Installed between the spacer sleeve (HZT029151800) and the flange (HZT029150391), it isolates the motor shaft from the vacuum chamber to prevent fluid leakage. Engineered for the HZT 15MBD marine vacuum sewage pump, this seal ensures reliable operation, excellent corrosion resistance, and long service life under marine sewage and vacuum toilet applications.
