  • DESCRIPTION

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

    Select your pump’s rated kW from the dropdown above and the page shows the exact seal for it. Each kW band uses a different seal size and a different kit build — the chart below shows which. If you are not sure of your rating, the Physical Properties tab explains how to read an Ebara D-Series model number, or call or text 561-414-1046 and we will read your nameplate for you.

    Application

    Ebara D-Series pumps are submersible non-clog sewage and wastewater pumps — DL, DLF, DLFU, DLK, DVF, DBF, DLMFMU and the water-jacketed DD models. They run in municipal lift stations and wastewater treatment plants, commercial and institutional sewage ejection, industrial sump and effluent transfer, and process and agricultural wastewater. The seals sit in an oil-filled chamber and the lower face works in solids-bearing water, which is what drives the rebuild interval.

    Working on an Ebara D-Series pump?This kit is sized by your pump’s rated kW. For a specific model or the seal on its own:

    Not sure which kit you need? See our Ebara repair kit seal guide.

    To ensure an exact match, provide your full nameplate string (e.g., 150DLFU6304) and note any water-jacket designation (DD) during checkout process under tab “Pump Model Number Notes”

  • 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
