Centrifugal pumps are very simple devices designed to move fluids. These pumps work by converting mechanical energy into kinetic energy and then to pressure. These energy conversions occur in the two main pump components, the impeller and the stationary involute. There are three categories used to classify centrifugal pumps based on the type of flow they produce. These are axial flow, mixed flow and radial flow.
Centrifugal pump manufacturers can design products for different applications such as marine, water, low flow irrigation and industrial. There are also different types of products like a self-priming or a vertical centrifugal pump. These versatile pumps are relatively simple in construction, inexpensive and require low maintenance. However, they can be inefficient under certain conditions. For an efficient pumping system, a good centrifugal pump design is very important.
Before selecting centrifugal pumps, you should consider the following:
1. Review factors like fluid flow rate, pump size, head requirements, and pump performance curves to choose energy-efficient centrifugal pumps.
2. Find the right centrifugal pump for an application.
3. Compare products from different centrifugal pump distributors.
Find a centrifugal pump manufacturer that offers good technical information or resourcesKnowing centrifugal pumps basics is important to select a proper pump product. Because the impeller component is a main consideration in the design of this type pump, manufacturers can offer pumps with different impeller designs that can perform efficiently under different conditions like high flow rate with low head. A centrifugal pump manufacturer should provide charts and performance curves for different pump models. Before selecting a product, check out the performance curve, which shows the efficiency, capacity and the total head of the pump model.
Know the type of centrifugal pumps you require for an applicationDifferent applications/media require different types of pumps. You can find some distributors that offer only marine centrifugal pumps. Other manufacturers may carry wider selections of products like centrifugal industrial pumps, centrifugal water pumps and priming centrifugal pumps. For a marine or industrial application, the pump may be NiAl bronze, which is a good material choice because of its corrosion resistance properties.
Buy centrifugal pumps from vendor that offer quality products and good pricesMany distributors or vendors provide online catalogs of centrifugal pumps. By browsing through online catalogs from different vendors and comparing centrifugal pump prices, you can narrow down your selection of products and find some good deals.
- A high-pressure centrifugal pump is a good choice for applications that require high discharge pressures and flows. These pumps can discharge at a rate of 100 gallons per minute and can produce heads well over 200 feet.
