Ebara Repair Kit Seal Guide
Seal Guide
How to read an Ebara model number and find your seal
Every Ebara pump carries its seal size inside its model number. You do not need to strip the pump or measure anything — the string on the nameplate tells you which mechanical seal and O-ring kit it takes. This guide walks through it one piece at a time.

The three parts of a model number
Every Ebara submersible model number is built from three pieces, always in the same order. Once you can see where one piece ends and the next begins, the rest of this guide is straightforward.
size
letters
code
A typical D-Series nameplate string. The red group is the one that sizes your seal.
The first number group — discharge size
The number at the front is the pump’s discharge connection, in millimetres. It tells you which pump you are looking at, and it is the part most people already recognise.
- 50 = 2″
- 80 = 3″
- 100 = 4″
- 150 = 6″
- 200 = 8″
- 250 = 10″
- 300 = 12″
Useful to know: the discharge size does not change the seal. A 4″ pump and a 6″ pump at the same kW rating take the same seal. If you find your rating in the tables below but not your exact discharge size, you are still in the right row.
The middle letters — the series
The letters name the specific model within the D range. In the US market they usually begin with D and often end with U, where the U marks the US version. You will see L, M and F appear inside the code in various combinations.
Examples you will meet in the field: DL, DLF, DLFU, DLFM, DLK, DLKWF, DLMFM, DLCMFU, DLCMKFU, DVF and DBF.
Watch for a DD prefix. DDLF and DDLFU are water-jacketed pumps. The seal is the same, but the kit build differs — so if your model starts with DD, tell us when you order and we will confirm the right contents before it ships.
There is a second Ebara family that reads the same way but sizes seals differently — the DML series (DML, SKDML, FKDML and DMLEU). If your letters contain DML rather than DL, use the DML table in step five, not the D-Series one.
Reading the performance code
The final group of digits is where the useful information lives. Read it one position at a time.
6 means 60 Hz, the US standard. A 5 here means 50 Hz.
The motor rating in kilowatts. This is the number that sizes your seal.
2 = 208/230 V · 4 = 460 V (sometimes written 450 V) · 5 = 575 V.
Voltage and frequency have no effect on the seal. The same pump at 230 V or 460 V takes the same kit.
The decimal trap. On smaller pumps the kW rating contains a decimal point, and it is easy to misread. In 100DMLEU63.72 the rating is not 63 kW — it is 3.7 kW. Read it as 6 · 3.7 · 2: 60 Hz, 3.7 kW (5 HP), 208/230 V. The same applies to 62.2 (2.2 kW), 65.5 (5.5 kW) and 67.5 (7.5 kW). If the number seems far too large for the pump in front of you, look for the decimal.
Converting kW to horsepower
Your nameplate may give horsepower while the model number gives kilowatts. These are the pairs Ebara uses, so you can move between them without doing the arithmetic.
Three worked examples
Here is the method applied to three real nameplate strings — one D-Series, and two from the DML family including a decimal rating.
- Discharge
- 150 = 6″
- Series
- DLFU — D-Series
- Frequency
- 6 = 60 Hz
- Rating
- 30 kW = 40 HP
- Voltage
- 4 = 460 V
- Discharge
- 100 = 4″
- Series
- DMLEU — DML family
- Frequency
- 6 = 60 Hz
- Rating
- 15 kW = 20 HP
- Voltage
- 2 = 208/230 V
- Discharge
- 80 = 3″
- Series
- DMLEU — DML family
- Frequency
- 6 = 60 Hz
- Rating
- 3.7 kW = 5 HP
- Voltage
- 2 = 208/230 V
Which seal your rating points to
You now have a kW rating and a series. Take the rating to the table for your family below. D-Series and DML-Series size differently, so make sure you are reading the right one.
D-Series — DL, DLF, DLFU, DLK, DVF, DBF, DDLFU
| Rated kW (HP) | Seal size | What the kit contains |
|---|---|---|
| 1.5 kW (2 HP) | 25 mm | Mechanical seal only — no O-ring kit in this size |
| 2.2 – 3.7 kW (3 – 5 HP) | 30 mm | Mechanical seal; O-ring kit available, model-specific |
| 5.5 – 11 kW (7.5 – 15 HP) | 40 mm | Both mechanical seals, O-rings, lip seal, fiber washers |
| 15 – 22 kW (20 – 30 HP) | 45 mm | Both mechanical seals, O-rings, lip seal, fiber washers |
| 30 – 37 kW (40 – 50 HP) | 45 mm | Both mechanical seals, O-rings, lip seal, fiber washers |
| 45 kW (60 HP) | Special order | Call or text 561-414-1046 to order this size |
DML-Series — DML, SKDML, FKDML, DMLEU
| Rated kW (HP) | Seal size | Faces and elastomer |
|---|---|---|
| 2.2 – 3.7 kW (3 – 5 HP) | 30/35 mm | Carbon/Ceramic upper, SiC/SiC lower, NBR |
| 5.5 – 7.5 kW (7.5 – 10 HP) | 40/45 mm | 260B / 560D design, 70 mm lower seat, NBR |
| 11 – 22 kW (15 – 30 HP) | 45/50 mm | Carbon/Ceramic upper, SiC/SiC lower, NBR |
Ebara also builds CDXU and 2CDX centrifugal pumps, which do not use this numbering. Match those by pump model — CDXU 200/506, 2CDX/I 200/50-Q1AEEQ — and confirm the kit contents before ordering.

How do I read an Ebara pump model number?
An Ebara submersible model number has three parts in a fixed order. The first number group is the discharge size in millimetres, the middle letters are the series, and the final digits are the performance code. In 150DLFU6304: 150 is a 6″ discharge, DLFU is the series, and 6304 gives 60 Hz, 30 kW (40 HP) and 460 V.
Which part of the model number tells me the seal size?
The middle two digits of the final group — the rated kW. That number, not the discharge size and not the voltage, determines which mechanical seal and O-ring kit your pump takes. In 150DLFU6304 the rating is 30 kW, which takes the 45 mm kit.
Where do I find the model number on an Ebara pump?
On the nameplate fixed to the motor housing. It is usually stamped or printed alongside the serial number, the rated output and the voltage. If the plate is corroded or painted over, the full string also appears on the original submittal paperwork and on most distributor invoices.
What does the DD prefix mean on an Ebara pump?
A DD prefix — DDLF, DDLFU — means the pump has a water jacket around the motor, which lets it run partially or fully out of the liquid. The mechanical seal is the same as the equivalent non-jacketed model, but the rebuild kit differs, so tell us your model carries the DD prefix when you order.
Does voltage or frequency change which seal my Ebara pump takes?
No. The first digit of the performance code is the frequency and the last is the voltage, and neither has any effect on the shaft or the seal chamber. The same pump wired for 208/230 V and for 460 V takes the identical kit — only the rated kW in the middle matters.
What does 63.7 mean in an Ebara model number?
It is 60 Hz and a 3.7 kW rating, not 63.7 kW. On smaller pumps Ebara writes the kW with a decimal point inside the code, so 100DMLEU63.72 reads as 60 Hz, 3.7 kW (5 HP), 208/230 V. The same pattern gives 62.2 for 2.2 kW, 65.5 for 5.5 kW and 67.5 for 7.5 kW.
What seal does a 150DLFU6304 take?
The 45 mm seal set. Reading the code: 60 Hz, 30 kW (40 HP), 460 V. Anything from 15 kW through 37 kW in the D-Series range uses the 45 mm kit, which includes both mechanical seals, the O-rings, the lip seal and the fiber washers.
What seal does a 100DMLEU6152 take?
The 45/50 mm stepped double seal. The code gives 60 Hz, 15 kW (20 HP), 208/230 V, and DMLEU belongs to the DML family rather than the D-Series. We supply that seal on its own, or as a complete kit with the matching Buna-N O-rings for the 20 HP DMLEU models.
What is the difference between an Ebara D-Series and a DML-Series seal?
Both are double mechanical seals running in an oil chamber, but they are sized differently and are not interchangeable. D-Series pumps use single-diameter seals in 25, 30, 40 and 45 mm. DML-Series pumps use stepped-shaft seals written as two diameters — 30/35, 40/45 and 45/50 mm. Check your series letters before you read the size tables.
Do Ebara repair kits include the O-rings?
It depends on the size. The 40 mm and 45 mm D-Series kits include both mechanical seals, the O-rings, the lip seal and the fiber washers for a full rebuild. The 30 mm kit has an O-ring set available but it is model-specific, and the 25 mm is supplied as the mechanical seal alone — no O-ring kit is made in that size.
