The genuine Interpump / General Pump Ceramic Piston (SKU 47040409) is a precision-engineered replacement plunger, measuring 20 mm in diameter and crafted from premium alumina ceramic. Designed to match OEM specifications for Interpump and General Pump high-pressure piston pumps, this component delivers exceptional wear resistance, thermal stability, and corrosion protection, ideal for heavy-duty commercial use. It safeguards pump performance and longevity by preventing cracked or worn pistons from allowing water into the crankcase, which can degrade lubrication and cause serious internal damage. In some cases, a failing piston may even be identified by a minor leak between the pump body and manifold. Replace this ceramic plunger promptly to avoid further harm to internal seals, unloader valves, and other critical components, ensuring reliable, high-pressure operation in professional cleaning environments.
