About
RDJ Engineering
Specialists in the design, assembly, and supply of pump skids and pump components for wastewater, mining, and industrial applications.
What we do
RDJ Engineering designs and assembles pump skids — self-contained, factory-built pump systems that integrate the pump, all associated valves, instrumentation, and a control panel onto a structural steel base frame.
We also supply individual pump components — valves, filtration systems, flow sensors, pulsation dampeners, VFDs, and control panels — for clients who maintain their own maintenance and procurement teams.
Every project starts with your process data. We work from your flow rate, discharge pressure, fluid properties, and site conditions to specify and engineer the right system for the application.
System Integration
We don't just assemble components — we engineer the system. That means hydraulic sizing, instrument selection, control logic, and documentation that makes site commissioning straightforward.
Supply scope
- Complete pump skids (fabricate, assemble, test)
- Individual components (valves, instruments, VFDs)
- Control panels (custom-built to your spec)
- Spare parts and maintenance support

How we work
Engineering-first
Every skid starts with a P&ID. We engineer to your process data, not to a standard template.
Globally sourced
We specify and source components from leading global manufacturers based on technical fit, not margin.
Locally supported
Australian-based support for commissioning assistance, spare parts, and technical queries.
Documented delivery
Each skid is delivered with a full documentation package: P&ID, GA drawing, wiring diagrams, FAT records, and O&M manual.
