20 GPM Grundfos Pump With VFD MCU

GRUNDFOS PUMP SYSTEM:
LARGER FLOW CAPACITY– Grundfos vertical multistage centrifugal pump system has 20 GPM (5 HP) flow capacity.
LONGER LIFE/LESS MAINTENANCE– Stainless steel impellers, TEFC (totally enclosed fan-cooled) motors, & higher temperature thresholds for longer life/less maintenance. Systems are rebuildable for lower lifetime costs.
FULLY INTEGRATED SYSTEMS– Includes VFD motor, pressure transducer for pressure/flow control, inlet/outlet plumbing connections, wye strainer, & 8' power cord with flying leads.
VARIABLE FREQUENCY DRIVE (VFD):
EFFICIENT– Adjusts motor speed based on site demands & system flow requirements resulting in reduced energy consumption/costs.
EXTENDS LIFE OF PUMP– Less wear & tear on motor and cooler running pumps due to water not bypassing.
IMPROVED CHEMICAL CONSISTENCY– Tighter tolerances on VFDs eliminate pressure fluctuations that may vary by +/- 10-15 PSI on standard water pressure regulators. 
POTENTIAL LOCAL UTILITY REBATES– Contact local utilities or check the national database at dsireusa.org for energy saving rebates.
