low head centrifugal pump|goulds centrifugal pump catalogue : manufacture Head is the height at which a pump can raise fluid up and is measured in metres or feet. We use it when specifying centrifugal pumps because their pumping characteristics tend to be independent of the fluid’s specific gravity, often … Submersible pump #1 Single-Stage Centrifugal Pump. It consists only of an impeller that rotates on a shaft within a pump casing. It is designed to produce fluid flow by using a .
{plog:ftitle_list}
A pump shaft is designed to transmit high rotational motion to the impeller as well as sustain the self-weight of the impeller along with the dynamic load of water. Most common cause of shaft failure in pump is fatigue [2]. Hydraulic forces and weight of the impeller that act on pump shaft determine its level of deflection.I have personally commissioned hundreds of pumps over my career, from small to really big and with drivers of all types ranging from steam turbines to engines and motors. Not all of these startup events went well, but from the failures came experience and from those experiences came wisdom. There are . See more
When it comes to selecting the right pump for a specific application, understanding the characteristics of different pump types is crucial. One type of pump that is commonly used in various industries is the low head centrifugal pump. These pumps are designed to efficiently move large volumes of fluid at low pressures, making them ideal for applications where high flow rates are required but the discharge pressure is relatively low.

The total head at zero flow is the maximum head, also known as the shut-off head, for a centrifugal pump. As the flow rate increases, the total head decreases. This relationship between total head and flow rate is typically represented in a plot that shows how the total head changes as the flow rate varies. Understanding this relationship is important for properly sizing and selecting a low head centrifugal pump for a specific application.
In the Goulds Centrifugal Pump Catalogue, you can find a wide range of low head centrifugal pumps that are designed to meet the needs of various industries. The catalogue provides detailed information about each pump model, including specifications such as flow rate, total head, power requirements, and construction materials. By referring to the catalogue, you can easily compare different pump models and select the one that best suits your requirements.
The Pump Type Selection Chart is another useful tool for choosing the right low head centrifugal pump. This chart provides a quick reference guide that helps you identify the most suitable pump type based on the desired flow rate and total head. By using the selection chart, you can narrow down your options and focus on the pump models that are best suited for your application.
For applications that require high flow rates, such as pumping large volumes of water or other fluids, 1000 GPM centrifugal pumps are commonly used. These pumps are capable of moving significant amounts of fluid at relatively low pressures, making them ideal for applications where high volume pumping is required. By referring to the Gould Pump Size Chart, you can easily find the right pump size that can deliver the desired flow rate at the required total head.
In addition to standard low head centrifugal pumps, there are also specialized pumps available, such as low head high discharge pumps and low head high volume pumps. These pumps are designed to meet specific requirements where high flow rates are needed but the discharge pressure is low. By selecting the right pump type for your application, you can ensure optimal performance and efficiency.
The total head at zero flow is the maximum head also called the shut-off head, the total head decreases as the flow increases. The plot of total head vs. flow for a centrifugal pump is very typical and it looks like this:
The screw pump working animation video below describes the working principle of a typical double suction, double screw pump. Screw pumps works to provide true axial progression of the liquid. It is very advantageous for pumping liquid when churning or liquid agitation is not desired.
