Pumps are used in a wide range of areas, from maritime applications to fire systems, building technologies, and industry. Since pump types vary according to each need, there are some important factors to know before making a purchase. These factors can be classified as the type of fluid, the transfer rate of the fluid, the discharge process, the source of suction, and other tools that may be needed during this process.
Effect of Fluids in Pumping Process
The type of fluid to be pumped must be known for proper product selection. In addition, the specific gravity of the fluid and its viscosity, which represents the resistance of the fluid to flow, are important. It is also essential to indicate whether the fluid contains any chemicals. If the fluid contains solid particles, the type of solids, particle size, proportion of solids in the fluid, and whether the particles are smooth or hard must also be considered. The temperature of the fluid at 20°C is another important factor. The method of fluid flow—whether dosing, transferring from one source to another, or other transfer methods—must be determined. At this stage, whether chemicals will be used, and if so, their names and concentration, are also important considerations.
Suction and Discharge Process in Pumping
The length of the suction line from the source to the pump must be considered. It is also important to know whether a self-priming pump is needed. The source of pumping may be a reservoir or a well, and a flooded suction method can also be preferred, making the chosen method a key criterion in product selection. For discharge, the orientation of the line from the start to the discharge point—horizontal or vertical—and its length must be known. Friction losses affecting the discharge process must be taken into account, including pipe type and fluid viscosity. It must also be known whether the discharge is done by open free flow or by dosing/transfer into a pressurized pipe. If dosing or transferring into a pressurized pipe, the pressure value must be known. Other factors, such as the chosen power source and its stability, are important. Depending on the energy source and type, variables like 240V, 415V, 50/60Hz, diesel, gasoline, or air must be specified. It must also be decided whether variable-speed motors, base plates, and transportation tools are needed.
Concepts to Know Before Purchasing a Pump
To make the correct product choice, it is necessary to understand certain key concepts. A base plate is a type of plate on which the pump and motor are mounted. Dosing is a controlled pumping method used to discharge the correct amount of fluid. Flooded suction is used when the fluid source is below the pump and fed by gravity; this method is preferred for centrifugal pumps. Friction loss between the pump and the fluid causes pressure loss, and certain pump parts are more sensitive to this force. Friction loss between the pipe and the fluid arises from the fluid’s movement against the pipe wall, so rougher pipes create higher friction. A self-priming pump creates an initial vacuum with its reserved fluid to help draw the fluid from the source. Variable-speed motors are used to control the flow in the system by changing the impeller speed.
