Knowledge Center
Written by the people who build and test the equipment. No marketing filler, just the decisions a project engineer has to make before a purchase order goes out.
Selection Guide
Both families move the same water. The choice is decided by floor space, pipework, maintenance access and how the set will be serviced in ten years.

Maintenance Guide
One seals better and costs more to replace. The other leaks by design and can be adjusted by anyone on site. Choose against the liquid and the maintenance team.

Process Guide
The pump has to move product gently and then take hot caustic at full flow. Those two requirements pull in opposite directions, and the elastomer usually loses.

Product Guide
Removing the shaft seal removes the most common leak path and the most common maintenance item. Here is where that trade is worth making and where it is not.

Design Guide
Oxygen demand sets the capacity, basin geometry sets the number of units, and the lifting arrangement decides whether maintenance needs a shutdown.

Maintenance Guide
The tube is the pump. It sets the flow, the chemical compatibility and the service interval, and it is the only part that wears.

Material Guide
The difference is molybdenum and carbon content. What that means on your plant is chloride resistance and how the material behaves after welding.

Buying Guide
Five standards, similar looking parts, different dimensions. Measuring one existing fitting saves more time than any catalogue.

Selection Guide
Above 80 degrees the usual assumptions stop working. Seal choice, expansion, venting and material all move at once, and the pump is only part of the answer.

Installation Guide
A vessel is judged by how easily it opens, how completely it cleans and how well the seal survives. All three are decided by parts that cost a fraction of the tank.
