Can a Yamada pump run dry?

Yes, an AODD Yamada pump can run dry.; Only this is not recommended for PTFE fitted pumps!; And be aware of life time and energy use during dry running!

Can I dead head a Yamada AODD pump?

No pressure relief valve is needed.; DP/XDP are the best choice for dead-head applications.; Avoid using the NDP-15 series.

Can I submerse my AODD Yamada pump?

Yes, you can.; Just run an air hose from the exhaust of the pump above fluid level.; WARNING: It depends on the chemical resistance of the used materials, if you can submerse the pump into the liquid being pumped!

Is a Yamada AODD pump self priming?

Yes, our AODD pumps are self priming.; Wet suction up to 9 meters.; Dry suction best with rubber fitted pumps and at low speeds.
