VFD pump jack control panels provide a complete surface‑mounted control solution for beam pumps used in oilfield production. These panels use a standardized layout that supports a wide range of VFD manufacturers, allowing consistent operation and wiring practices across different sites and equipment. Control Innovations supplies pump jack panels designed for dependable outdoor service and seamless integration with Pump‑Off Controllers (POCs).
A VFD pump jack control panel provides variable‑speed operation, shutdown protection, and energy‑handling capability for pump jack systems. The panel manages start/stop control, torque and speed regulation, and safe operation during both upstroke and downstroke cycles.
Key Features
Control Innovations VFD pump jack panels typically include:
- Standardized layout compatible with multiple VFD brands
- Inputs for Presco switches, over‑pressure shutdown, and E‑stop circuits
- HAND / AUTO selector for POC integration
- Remote speed reference (4–20 mA or 0–10 V) for POC control
- Optional analog output for current feedback to POC systems
- Built‑in line filtering, with enhanced filtering available
- NEMA 3R outdoor rating for –40 °C to +45 °C operation
This provides a consistent, field‑ready control solution for pump jack installations.
Energy Handling During Overhaul
Pump jacks generate excess energy while lowering the rod string. Control Innovations offers three methods to manage this energy safely:
- Dynamic braking resistor
- Overspeed control during overhaul
- Active front‑end regeneration
These options allow the system to be configured based on site preference and operational requirements.
Full‑Voltage & Soft‑Start Pump Jack Panels
In addition to VFD‑driven systems, Control Innovations also supplies:
Full‑Voltage Pump Jack Panels
- Direct‑online operation
- Standardized terminal numbering
- Compatibility with POC systems
- Optional current feedback device
Soft‑Start Pump Jack Panels
- Reduced‑current startup
- Controlled torque during initial movement
- Faster response to over‑current or over‑torque conditions
These alternatives provide cost‑effective solutions where variable speed is not required.
Available Options
Control Innovations offers a range of options for pump jack 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
Pump jack control panels can be customized to match operational requirements, environmental conditions, or integration needs. Whether the application requires VFD control, full‑voltage operation, soft‑start capability, or additional field interfaces, Control Innovations can supply a complete package built for oilfield environments
