  • DESCRIPTION

    Goulds 5K256 / 5K522 — Diaphragm Gasket

    The Goulds 5K256 / 5K522 diaphragm gasket is a high-quality replacement component designed for use in Goulds pump systems. This diaphragm gasket provides a reliable seal within the pump assembly, helping maintain proper pressure and system performance.

    These part numbers are commonly used interchangeably, making this gasket a compatible solution for multiple Goulds pump configurations. Fits the full Goulds Irri-Gator GT range of self-priming centrifugal pumps: GT07, GT10, GT15, GT20 and GT30 single phase, and GT073, GT103, GT153, GT203 and GT303 three phase, ¾ HP through 3 HP. Goulds lists this part as the diaphragm, neoprene, part number 5K256, common to every model in the series.

    Manufactured to meet original specifications, the gasket ensures a precise fit and dependable performance in demanding environments.

    Buying the parts separately? While the wet end is apart, replace the shaft seal and matching guide vane seal ring too — the shaft seal is the most common leak source. Goulds specifies the 10K10 shaft seal across the Irri-Gator GT range, a 5/8″ Type 166:
