There are numbers of variables that can decide how long a pump can last and also how it will operate. In case you are not too sure about the selection of a pump, or before going to market you are not sure what information you should know to choose the right pump, then you are not among the minority. In this small article we have listed 7 things that you must know while selecting any pump.
- Process liquid properties
Find out what type of liquid you are going to handle with your sanitary pumps. For any liquid that you are going to handle with your pump, you must be aware about following properties of process liquid, based on which you can decide about your pump.
- Abrasive or Non-abrasive
- Liquid viscosity
- Shear sensitive
- Solids present and concentration
- Specific gravity
- Vapor pressure
- Materials of construction
What kind of materials will be compatible with your process liquid or the liquid that the pump is going to handle? You can get chemical compatibility charts, from where you can identify the right materials for the construction of your pump.
- How critical the pump is for plant operation?
If any downtime of the pump affects the productivity of your plant then you need to go for more expensive varieties of pumps. However, if downtime of pump is not a matter of concern then you can consider any less expensive pump.
- Pump inlet conditions
You need to do little analysis about the process for which you are going to use the pump. You need to make sure that pump will not starve for the liquid.
- Pump environment
You need to see where you are going to install the pump. In case the pump is going to be located outside where the environment is not controlled then then you need to make proper selection of pump that can withstand outside temperature and dust condition or make arrangement for proper housing for the motor.
- Power source availability
Make sure that necessary electrical power point is available at the location where you are planning to install the pump so that it can operate smoothly. If there is a requirement for hydraulic oil or compressed air then the same may be arranged.
- Flow rate and pressure
You can calculate flow rate of the pump based on the volume of liquid and the time needed to move. Also, by knowing the pipe length and filters, you can calculate the differential pressure.
