Chemical Transfer Pump

Chemical pumping is a process of transferring an abrasive or corrosive chemical from one container to another through an organized series of pipes and pumps. Chemical pumps are the equipment that transfers the corrosive liquid through pipes. The pumps have durable interiors and generally consist of materials that are resistant to the chemicals in transit.

• Centrifugal chemical transfer pumps

A centrifugal chemical transfer pump is a mechanical device that moves fluid through pipe chains by the means of transferring rotational energy with the help of impellers. Fluid enters the impeller along the axis and is cast outwards with the help of centrifugal force along its circumference through the vane tips. 

• Magnetic drive pumps

Magnetic drive pumps are the most applied chemical transfer pumps and are perfect for corrosive liquids. They are also very useful for pure liquids which might be hard to seal. Magnetic drive pumps drive impellers with the help of magnetic energy, eliminating any contact with the rotor and impeller. Since there are no seals, there is also less risk of any faults happening in the pump. 

• The design of magnetic drive pumps poses a very low risk of fluid leaks and vapor emissions. People working near the pump do not have any exposure to the dangers of hazardous, flammable, corrosive, and explosive fluids. 
• Magnetic drive pumps are also very reliable in comparison to centrifugal chemical transfer pumps. 
• A magnetic drive pump requires less maintenance in comparison to centrifugal pumps. The main reason for this feature is the simple design of magnetic pumps. The pumps can go over a decade without needing any repairs, and those repairs are pretty inexpensive. 
• Another benefit of the magnetic drive pump is its easy coupling feature, which eliminates the need for alignment of the pump and motor.

If you want to prime your pump, you should pour the liquid into the outlet tube or pipe and allow it to fill the pumping chamber. The pump will automatically prime itself with less effort when a foot valve is at the end of the suction line. This addition will also eliminate the need to reprime each time the pump is off. 

The biggest advantage of centrifugal chemical transfer pumps is their simplicity. These pumps do not require valves or any moving parts. So, you can use them with a wide range of materials. These pumps also transfer liquids at a faster pace in comparison to magnetic drive pumps of the same size.

Centrifugal chemical transfer pumps work on the method of forced vortex flow. This means that when a lot of liquid rotates by an external torque, the pressure rise at the head of the rotating liquid takes place. The rise in pressure is also directly proportional to the velocity of the liquid at application.
