  • DESCRIPTION

    Ebara DLFU / D-U Seal Kit — Select by Rated kW

    Order the correct Ebara DLFU / D-U mechanical seal kit for your Ebara D-Series submersible pump by selecting your pump’s rated kW (HP shown for reference). Each kW range corresponds to a specific seal size/build, and some kits include the remembered “full rebuild” contents (dual seals + O-rings + lip seal + fiber washers).

    ***Important Note: Please click “physical properties” tab below for information on how to read Ebara D-Series model numbers (for seal sizing) or click our Ebara Repair Kit Seal Guide

  • PHYSICAL PROPERTIES

    How to read Ebara D-Series model numbers (for seal sizing)

    Example model: 150 DLFU 6304

    1) Discharge size (first number group)

    150 = discharge size.
    Common sizes:

    • 50 mm (2″) | 80 mm (3″) | 100 mm (4″) | 150 mm (6″) | 200 mm (8″) | 250 mm (10″) | 300 mm (12″)

    2) Model letters (middle group)

    DLFU = the specific D-Series model.
    In the U.S., D-Series models usually start with “D” and often end with “U” (U = U.S. version). You’ll frequently see L, M, and/or F within the code.
    Examples seen in the field: DLFM, DLK, DLMFM, DVF, DBF, DLKWF, DL, DDLF (water jacket), DLFU, DLCMKFU, DLCMFU, and more.

    3) Four-digit performance code (last group)

    6304 helps select the correct mechanical seal and O-ring kit.

    • Position 1: Frequency (e.g., 6 = 60 Hz)

    • Positions 2–3: kW rating (drives seal/O-ring sizing; kW corresponds to HP on U.S. nameplates)

    • Position 4: Voltage code

      • 2 = 208/230 V

      • 4 = 460 V (sometimes shown as 450 V in docs)

      • *5 = 575 V

    kW = HP quick reference (positions 2–3)

    • 1.5 kW = 2 HP

    • 2.2 kW = 3 HP

    • 3.7 kW = 5 HP

    • 5.5 kW = 7.5 HP

    • 7.5 kW = 10 HP

    • 11 kW = 15 HP

    • 15 kW = 20 HP

    • 18 kW = 25 HP

    • 22 kW = 30 HP

    • 30 kW = 40 HP

    • 37 kW = 50 HP

    • 45 kW = 60 HP

    Why this matters

    The kW digits (positions 2–3) and the voltage code (position 4) are key to matching the correct mechanical seal set and O-ring kit for your exact pump build.

    Quick tip:
    Have the full string from your nameplate (e.g., 150DLFU6304) and, if possible, the serial number. Share those with us and we’ll confirm the exact seal and O-ring kit you need—fast. Call us today
