By certification 
FEATURES
1. QHWB2 type mechanical seal complies with ISO3069 standard
DIN24960, GB/T6556 standards.
2. Single seal
3. Outside seal
4. Multiple springs rotating
5. Strong corrosion resistance mechanical seal
6. PTFE bellows rotation
Advantages
1. Normal mechanical seals for ideal sealing
2. Clean assembly
3. Long product lifecycle. Energy saving, environment protection
4. Installation faults are avoided, damage-free and cost-effective.
5. Excellent compensation performance functioning equivalent,
effective pressurization
6. Straightforward and easier specification for pre-assembled unit,
Time saving (reduced down-times)
7. Individual adaptation was subject to pump's design and style.
Customized products (OEMs) are available.
8. Wide applicable to program about conversion and retrofit
Conditions and Operating range
1. Pressure: 0~0.83MPa
2. Temperature: 20° C~ 120° C
3. Shaft diameter: d=30 to 60 mm
4. Rotation speed: n ≤4000r/min
5. Applicable medium: Strong acid, strong oxidizer
and other strong corrosive solution. Not apply to
alkali, hydrofluoric acid and solution with impurity.
Note: the sizes of a shaft are connected to the
operation pressure and temperature.
Materials
Metal parts: Metal 316, 304, 2Cr13 multiple Springs
Friction Elements: Silicon carbide or hard alloy,
Auxiliary seal: PTFE bellows
