  • DESCRIPTION

    The Barmesa BSV repair kit holds everything a 7.5 HP BSV seal service takes — the complete double mechanical seal and the full Viton O-ring set. Fits the Barmesa 3BSV-753DS (230V) and 3BSV-754DS (460V) submersible stainless vortex sewage pumps. Built to OEM-equivalent standards or higher.

    What’s in the box

    • Complete double mechanical seal, 25 mm — upper carbon / ceramic, lower silicon carbide / silicon carbide, Viton elastomers, stainless steel spring

    • Full Viton O-ring set — every O-ring the pump takes at a seal service, six in all

    The seal chamber oil is not included. Barmesa calls for turbine oil no. 32 (ISO VG-32) — refill the chamber when the new seal goes in.

    Barmesa BSV 7.5 HP — What This Kit ReplacesA BSV runs two seals in series with an oil chamber between them. Both are replaced together — a kit, not a single part.

    Part Build What it does
    Upper sealMotor side Carbon / CeramicViton, 25 mm Runs in clean oil and keeps the motor dry. It is the last line of defence — when it goes, water reaches the stator and the pump is a rewind.
    Lower sealPump side Silicon Carbide /Silicon CarbideViton, 25 mm The seal that runs in the sewage. Silicon carbide on both faces because this is where grit and solids do the damage — it is the OEM build and the hardest face pairing made.
    O-ring setSix rings Viton (FKM) Seals the volute, the oil chamber and the motor housing joints. Barmesa calls for new O-rings at every overhaul — an old ring will not reseal once it has taken a set.

    Fits these pumps

    • Barmesa 3BSV-753DS — 7.5 HP, 230V, 3 phase, 3 in. discharge

    • Barmesa 3BSV-754DS — 7.5 HP, 460V, 3 phase, 3 in. discharge

    Both are the same pump — only the motor winding changes with the voltage, so one kit covers them. Running a different BSV size? Call or text us and we will match the kit to your model.

    Applications

    • Municipal and commercial sewage lift stations

    • Wastewater transfer and effluent handling

    • Industrial process water and plant drainage with solids

    • Corrosive and abrasive duty where the 316 stainless BSV is specified over cast iron

    Oil in the chamber gone cloudy, or water in it? That is the lower seal, and it is the point to rebuild — before the upper seal lets go and takes the motor with it. Send a photo of the nameplate to info@sealhouseusa.com, or call or text 561-414-1046. No purchase required — our seal specialists will match it.
