Duplex Pump Control Panel Development

Project Title:
Electrical Engineer – Design of Universal Duplex Pump Control Panel

Project Overview:
We are developing a standardized duplex pump control panel to be sold as a commercial product worldwide. The goal is to finalize professional electrical engineering drawings, schematics, and a build-ready package for a compact control panel that operates two 3-phase pumps up to 25HP.

The panel must be designed as a universal platform that can operate at 208/230V or 460V using simple component changes (conversion kits), without redesigning the control system.

This is a product-development project, not a one-time building job.

Scope of Work

The electrical engineer will be responsible for producing a complete construction-ready design package based on provided specifications, including:
1. Electrical Design and Drawings
• Single line diagram
• Power schematic
• Control ladder diagram
• Terminal strip layout
• Door device layout
• Internal component layout for a 30” x 24” x 10” enclosure
2. Bill of Materials
• Detailed BOM with manufacturer part numbers
• Two configurations:
• Initial 230V configuration
• 460V conversion kit configuration
3. Logic Implementation
• Implement provided operating logic:
• OFF / HAND / AUTO modes
• Lead/Lag alternation
• Remote RUN ENABLE input
• Failover on overload
• Phase loss and reversal protection
• Anti-short-cycle timing
4. Product Standardization
• Design must be reusable and repeatable
• Support NEMA 1, NEMA 3R, and NEMA 4 enclosure options
• Use IEC components for compact footprint
• Ensure design fits within 30x24x10 enclosure
5. Compliance and Documentation
• Design suitable for UL508A panel shop construction
• Wiring standards and labeling plan
• Installation and startup documentation outline
