There are many different kinds of water pumps from small units for water transfer, to larger ones for industrial, mining or agricultural purposes. Which pump you need will differ according to the specific application it is required for. Goscor Power Products has been in the industry long enough to know which water pump will be needed.
Here are some of the most frequently asked questions when it comes to water pumps and how to know which is the right type to choose.
We can. In order to answer this question in absolute detail though, we always need to know a few things first;
1. Do you have an existing pipe? If so, what size and type is the pipe?
We need to know this because the diameter of the pipe determines the amount of friction that will be generated over the distance. The type of the pipe is important too because the smoother the pipe inside, the less friction will be created. Both these components are critical when calculating the head of the pump required.
2. Does the water pump need to overcome lift (elevation)?
We need to know if the water pump needs to be able to move the liquid up and over a certain elevation and if so, what is the estimated elevation in meters. Elevation is calculated from where the pump is standing when it starts to pump the water, to where the water is required.
3. In the case of irrigation, what type of sprinkler is being used?
For our customers that need a water pump for irrigation, we need to know what kind of sprinkler system is being used. We also need to know how much water is required per sprinkler and how many sprinklers will be needed for one machine.
Once our customers have given us the answers to questions 1, 2 and 3, we can then recommend what kind of pump is needed. We put all the information together into one mathematical calculation to determine the total head and flow rate. Once we know this, we can take this data and select the pump accordingly.
There are two types of pumps that can be recommended for pumping trash or slurry water. Knowing which one to recommend is a matter of knowing if the solids in the water being pumped will be hard solids or soft solids.
We would recommend a semi-trash pump for pumping water with soft solids while we would recommend a full-trash pump for water with hard solids in. We may even recommend a diaphragm pump for slurries or sewage waste too.
Both semi-trash and full-trash pumps are difficult to prime due to the heavy items in the water. We therefore always suggest using a foot valve or non-return valve on the suction side of the pump.
No. Once a pump has been selected for a specific function, or duty point, one needs to be aware that it does not mean it can work on another site with different parameters. At Goscor Power Products we recommend and install a specific type of water pump depending on the exact needs of that site. Each site would present a new set of parameters and operational measures that would need to be considered.
Yes. Chemical or liquid fertilizer pumps are also mere transfer pumps but the important part to know is that the pipes and pumps need to be corrosion resistant. In the case of customers needing to move this kind of liquid, we would recommend using a thermoplastic pump with stainless steel fasteners to prevent corrosion.
