  • DESCRIPTION

    Hydromatic Pump Repair Kit — Seals & O-Rings by Pump Model

    Hydromatic pump repair kits are complete seal and O-ring service kits for Hydromatic pumps — choose your exact pump model from the dropdown and you’ll get the right kit for that pump. Each kit includes two mechanical seals plus a full O-ring set, built to OEM-equivalent standards or higher for the same fit and reliability as the original.

    Standard build: Carbon/Ceramic/Buna upper seal and SiC/SiC lower seal, with Buna (NBR) O-rings. Alternate face materials are available on request.

    Find your model below, then select it in the dropdown above. The explosion-proof and XP builds are listed separately because they do not take the same kit as the standard pump.

    • 4 in. discharge, standard: S4L, S4LRC, S4LR, S4B, S4K, S4Q, H4Q, S4M, S4MRC, S4P, S4HR, S4HRL, H4H, H3H, M3-4

    • 4 in. discharge, explosion-proof and XP: S4BX, S4KX, S4KXP, S4LXP, S4LVXP, H4QX, H4QXP, H4HXP, C4HXP

    • 6 in. discharge: S6L, S6LX, S6L(X), S6A, S6AX, S6AXP

    • 8 in. and larger: S8F, S8FXP, S8L, S8LA, S8LX, S8LAXP, S8LXP, S12L, S12XP, 12VL, S4T, S4TXP

    • Other series: 30MP, MMP, 40MP, 40RDP, 60MP, 60RDP, HPG200, HPGX200FD, S3HRC, S3HVX, 500ED, S4N, S3N, S4NRC, S4NX

    An X in the model number is the explosion-proof build — an S6LX is the hazardous-location version of the S6L, and it takes a different kit. A trailing P on the S8FP is a premium-efficiency rating, not explosion-proof. The 40MP and 60MP kits are not for MMP, MMPH or MPH pumps — those take a 3 in. seal, so call us.

    What’s included:

    • Upper seal: Carbon/Ceramic/Buna

    • Lower seal: Silicon Carbide/ Silicon Carbide

    • O-rings: Buna (NBR)

    Model Notes:

    • 40MP and 60MP kits are not for MMP, MMPH, or MPH pumps.

    • 40RDP and 60RDP: please specify pre-2005 or 2005-current manufacture date so we send the correct O-rings and gasket.

    • S8L models: seal configuration varies (some 25 HP units use a narrow-OD / slotted-seat seal) — confirm your build before ordering.
