The VA/VS water seal series represents a high-performance sealing solution tailored for harsh industrial environments where water, oil mist, and particulates pose serious risks to mechanical systems. Manufactured from pure rubber, these seals are engineered for elasticity, resilience, and long-term sealing reliability. Whether in high-speed rotary applications or systems exposed to contamination, VA/VS seals deliver stable performance and extended service life. Material & Structure Material: Pure rubber (no metal framework) Design: VA/VS profiles provide axial or radial sealing under various installation configurations Features: High elasticity, excellent water resistance, corrosion tolerance, easy installation This fully rubberized design eliminates metal corrosion risks and ensures flexibility during dynamic equipment operation. Applications & Industry Use Cases The VA/VS water seals are suitable for applications where protection from water ingress or splash contamination is critical. Common use cases include: Application Example Equipment Pump systems Water pumps, submersible pumps Electric motors Industrial motors, servo motors Gearboxes Transmission housings, reducers Energy Wind turbines, hydroelectric equipment Automation Industrial robots, robotic arms Hydraulics Hydraulic actuators, cylinders Construction Excavators, loaders, compactors Agricultural machinery Harvesters, tractors Household appliances Washing machines, dishwashers These seals are not suitable for applications involving extremely high temperature or chemical exposure—fluoroelastomer or PTFE-based seals are better suited for such environments.

Chemical industrial pumps Our chemical industrial pumps can be made of metal such as stainless steel, bronze, titanium alloy etc. materials or plastic such as PTFE/FEP/PVDF fluoroplastic, fiberglass reinforced plastic, polypropylene plastic etc. or metal lined with plastic. Chemical pumps are widely used to convey acid, alkali, salt etc. corrosive solution. Fluoroplastic pump is used to convey sulfuric acid and has the economic cost. Polypropylene and fluoroplastic pumps are suitable to convey hydrochloric acid. Fluoroplastic pump and titanium alloy pump is suitable to convey nitric acid. Stainless steel pump and fluoroplastic pump is suitable to convey acetic acid. Stainless steel and plastic pump can be used to convey alkali such as sodium hydroxide. Stainless steel SS316 pump and bronze centrifugal pump is suitable to convey sea water or brine etc. High temperature liquids pumping usually need the pumps equipped with cooling devices. When the liquid below 120 degree Celsius is conveyed, the pump is lubricated and cooled by the pumped liquids. CZ and IH Stainless steel chemical centrifugal pumps adopt suspension structure and the pumped liquids can be up 160 degree Celsius. IHF fluoroplastic liner pump can pump the liquid up to 200 degree Celsius. When the liquid at the temperature ranges from 120 degree Celsius to 300 degree Celsius is pumped, the pump cover should have cooling chamber and seal should also have cooling liquid with double end faces mechanical seal. CQB-G high temperature magnetic pump can pump the liquids below 280 degree Celsius. For the high temperature medium above 300℃, not only the pump head part needs to be cooled, but also the suspension bearing room should be provided with a cooling system. The pump structure is generally in the form of center support, and the mechanical seal is best to use metal bellows type.
