Case Study | ADD Model | High-Temperature Floating Oil Recovery in a Narrow Pit


Client: Metal processing factory, Aichi Prefecture
Application: Recovery of floating oil in a narrow pit (high-temperature water)
Model: ADD-15-LL (SUS316) with custom float (SUS316)

Recover floating oil from high-temperature wastewater in a narrow pit

Workers previously collected floating oil from the high-temperature pit manually using scoops.
Because of the heat and safety risks, they sought a better way to recover the oil.
Eichitwo (H2) proposed the ADD high-temperature air diaphragm pump combined with a custom recovery float.
After an on-site demo, the solution was accepted.

The float was custom-made to fit the pit, using all SUS316

The float size was tailored to fit the narrow pit. Due to the corrosive liquid and high temperature, it was made entirely of SUS316.
Particularly, machining the funnel section of the float was challenging, but it was completed successfully without issues.

Even in tight spaces and with high-temperature fluids

At Eichitwo (H2), we offer the H-FR series pump skimmers, but if the standard sizes don’t fit or you require special materials, we also provide flexible custom solutions. With extensive experience, we are ready to assist anyone facing challenges with floating oil or debris. Please feel free to contact us!
