20 GPM Grundfos Pump With VFD MCU

20 GPM Grundfos Pump With VFD MCU

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.
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.
