If you want to rent a water pump, you have a lot of options to choose from. Industrial pumps play an important role in different applications such as dewatering after a storm, removing or supplying water on a construction site, irrigating plants and removing debris or sludge. There are several types of pumps you can hire. When you consider their different capabilities overlap. Choosing the right pump for your needs can be challenging. However, you can read the descriptions for different water pumps to make the right decision. If you still feel overwhelmed, you should consult a professional.
Positive displacement pumps
Positive displacement pumps use a flexible diaphragm to expel materials or liquids via expansion and contraction. Older fashioned hand pumps offer a rudimentary example of the functioning capabilities of positive displacement pumps.
Positive displacement pumps are efficient when used on a large scale, especially when working with sensitive solids or high-viscosity liquids. They also do well in applications that require highly precise flow volumes or high pressure.
Centrifugal pumps
These pumps rely on a rotating impeller that spins the water inside a housing that is specially designed. The rotating action of the pump propels water through the housing and pump via centrifugal force. This causes it to slide off the end of the pump’s impeller at high speeds.
When using centrifugal pumps, you should ensure that the pump remains filled with fluid to function effectively. Nearly all pumps used in irrigation are centrifugal pumps. Other uses of centrifugal pumps include pumping water for building projects, providing a source of pressure for fire protection systems and so on.
Specific water pump types
If you need slurry pumps or when pumping liquids that have suspended solids, it is important to choose the right pump model and pump type for your application. Here are some specific pumps you can consider.
Submersible pumps
Submersible pumps are designed for underwater pumping. In most cases, submersible pump models are centrifugal. They consist of a pump and waterproof electrical motor that function as one unit. Some of the most common applications for submersible pumps include sewage services, sump pumps and so on. A significant submersible pump has the benefit of not requiring priming to function because it is installed underwater.
End suction
These pumps are the most common types of centrifugal pumps. They consist of a single impeller and a horizontal shaft. Altering the impeller type makes your pump compatible with various dirty and clean water services and solid materials.
Trash
These are common water pumps that are self-priming centrifugal pumps. They are used for dewatering at construction sites, mines and utility pits. They are designed for pumping water that contains rocks, mud, stones and other materials.
Multistage
When you want to rent a water pump, this is a great choice to consider. These pumps are well-equipped with multiple impellers and provide the additional pumping force needed for high-pressure applications. They are not a great choice for pumping mixtures of liquids and solids. Some of the common applications for these pumps include reverse osmosis applications, boiler feed water and other types of high-pressure applications.
