The Taco SelfSensing Series with ProBalance integrates KV or KS pumps with a variable frequency drive. SelfSensing with ProBalance pumps allow the installer to accomplish easy, do-it-yourself system balancing for both constant-flow central plant applications and variable-flow building distribution applications. The system greatly reduces balancing contractor costs at commissioning or start-up, said the company. Pump performance curves are embedded in the memory of the speed controller. During operation, pump power and speed are monitored, enabling the controller to establish the hydraulic performance and position in the pumps head-flow characteristic, enabling the pump to continuously identify re-quired head and flow at any point, providing accurate pressure control without the need for external sensor feedback. The pumps can be run in constant-flow mode for chiller/boiler pumps (primary), system-curve mode for variable-flow pumps (secondary), and constant-pressure mode for booster pumps. The pumps include automatic alerts (with optional shutdown) for no-flow, dry-run, and end-of-curve operation, and are electronically protected for overload and locked rotor conditions.
