FAQs

Frequently Asked Questions

A-100NA Specifications

  • Does the A-100NA have any output alarms?

    The A-100NA pump can be wired for open collector output alarm (TFD or FVS alarm condition.)

  • Is the A-100NA rated NEMA 4X?

    No. The A-100NA pump enclosure is rate NEMA 3R (IP23).

  • Is the A100NA rated NSF 61?

    The A-100NA pump is rated NSF 61.

  • What is suction lift?

    Suction lift is the maximum vertical distance that a pump can draw liquid from a source below the pump centerline. This is typically measured in feet or meters of water.

    Suction lift is limited by the atmospheric pressure. Atmospheric pressure is the force exerted by the weight of the air above the Earth's surface. As the liquid level in the suction line drops, the atmospheric pressure decreases. This decrease in atmospheric pressure reduces the suction force that the pump can generate.

    If the liquid level in the suction line drops too low, the atmospheric pressure will be insufficient to overcome the vapor pressure of the liquid. Vapor pressure is the pressure exerted by the vapor of a liquid in equilibrium with its liquid state. When the vapor pressure of the liquid equals the atmospheric pressure, the liquid will begin to vaporize.
