Learn Why Vertical Inline Is a Better Option than Base-Mounted, Centrifugal Pumps In years past, centrifugal pumps operated horizontally and were bolted to the floor. These base-mounted, pumps were a maintenance nightmare – requiring the removal of the motor to replace seals and perform other repairs. At 10 pounds per horsepower, motors in base-mounted pumps…

For both duty/standby and multi-pump applications, sensorless technology in Armstrong vertical inline (VIL) pumps offers superior control and maximum energy efficiency. Sensorless Overview Sensorless control enables a pump to decrease or increase its speed to match system requirements without any external signal. In other words, sensorless pumps emulate the performance of a remotely mounted sensor…
