Product Q&A
Q:What is a concrete pump pipe gasket?
A:
A concrete pump pipe gasket is a sealing component installed at the connection between delivery pipes, elbows, rubber hoses, and pipe clamps. It helps prevent concrete slurry leakage during pumping operations.
Q:Is this product the same as a concrete pump seal kit?
A:
No. A pipe gasket is mainly used at concrete delivery pipeline connections. A concrete pump seal kit normally includes seals used in S valves, cylinders, agitator shafts, and other pump components.
Q:What materials are available?
A:
Rubber, natural rubber, polyurethane, PU, and customized sealing materials are available according to the application and working conditions.
Q:What is the difference between rubber and polyurethane gaskets?
A:
Rubber gaskets generally provide good flexibility and sealing performance. Polyurethane gaskets normally offer higher wear resistance and deformation resistance. The appropriate material depends on the pipeline, pressure, clamp structure, and operating conditions.
Q:What sizes are available?
A:
We supply DN50, DN65, DN80, DN100, DN125, DN150, DN180, DN200, and customized specifications.
