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

This guide will instructed you on how to order the right Ebara repair kit using model numbers: Shop Ebara pump kits

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.
