Grundfos 96511844 HQQE Cartridge Mechanical Shaft Seal Kit
Engineered for precision repair and preventive maintenance, the Grundfos 96511844 (Model HQQE / KB016S1) is a genuine OEM mechanical shaft seal kit designed for Grundfos CR, CRI, and CRN vertical multistage centrifugal pumps. Rated for working pressures up to 30 bar (435 PSI), this cartridge-style seal kit restores factory hydraulic performance and prevents shaft leakage in high-pressure commercial and industrial fluid applications.
