When choosing a pump, several aspects come into play. As you may already know, different types of pumps are suited for various purposes. For instance, the pump you would use to pump water to your garden is not similar to the one used to pump a different fluid like petroleum.
The world of pumps is vast, and most of them are manufactured according to the purpose they serve. If you are not sure about the ideal pump for your application, it is advisable to consult and specialist or vendor before purchasing. Alternatively, you can consider the following variables to make the right choice.
Your first consideration when choosing a pump is the characteristics of the liquid you intend to pump. The main properties to consider include liquid temperature, viscosity, vapor pressure, specific gravity, shear sensitivity, presence of solids, the concentration of solids, and abrasive and non-abrasive.
If the liquid has particles in it, ensure you can estimate the concentration and if there are any chemicals, notify your pump vendor. That ensures they identify a pump designed with compatible materials to avoid abrasion and corrosion issues. The liquid temperature impacts the pump materials of construction and the type offered.
Where will you station the pump? Will you install it permanently outdoors, or do you only have to use it occasionally? These are some of the queries you should answer when choosing a pump because it is prone to weather damage. For instance, if your pump is permanently outdoors, it is susceptible to freezing temperatures and may require special motors.
Other environmental conditions include dust, explosive vapors, or a hazardous environment. A knowledgeable pump vendor like PumpBiz can help you assess your environmental conditions to choose the right pump.
Which power source is available where you want to station the pump and what is the voltage? While some pumps solely use electricity, others use natural fuel like diesel. Recently some pumps have been manufactured to use compressed air and hydraulic power. Generally, you should choose a pump suited to the power source you can afford. It is even more advantageous to select a pump that can use more than one source of power to have more options.
Liquid flow rate and pressure
The total volume by the time you need to move the liquid determines the flow rate. You can calculate the pump’s differential pressure by understanding the pipe size, static lifts, friction losses, and system equipment. The flow rate determines the ideal size of a pump for your project- the higher the flow rate, the larger the pump should be.
The pressure at the inlet and outlet of the pump determines the type of pump you require for the application. Therefore it is essential to know the pressure you will be pumping against to choose the right pump.
Do you want to operate your pump at the same speed or a variable speed? Does the application need any unique controls? If yes, you need to inform your vendor to help you identify the right pump with the controls you need. These may be handy, especially in industrial pump applications.
