The Design Envelope 4200 H split-coupled horizontal end suction pump is designed to adjust output to match the exact needs of an HVAC system in response to changes in system flow. Where many variable-speed pumps use a straight-line approach to speed control, the 4200 H adjusts and controls pump speed according to a quadratic curve that more closely matches the fluid-flow dynamics of an HVAC system. It also uses sensorless flow control for reduced installation costs and improved accuracy in speed control. Other 4200 H features include built-in harmonic mitigation, soft start and motor adaptation, and an outside mechanical seal and split-coupling design support easy maintenance.
