SFI self-sensing, variable-speed end-suction pumps from Taco, with integrated VFDs, permit fast, accurate balancing. They help to reduce balancing contractor costs, eliminate expensive wiring and the need for external sensors. They meet the latest standards for hydraulic performance and dimensional characteristics for quiet, dependable performance. Their SelfSensing bypass option is an advantage for engineers who seek to bypass the variable-speed control. Customers can order either a NEMA 1 drive with an ODP motor or a NEMA 12 drive with a TEFC motor. An easy-to-replace, slip-on shaft sleeve facilitates easy field maintenance. Their dry shaft design protects the pump shaft by eliminating contact between the shaft and the circulating fluid. Flush-seal line taps allow installation of a filter to protect the seal from noncondensable particles in the system. Pressure tappings on the suction and discharge connections are standard. 401/942-8000; www.taco-hvac.com.
