Case Study | ADD Series | Trolley Unit with Built-in Compressor

A major chemical manufacturer approached us with a request to transfer urea water from land to ships docked at the port.

The required specifications were:

• Transfer rate of 200 L/min
• Self-priming and resistant to dry running (since urea tends to crystallize)
• 30 m total head
• Mobile unit with both pump and compressor mounted on a trolley

We handled the request from design stage and delivered a custom-built unit.

Since long-distance transfer via hose was expected, a pulsation damper was also included in the unit.

We selected the appropriate compressor based on the customer’s requirements and delivered the unit as a complete, ready-to-use package.

Although the customer had considered other types of pumps, they ultimately chose our air diaphragm pump unit for its durability: tolerating dry runs, handling slurry, and more, even if it meant including a compressor.

As shown in this case, we offer flexible design and fabrication of custom units and systems using our pumps.

If you need more than just a pump, such as a trolley-mounted setup, please feel free to contact us.
