Gorman-Rupp’s Pump Control Panels with VFDsJosh Price
During the past 20 years, the wastewater industry has seen a significant increase in the use of variable frequency drives (VFDs) in wastewater pumping systems. VFDs provide better control of the wastewater flow through pumping stations compared to using constant-speed pumps.
Gorman-Rupp’s Pump Control Panels with VFDs are offered as a standard product. Equipment is provided in NEMA 3R steel enclosures with panel heaters and ventilation fans. Panels to include lockable main circuit breaker, Hand-Off-Auto selector switch, elapsed time meter, door-mounted keypad message center (HIM-Human Interface Module), door-mounted disable push button, indicating lights for pump run, VFD fault, and no flow/load. The control panels come standard with Allen-Bradley Power Flex 753 variable frequency drives and are UL and cUL listed.
Panels include logic in the VFD for remote start/stop operation with panel connectors for inputs. The panels are set up for two float inputs (start level and stop level at a preset speed) or a single transducer input (level and pressure). The transducer input allows for variable speed pumping based on the scalable 4-20 mA signal. Dry contacts are provided for monitoring drive run, drive faulted, no flow/load, and torque/power out-of-range alarms. Control panels are available to ship from Gorman-Rupp in four weeks or less.
Gorman-Rupp’s lift station controls are designed to ensure system performance through precise matching of controls to pumps and motors. Customers have four choices in liquid level controls when they select a Gorman-Rupp ReliaSource solids-handling pump package. Gorman-Rupp control panels offer simple, reliable performance and are designed for accurate start/stop operation, alternation, level sensors, pump delay, and alarms. Advanced control systems include soft starters or variable frequency drives (VFDs) to manage electric inrush, hydraulic shock, and matching starting and stopping torque-based management and monitoring.
