Grundfos Pumps Corp.: Pumping System
Ideally suited for new commercial HVACR applications and retrofits, the fully integrated, intelligent LFE pumping system features the MLE variable-speed motor in 3-30 horsepower (hp) in 3,600 rpm and 3-25 hp in 1,800 rpm. The integrated, energy-optimized MLE system consists of a system controller, variable frequency drive (VFD), and standard asynchronous motor all-in-one and can be fitted with loose sensors. The LFE frame-mounted end-suction pump is available in 21 different models and features a compensated dual-volute design for reduced radial loads, minimized shaft deflection, and prolonged seal and bearing life. Its back-pullout design allows for ease of maintenance and servicing.
