A technology was introduced late last year to continuously monitor vibration levels of AC induction motor-pump machine trains along with automated analysis of each measurement. This technology provides operating personnel with frequent information for those situations when maintaining pump operation was critical to process integrity.
When stator wear was an issue, a custom-made replacement part was the solution.
The Jordan, Knauff & Company (JKC) pump and valve stock indices outperformed the broader S&P 500 Index. The JKC Valve Stock Index was up 37.9 percent over the last 12 months, above the broader S&P 500 Index, up 28.5 percent.
Computer-aided engineering enables the improvement of pump hydraulic performance in power plants.

With large-scale consolidations of OEMs in the pump industry and the closure of foundries in North America, advanced non-OEM pump rebuild shops have emerged that offer creative solutions, competitive pricing and quick turnaround time to pump users. A qualified independent rebuild shop employing highly experienced personnel and a range of advanced technologies can offer cost effective and creative solutions to long lead times on new pumps, which often range from 6 to 12 months.
The benefits of a new diaphragm pump
Pumps & Systems, February 2009
The operating costs of pumps, in relation to the service life, are considerably higher than the initial investment. Realizing savings on existing pumps means looking at operational efficiency and differential head. Mechanical retrofits are common in the market, but do we know enough about power retrofits to improve operations and save money on pumps?
