Xylem Gaskets, Seals & O-Rings

Pumps only perform as well as the seals that keep fluid where it belongs. Xylem is a global water technology company whose family of pump brands includes Jabsco, Flojet, Rule and Goulds Water Technology, so its gaskets, seals and O-rings are built for the specific housings, shafts and covers found in those pumps. This page focuses on those sealing components. For the wider range of Xylem products, visit the Xylem brand page.

Sealing Parts Designed Around Xylem Pumps

Xylem's marine pump heritage is a major part of this category. Jabsco is described by Xylem as a leading maker of products for the leisure marine market, including water systems, engine cooling pumps and marine waste systems. Rule is known for submersible bilge pumps and float switches. These pumps run in wet, salty, vibration-heavy environments, so a worn lip seal or a flattened cover gasket can quickly turn into a leak or a loss of prime.

Typical replacement parts for these pumps include:

• End cover gaskets: flat gaskets that seal the pump cover against the housing. Many fit a number of Jabsco flexible impeller pump models.
• Lip seals and bearing seals: shaft seals that keep water out of the bearing area and fluid out of the drive end. They are matched to specific pump series.
• O-rings: small elastomer rings used on pump shafts, covers and fittings. Some Jabsco Water Puppy pumps use a reusable O-ring style end cover seal.
• Service and repair kits: many Jabsco kits bundle an impeller with a gasket, lip seal or O-rings and hardware, so the seals are replaced together with the wear parts.

Flojet and Jabsco macerator repair kits follow the same approach. They combine a nitrile impeller with fiber gaskets, rubber O-rings and impeller lubricant so the housing can be reassembled properly.

Goulds Water Technology Seal Components

Goulds Water Technology adds a residential, commercial and agricultural side to Xylem's sealing parts. The brand traces its roots to Seneca Falls, New York, and is credited with casting the world's first all-metal pump in 1849. Its parts catalog includes mechanical seals, shaft seal assemblies, gaskets, and seal and O-ring kits for well and booster pumps. Some O-rings are made from Viton and are specified for NSF-61 drinking water applications, which matters when a pump supplies potable water.

What to Check Before You Order

• Match the pump series: seals and gaskets are often specific to a model series, so check the number on the pump head or housing.
• Consider the elastomer: Viton, nitrile and neoprene each tolerate different fluids, temperatures and chemicals. Choose one that suits what the pump moves.
• Replace as a set: when you open a pump to change an impeller, renewing the gasket, lip seal and O-rings at the same time helps prevent a repeat repair.
• Look at the shaft: a groove or scoring on the shaft can wear a new lip seal quickly, so inspect it during service.
