Centrifugal Pump controllers

Ktech Industrial Products Inc.’s new Pump controllers automatically operate a pump to control the level of a liquid in a tank. Pump controllers are used in conjunction with Ktech Multi-level float switches. Two contacts are used to start and stop the pump. A relay circuit switches power to the fractional horsepower pump motor or to the three-phase contactor of a large pump motor. Similarly, the switch contacts can be used to operate solenoid valves. Additional contacts are used to indicate an alarm condition. Read the rest of this entry »

Centrifugal Pump Alignment

Proper alignment of the pump shaft with the driver can reduce vibration and significantly improve reliability. For appropriate applications, the time, expertise and instruments needed to achieve precision alignment (tolerances of less than 0.005 in) will prevent seal leakage and extend bearing life. Depending on such factors as operating speed and coupling type, not all pumps will require such precise alignment. When assessing a plant’s alignment needs, it helps to understand basic shaft alignment concepts and procedures, as well as application-specific factors that dictate the required tolerances.

Three phase Pump Control Panel

NEMA vs. IEC

There are two commonly used component standards for pump control panels – NEMA (National Electrical Manufacturers Association) and IEC (International Electro-technical Commission). What commonly are called IEC panels in this country actually are UL panels using IEC-style components. For discussion purposes, we will refer to them as IEC panels.
