Ebara SKDML Double Mechanical Seal (Step Shaft)

Ebara SKDML-series pump double mechanical seal designed for step shaft applications. This replacement seal is engineered to OEM specifications for a precise fit delivering the same fit and longevity as the original parts. Its dual-seal design (upper and lower seals) provides redundant leak protection, keeping fluid away from the motor and extending your pump’s service life. Choose your correct option by pump HP range to match the stepped shaft (two seal diameters) used across SKDML/DML-family builds.

At a glance:

• Pump family: Ebara SKDML / DML step-shaft applications

• Configuration: Double mechanical seal (upper + lower) for stepped shafts

• Materials: Heavy-duty face combinations (Carbon/Ceramic/Silicon Carbide) with NBR elastomers (varies by option)

Seal Options (by HP range): Choose the correct seal size based on your pump’s HP rating.

Choose the appropriate seal option above to match your pump’s HP. Ebara’s DML/SKDML series pumps use different seal sizes for different HP ranges – 30/35mm, 40/45mm, and 45/50mm assemblies cover 3 HP up to 30 HP models.

• 3–5 HP: Ebara 30/35 mm double seal – CAR/CER–SIC/SIC–NBR

• 7.5–10 HP: Ebara 40/45 mm double seal – 260B/560D design, 70 mm lower seat, SC/SC–CAR/SC

• 15–30 HP: Ebara 45/50 mm double seal – CAR/CER–SC/SC configuration. Used in Ebara DML, FKDML, SKDML pump series for high-horsepower models.

Cross references

Replaces HCP part # F21-0C045CS0001-0, which fits HCP AF series pumps like 100AFE415 / 150AFE415 and 100AFE422 / 150AFE422 (20–30 HP models). Also compatible with AFE-type pump series such as 100(150)AFE415 MIS/MS and 100(150)AFE422 MTS/MS. (In these model numbers, “AFE” denotes the series/type, the leading “4” indicates a 60Hz unit, and the last two digits (e.g. 15, 22) represent the pump’s kW rating, which correlates to the required seal size).
