2100 Rubber Bellow Mechanical Seal
Most rubber bellow mechanical seals quit at 1.0 MPa pressure and 13 m/s shaft speed — the working ceiling of single-spring designs built for clean water and light circulation duty. Above that envelope, faces overheat, bellows extrude, and the seal fails inside months. The Qixing 2100 rubber bellow mechanical seal is engineered to operate where standard rubber bellow seals fail: 1.8 MPa, 15 m/s, in shaft sizes 10 mm to 100 mm.
301 Rubber Bellow Mechanical Seal
Most mechanical seal catalogues jump from 12 mm to 14 mm to 16 mm shaft size and leave OEM pump designers stuck — the shaft they actually use is 11 mm, or 13 mm, or 17 mm, and no standard catalogue seal fits. The Qixing 301 rubber bellow mechanical seal is the answer to that mismatch: 38-plus standard model codes covering every integer millimetre from 6 mm to 70 mm, plus geometry-variant codes (P and L suffixes) for cases where the shaft size is right but the gland geometry differs.
