Cast Iron Pump Rebuild Kit

Replace your sealant pump with our cast iron pump rebuild kit, complete with an impeller that works with sealcoating spray systems with vertically-aligned pumps. The impeller efficiently agitates and propels your sealant from the tank for a consistently smooth delivery through the sprayer and onto the driveway or parking lot surface.

This rebuild kit is exclusively for use with spray systems manufactured since June of 2017. Use if your AK130, AK230, AK Portable Pro, AK Drum Sprayer or AK Tote spray system came with this pump configuration:

Cast iron is strong and durable as well as an excellent choice for use in compression applications. When manufactured, a protective film forms on the surface, making it resistant to corrosion and ideal for outdoor use. Working outside in the hot sun, or in colder environments, your sealant pump has to stand up to the elements.

You can’t afford to have broken parts, cracks or other operating failures while you’re out on the job. By replacing your current sealant pump with this cast iron pump rebuild kit, you can rely on it day after day without worry.

Impeller Stuck?

The impellers can be brittle when removing and sometimes stick. You normally pry from 2 sides at the same time. Heat might help loosen up the dried up sealer that might have it stuck to the shaft but the best thing would be to purchase the solvent cleaner that will loosen the impeller prior to removing.
