Gorman-Rupp Pumps Pumping Stations Control Panels Pennsylvania Maryland Delaware

VFD Control Panels from Gorman-Rupp

During the past 20 years, the wastewater industry has significantly increased the use of variable frequency drives (VFDs) in wastewater pumping systems. VFD control panels from Gorman-Rupp provide better wastewater flow control through pumping stations than constant-speed pumps. Plus, as power costs continue to increase and utilities look for ways to reduce costs, VFDs often provide a great solution.

VFD Advantages:

  • Power savings
  • Better for WWTP processes
  • Less likely to overload downstream sewer
  • The pumping rate matches the inflow
  • Soft start and soft stop feature extends the life of the equipment
  • Reduced inrush current and voltage dips
  • Easy on pumps, motors, valves, and couplings
  • Reduced water hammer potential
  • Provides flexibility to change pumping rate

Gorman-Rupp’s Pump Control Panels with VFDs are 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-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 and stop levels at a preset speed) or a single transducer input (level and pressure). The transducer input allows 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.

Lift Station VFD Control Panels from Gorman-Rupp

Gorman-Rupp’s lift station control panels are designed to ensure system performance by precisely matching the controls to the 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.
