When the situation comes to buy a chemical pump, there are many things and several applications along with pump requirements that you will need to take into proper consideration.
The materials used for the construction of the chemical pump must always be compatible enough with the chemical in it, which will be used for pumping. Acids, such as dangerous sulphuric acid and hydrochloric acid, are especially corrosive and can damage the internals of the pump.
There are two varieties in which such chemical pumps comes:
Metal Pumps – These can be termed as the ferrous or non-ferrous ones and are mainly manufactured using stainless steel, a nickel alloy, or even titanium to protect them from excessive corrosion.
Non-metallic pumps are constructed by mud pump manufacturers using the material rubber, which can be natural or synthetic in nature, ceramics, special plastic such as polypropylene and PVDF, etc. Non-metallic pumps are generally used for corrosive materials.
The selection procedure is always tough, and so the question here arises, how will you select the right chemical pump?
- Consider the application requirements thoroughly by multiple checks.
- Understanding the entire chemical media properties of the chemical pump.
- Acknowledgment of the pump’s abilities to perform the required task.
You can always consider certain required and following attributes during your chemical pump selection:
Material of Construction
- What is the chemical pump made up of?
- Environment or surrounding, and
- Maintenance of the chemical pump
Pump sizing and its day-to-day performance
- Easy flow,
- Desirable pressure,
- Temperature resistance and
- The entire piping system
Centrifugal pumps can be termed as the most frequently used pump for chemical applications, and they are a part of chemical pumps too. Due to their power of simplicity and effectiveness, they are the most preferred pump in mundane lifestyle.
However, there are ranges and varieties of chemical pumps that are suitable for chemicals, including but not limited to –
- Air operated diaphragm pumps
- Drum pumps, and
- Magnetic drive pumps
