IGPDS-M Series

IGPDS-M Series

Dual Seal Grinder Pump Series

Utilizes two mechanical seals, coupled with sensor probe and seal leak detection circuitry in the panel, to provide added pump protection that can extend the overall pump life. The Series also features a reliable patented cutter system at 414,000 cuts per minute.

Order Info
  • Features

    • Vertical 1-1/4" FNPT discharge
    • Upper and lower mechanical seals minimize downtime and maintenance
    • Sensor probe designed to indicate early leak detection
    • Externally-mounted start components*
    • Corrosion-resistant brass impeller
    • Tight cutting clearances for superior grinding at 414,000 cuts per minute
    • Epoxy-coated finish for corrosion resistance and durability
    • Built-in overload protection prevents over-current and over-temperature damage
    • *The IGPDS Series requires a specific control panel or capacitor kit from FPS that is matched to the pump for proper operation and third-party approval.

    CoolingThe motor housing contains a dielectric oil to cool
    the motor and lubricate the bearings and seals.
    The pump is capable of operating with the motor
    housing partially exposed for extended periods
    of time, providing sufficient motor cooling and
    bearing lubrication. However, for the best cooling
    and motor life, the liquid level being pumped
    should normally be above the top of the cast iron
    motor cover.
