Progressive cavity pump panels provide the surface controls required to operate PC pumps safely and reliably. These pumps place unique demands on the control system, especially around torque management and restart protection. Control Innovations supplies PC pump panels in VFD, full‑voltage, and soft‑start configurations, all designed to protect the polished rod, extend pump life, and support oilfield operating requirements.
A progressive cavity pump panel provides controlled operation of PC pumps while preventing excessive torque on the polished rod. The panel manages starting, stopping, torque limiting, and restart timing to reduce mechanical stress and avoid costly rod failures.
Key Features
Control Innovations PC pump panels typically include:
- Torque‑limiting control to protect the polished rod
- Backspin timer to ensure the rod fully unwinds before restart
- Inputs for Presco switches, over‑pressure shutdown, and E‑stop circuits
- HAND / AUTO selector for Pump‑Off Controller (POC) operation
- Remote speed reference for VFD units (4–20 mA or 0–10 V)
- Optional analog output for current feedback to POC systems
- Built‑in line filtering, with enhanced filtering available
This provides a complete, field‑ready control solution for PC pump installations.
VFD‑Driven PC Pump Panels
VFD‑based PC pump panels offer:
- Torque limiting to prevent rod damage
- Ability to slow the pump to maintain safe torque levels
- Reduced inrush current during starting
- Remote speed control from a POC
- Current feedback output for monitoring
The VFD automatically trades off speed to keep torque within the preset safe limit.
Full‑Voltage PC Pump Panels
Full‑voltage PC pump panels provide:
- Direct‑online pump operation
- Standardized wiring and terminal numbering
- Compatibility with POC systems
- Optional current feedback device
These panels offer a simple, cost‑effective control method while still supporting shutdown and monitoring functions.
Soft‑Starter PC Pump Panels
Soft‑starter PC pump panels offer:
- Reduced‑current startup
- Controlled torque during initial wind‑up
- Faster response to over‑current or over‑torque conditions than basic overloads
- Compatibility with POC systems
This provides a balanced solution between full‑voltage and VFD‑driven control.
Available Options
Control Innovations offers a range of options for PC pump panels, including:
- Accessory power for chemical injection pumps
- GFI‑protected outputs for heat trace
- Site run and fault indication lamps
- Live Presco test logic
- Site stands or pedestal legs
- Dead‑front doors
- Harmonic filters to meet IEEE‑519 requirements
These options allow the panel to be tailored to site‑specific needs.
Customization
PC pump panels can be customized to match operational requirements, site standards, or integration needs. Whether the application requires torque‑limiting VFD control, full‑voltage operation, soft‑start capability, or additional field interfaces, Control Innovations can supply a complete package built for oilfield environments.
