    • Silicon Carbide / Silicon Carbide / Viton — a lower-cost alternative build for many standard applications.

    At a Glance

    • Shaft size: 3″ (3.000″)

    • Type: T-2 (3.875 seat)

    • Seat: O-ring seat with notch

We also offer a Silicon Carbide/Silicon Carbide/Viton build at a lower price as a cost-effective alternative for many applications. Both are direct-fit; the Tungsten Carbide matches the OEM material, while the SiC/SiC option is the more economical choice.

    Ebara 260A Double Mechanical Seal — 14mm

    Item #260A

    Ebara 260A Double Mechanical Seal — 14mm (14×30, Upper + Lower)

    Ebara 260A is the direct replacement double mechanical seal for small Ebara submersible pumps built around a 14mm shaft and 30mm seat. This complete upper-and-lower set cross-references to VGM-2971 and W-14HL, and is the same proven seal we supply for Tsurumi 14×30 applications — built to OEM-equivalent standards or higher.

    Both the upper and lower seals run Silicon Carbide against Silicon Carbide (SiC/SiC) with Viton (FKM) elastomers — a hard-face, chemical-resistant build that holds up to grit, fibers, and continuous-duty submersible service far better than carbon-ceramic alternatives.

    At a glance:

    • Shaft size: 14 mm

    • Seat size: 30 mm

    • Configuration: Double seal (upper + lower)

    • Faces: SiC/SiC (upper & lower)

    • Manufacturer reference: Ebara 260A

    • Equivalent to: VGM-2971

    • Form: Seal assembly only (O-rings/gaskets sold separately)

    • Applications: Fits small Ebara submersible pumps that use the 14mm shaft and 30mm seat double-seal layout. Because it shares the 14×30 footprint, it also covers the equivalent Tsurumi and Aquascape pond and fountain pumps

    Applications

    DML Series pumps are submersible non-clog sewage and wastewater pumps running both seals in an oil-filled chamber. They are found in municipal lift stations and wastewater treatment plants, commercial and institutional sewage ejection, industrial sump and effluent transfer, and process and agricultural wastewater — solids-bearing water where the lower seal faces abrasives continuously.

    Reading your nameplate

    Ebara model numbers carry the rating in the number itself. On 100DMLEU6152: the first digit is the frequency (6 = 60 Hz), the next two are the rated kW (15 = 15 kW, 20 HP), the last is the voltage code (2 = 208/230 V, 4 = 460 V, 5 = 575 V). Read the middle two digits, find them in the kW column above, and that is your seal.

    Working on an Ebara D-Series pump?This listing is the mechanical seal on its own. If you are rebuilding the seal chamber and need the O-rings with it, check out the Ebara DMLEU Repair kit:
