Frequently Asked Questions
How do I find the right Cat Pumps seal kit for my pump?
Locate your Cat pump's model number (nameplate on the pump housing), then either search this catalog by SKU or contact ForeverPure with the pump model — we'll cross-reference the correct seal kit, including the right seal material (Buna-N, FPM/Viton, EPDM) for your fluid service.
How often should I replace Cat Pumps seals?
Cat Pumps recommends full seal replacement every 1,000–2,000 hours of continuous-duty operation. Shorter intervals apply to high-temperature, high-solids, or chemical-duty service. Inspect seals at 500 hours for early signs of wear.
Can I mix new and worn valves on a Cat triplex pump?
Cat Pumps recommends replacing inlet and discharge valves as a complete set (three of each). Mixing new and worn valves shifts hydraulic balance and can shorten the life of the new valves — replace all six valves together for the best service life.
Are aftermarket seals compatible with Cat Pumps?
Many aftermarket seals look identical to Cat OEM seals but use different elastomer formulations, dimensional tolerances, or lip geometry. Aftermarket seals often have shorter service life and void the Cat Pumps warranty. ForeverPure supplies only genuine Cat Pumps OEM parts.
Do you supply complete rebuild kits?
Yes — complete rebuild kits bundling seals, valves, v-packings, and o-rings are available for most Cat Pumps frames. Kits are matched to the specific pump model, seal material, and application. Contact ForeverPure with your pump model for the correct rebuild kit.
What is the lead time on Cat Pumps spare parts?
Most common Cat Pumps spare parts ship in 1–3 business days from ForeverPure's stocking distributor network. Specialty or less-common parts may require factory order (typically 2–3 weeks). Submit a quote request with your part number for current availability.
