popular?
- Regardless of bearing wear, the greatest benefit of in-tank type vertical pumps is that the pumps never run dry, or will not stop immediately even when in erroneous operation. Furthermore, the timing of replacement of bearing is easily predictable because vibrations due to bearing wear and change in flow capacity that are the main causes of the pump failure gradually worsen.
