What is a Magnetic Drive Pump?
Magnetic Drive Pumps are a great option for a number of applications. In this blog, we are going to take you through how these pumps work and why it may be what you're after.
Only then will you be able to choose the best magnetic drive pump to suit your needs.
How does a Magnetic Drive Pump Work?
A magnetic drive pump has a motor which creates the necessary momentum to pump fluids. In most pump designs, there is a physical connection between the motor and the impeller, which in turn creates suction. Those designs involve using a shaft passing through the pump housing. This shaft is then sealed by one or more mechanical seals. These pumps rely heavily on the durability of such seals - which over time wear down, and can occasionally cause failure. This results in leakage.
Magnetic drive pumps avoid this problem entirely and do not require such seals to contain a fluid or to stop leakage. A magnetic drive pump has magnets attached to the impeller, which are activated through the electro-magnetic field of a motor rather than being turned by a rotating shaft. This means there is no physical point of contact between the motor and the pump. With the use of magnets, a magnetic drive pump therefore removes the need for a shaft. With no shaft, the entire impeller can be placed inside a plastic or metal casing which is air tight and corrosion resistant.
The advantage then of a magnetic drive pump is that it has no seals which can fail, meaning no leakage. This also results in lower running costs in terms of maintenance because seals are never replaced and leakages are never having to be cleaned up.
Where are Magnetic Drive Pumps used?
Because magnetic drive pumps eliminate potential leakage, they are an excellent option for pumping liquids which are hazardous or cannot be exposed to other chemicals. Magnetic Drive Pumps are best for chemicals of a corrosive or dangerous nature.
Magnetic drive pumps are an excellent option for pumping chemicals such as:
- Methane
- Hydrochloric Acid
- Sulphuric Acid
- Sodium Sulphate
- Sodium Hydroxide
- Sodium Hypochlorite
Magnetic drives are also commonly used when:
- Unloading tankers or containers
- Batch processing sensitive chemicals
- Clearing fluids with no solid content
- Pumping fluids with low viscosity
