Five years ago, an engineered pump service center in the Midwest received a call from a large municipal sanitary district. One of the company’s four submersible pumps had tripped the overloads. This 890-rpm unit operated on variable frequency drives that adjusted the motor speed to match the fluid inflow.

When an East Coast nuclear plant wanted to increase the performance of its Layne & Bowler 25 RKCH two-stage vertical lineshaft, wet pit, service water pump, reverse engineering services to upgrade the repair of this unit was chosen. Driven by a 350-horsepower, 1,200 rpm vertical motor, this unit is approximately 45 feet in suspended length.

When a nuclear power plant pulled its vertical condensate pump for routine maintenance, an emergency situation was not expected. The plant pulled the pump and installed a replacement from storage, but it failed catastrophically after only two days in service. Requiring a solution for the emergency need, the plant accepted a workscope from a service center that promised a refurbished pump within nine days.

Analyzing the poor repairs on a boiler feed pump and how they affect the pump's performance and reliability. It is often said that a picture is worth a thousand words. This old adage could not have been truer when a coal-fired power station received pictures from the inspection team at a service center.

Typical vertical pump types include turbine, mixed and axial flow. The Hydraulic Institute classifies these pumps as type VS (Vertically Suspended). Unlike horizontal pumps, these pumps typically have the pumping element (impeller, diffuser, column pipe and pump shaft) submerged in the pumpage. Therefore, the metallurgy of all pump components must be compatible with the pumpage to achieve adequate life (MTBF).

Descaling is one of the more severe, but critical, services in a steel mill. The pressures are high and the rapid changes in flows and pressures severely impact the pumps. At the same time, the pumps' performance can significantly impact the quality of the steel produced.
