New Flomatic 100E VFD, 100ES VFD Pump Check Valves
Compatible With Variable-Frequency-Drive-Controlled Submersible Pumps
Flomatic Corporation is bringing a new 1-inch sized variable-frequency drive (VFD) special patented pump check valve to groundwater professionals. The Model 100E VFD and 100ES VFD are designed for use with VFD-controlled submersible pumps.
Standard check valves tend to “chatter” and make a lot of noise when a VFD goes to low flow conditions, causing annoyance, premature wear and eventual failure. The new valves are designed to minimize flow losses and hydraulic shocks in the pumping system.
