Research & development for the mining industry.

We specialise in designing new solutions to modernise machinery used in mining and mineral processing.

Our latest innovations include

sandgroper Water Free Seals

Corrosion resistant shaft sleeves. Designed to last in the harshest of mining applications.

Bulwark Bearing Isolators

The Bulwark Bearing Guard has a wear life at least twice as long as conventional bearing isolator systems.

Wolfram Shaft Sleeves

Corrosion resistant shaft sleeves. Designed to last in the harshest of mining applications.

Custom engineered solutions

We are engineers and mining specialists, with expertise in designing and servicing mining machinery.

Our goal is to create a safer work environment and develop more sustainable methods for mineral processing.

What we do

Engineering

We design custom made mining machinery using the latest engineering technology. Our specialities are slurry pumps, dewatering pumps and components.

Pump Servicing and Testing

All of our pumps are designed & serviced at our engineering headquarters in Perth, Western Australia.

Machined Castings

We don’t replicate: we innovate. We analyse the original design to make informed engineering decisions.

Training & Education

We have a wide range of pump training courses, covering topics from slurry pumping to dewatering and NPSH.

Wolfram Shaft Sleeves outlast OEM

A nickel mine in Western Australia wanted to extend the life of shaft sleeves on their mill circuit pumps.
They were using OEM shaft sleeves manufactured from cast iron. These sleeves had to be scrapped after each wear campaign due to severe erosion and corrosion frequently encountered in sites with corrosive flush water. Severe leakage occurred prior to each shut, leading to environmental and safety concerns.

Extending Pump Life, Cutting Costs for WA Nickel Mine

A Western Australian nickel mine struggled with frequent mill pump rebuilds, achieving just 600 hours of wear life on critical wet-end components. By partnering with 7D Team, they implemented engineered pump solutions featuring high chrome wear parts, a redesigned impeller, and an upgraded shaft seal.
