Few Additional Information About Sanitary Pump that You Need to Know
The main application of any sanitary pump is for transporting meter solutions, colloids of foods, slurries and various agricultural materials that are moved in any food processing industries, where cleanliness is a very important criterion.
Following are few different types of sanitary pumps.
- Positive displacement
In case of any centrifugal pump, centrifugal force is applied to generate velocity and rotating impellers are used for increasing the velocity and that helps in pushing the fluid to output valve.
Jet pumps force the liquids through a nozzle and as a result, fluid energy gets converted into velocity energy.
In case of positive displacement pumps, rollers, impellers and gears are used for moving the liquid into a fixed cavity and where they remain stored. As the vacuum created by the pump which forces the movement of the liquid.
In airlift pumps, mixture is created of gas or air with the liquid and this air-liquid mixture has a less specific weight as compared to liquid and therefore it rises in the pipe and get discharged.
Whatever the salesmen or engineers may say about these pumps while selling them, you must remember that only two types of pumps namely centrifugal and positive displacement pumps which are mainly used for various applications, if you can understand the working of these two pumps then you can understand better how pumps are to be selected for your own applications.
The basic difference between these two pumps are that centrifugal pumps spins at very high speed and helps in transferring kinetic or centrifugal energy into the liquid in the form of pressure and velocity. Positive displacement pumps on the other hand, sends very measured amount of liquid to outlet for every rotation of the pump.
How to specify these pumps?
Following are specifications of sanitary pump needed if you ever need to place order or buy from the market.
- Maximum discharge pressure
- Maximum discharge flow
- Discharge size
- Inlet size
- Media temperature
Power sources required for the pump can be AC or DC supply, gasoline, compressed air, diesel fuel, water, hydraulic systems and solar energy. If the sanitary pump does not include any other source of power then it will provide a drive shaft for connecting to any powered pump or depend on hand or foot power.
These pumps are used for different commercial and industrial uses like horticulture, agriculture, dairy, distillery, food processing industries and pharmaceutical industries.
