  1. Watertight Cable Entry

    The cable entry employs an anti-wicking block where each conductor is stripped and encapsulated in epoxy. This feature effectively prevents water from penetrating the motor chamber when the cable end is submerged or the cable sheath is damaged.

  2. Multi-Direction Discharge Coupling

    Discharge can be converted between vertical and horizontal directions. In pumps 7.5 HP and larger, a vertical discharge connection is supplied as standard.

  3. Motor Protector

    The motor incorporates a circle thermal protector which protects against overheating and dry-run.

  4. Top Discharge and Double Housing Design

    Designed to construct a water jacket that provides maximum motor cooling effect for continuous operation at low water level, this feature forms the cylindrical and slim shape of the pump and enables the pump to be installed in confined spaces.

  5. Submersible Motor

    Air filled motor, housed in a watertight casing, conforms to Class F insulation.

  6. C3 Ball Bearings and Hardened SS Shaft

    High quality of C3 ball bearings and the well-balanced, hardened stainless steel shaft enhance stability during continuous pumping operations.

  7. Double Mechanical Seals

    Located in the oil chamber, the device is made of quality materials with highly wear-resistant silicon carbide in lower side that provides extra protection against leakage and dry-run.

  8. Extra Protection for Mechanical Seals and Shaft

    Lip seals and shaft sleeves are utilized for additional protection against wear.

  9. High Chrome Iron Impeller

    FLO FAB patent formula, ACrS Tech is applied to all high chrome iron impellers. This technology increases wear resistance to particle abrasion.

  10. Durable Outer Jacket and Strainer

    Corrugated Outer Jacket and strainer made from 304 stainless steel provide impact resistance to harsh handling and conditions. In pumps 7.5 HP and larger, flat 304 stainless steel outer casing is provided as standard.

  11. Food Grade Lubricant

    FLO FAB adopts eco-friendly lubricant to minimize environmental impacts.
