Gorman-Rupp’s Pump Control Panels with VFDs

VFD Control Panels from Gorman-Rupp

During the past two decades, the wastewater industry has significantly increased the use of variable frequency drives (VFDs) due to their ability to enhance operational efficiency and flexibility. Gorman-Rupp’s VFD control panels are at the forefront of this trend, offering superior wastewater flow control compared to traditional constant-speed pumps in wastewater pumping stations.

Advantages of Gorman-Rupp’s VFD Control Panels:

VFDs help reduce energy consumption. They improve wastewater treatment plant processes. VFDs ensure that the pumping rate matches the inflow. Soft start and stop features extend the life of pumps, motors, valves, and couplings. VFDs reduce inrush current and voltage dips, minimizing stress on the system. They reduce the potential for water hammer, protecting the system from damage. VFDs provide the flexibility to change the pumping rate as needed.

Gorman-Rupp’s Pump Control Panels with VFDs:

These panels come in NEMA 3R steel enclosures with panel heaters and ventilation fans. They include a lockable main circuit breaker, Hand-Off-Auto selector switch, elapsed time meter, and a door-mounted keypad message center (HIM-Human Interface Module). The panels have a door-mounted disable push button and indicating lights for pump run, VFD fault, and no flow/load. They use Allen-Bradley Power Flex 753 variable frequency drives and are UL-listed. The panels allow for remote start/stop operation with panel connectors for inputs. They can be set up for two float inputs (start and stop levels at a preset speed) or a single transducer input (level and pressure). 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:

These panels are designed to precisely match controls to pumps and motors, ensuring optimal system performance. Customers choose from four liquid level control options when selecting a Gorman-Rupp ReliaSource solids-handling pump package. Gorman-Rupp control panels offer simple, reliable performance, with features for accurate start/stop operation, alternation, level sensors, pump delay, and alarms. Some panels include soft starters or variable frequency drives (VFDs) to manage electric inrush, hydraulic shock, and starting and stopping torque-based management and monitoring.
