The secret to the durability of the High Corrosive Acid And Chemical Transfer pump is its sturdy construction. All pump materials that come into contact with chemicals must be suitable for long-term exposure without deterioration. This is essential for the life of the pump and the safe transfer of chemicals. Always follow the manufacturer’s specifications for chemical resistance when choosing a corrosive chemical transfer pump. General chemical resistance guidelines for different materials are also available.
Corrosive chemicals are liquids that attack and destroy materials that they come into contact with. Metals, stones, glass, elastomers, and even Some plastics can be easily corroded by different liquids acids, bases, and solvents. Some corrosive materials can even cause risk in case of contact with incompatible materials. For example, a lot of Inorganic acids, when in contact with an incompatible metal, can release Hydrogen gas that may present a fire and explosion hazard.
Chemical Transfer Pumps
These High Corrosive Acid And Chemical Transfer pumps are 100% sealed magnetic drive pumps. No shaft seal is used and the wheel rotates using a magnetic actuator. High-power rare earth permanent magnets used in a magnetic drive system provide high mechanical efficiency without slipping. Corrosive fluids are used in the manufacture of countless products on which we depend on a daily basis. Without the use of corrosive chemical transfer pumps, many of the products and processes that we take for granted would not be available. For example, water treatment plants use a lot of highly corrosive liquids to ensure that the water is safe to drink.
Some of these chemicals help improve taste, smell, and appearance, while others protect against lead washout from old pipes, pH adjustment, or disinfection. Steel is also used in a wide variety of items, from cars to home appliances. In the manufacturing process, hot hydrochloric acid is used to remove rust in the pickling process. Plating companies also use a variety of corrosive and toxic liquids in their processes. In the food and beverage industry, manufacturers use corrosive liquids to clean and disinfect equipment.
The best way to completely eliminate the problems caused by mechanical seals is to use a mag drive pump instead of a mechanical seal. Unlike a mechanically sealed centrifugal pump, where the motor shaft is directly connected to the impeller, a mag drive pump has no physical connection between the motor shaft and the impeller.
Magnets mounted on the motor shaft transmit motor power to magnets inside the pump that rotate the impeller via a solid barrier (often corrosion-resistant plastic). This enables the mechanical seal to be removed. Mag drive pumps can run dry for varying periods of time (depending on size) without causing damage, depending on the manufacturer and bushing material.
Meantime between failures (MTBF) is significantly better (longer lifespan) are the main areas of concern are bearings and washers. Magnetic drive pump is different from traditional hermetic pumps because they have no bearing or seal. The life cycle cost is usually lower than the cost of mechanically sealed pumps due to reduced maintenance cost (no gasket to replace), ease of installation (no water/ drain line for seals requiring discharge fluid), and Increased productivity (less downtime).
Benefits of the Magnetic Drive Centrifugal Pump
- Eliminates the release of corrosive liquids due to sealing errors.
- Increase productivity, eliminate downtime for replacing defective gaskets
- May run dry without damage depending on ring type and manufacturer
- Easier to install, no water/drain line required for discharge seal
- Low life cycle cost.
