Priming Bare Shaft Pump

Self Priming Bare Shaft Pumps are essential for various industrial and agricultural applications that require suction lifting. These pumps are designed to handle liquids with high gas content and air entrainment, making them an ideal choice for pumping liquids with low viscosity and high volume. Some shaft pumps also feature a replaceable wear plate and an external seamless adjustment for the impeller clearance, which makes them easier to maintain and repair.

Depending on the model and size, these pumps can be relatively quiet or produce significant noise during operation. They are designed to be coupled with an external motor or other drive mechanism, such as a diesel engine or hydraulic motor as they come without an electric motor. These self-priming pumps can be customised for specific requirements, such as flow rate and pressure. 

How does a self-priming bare shaft pump work?

These bare shaft pumps are a type of centrifugal pump that can automatically prime itself and draw fluid from a suction line without external assistance. Here's how self-priming pumps work:

i) The pump housing contains an impeller that rotates at high speed to create a partial vacuum within the pump casing.
ii) As the impeller rotates, it draws air and fluid into the pump housing, where a built-in air separation chamber separates it.
iii) The air is then released through the pump's discharge line while the fluid is recirculated through the impeller, compressing it and increasing its velocity.
iv) Through this procedure, a constant fluid flow passes through the pump, which fills the suction line and primes the pump. 
v) Once the pump is primed, it can maintain a steady flow of fluid through the discharge line, even if the suction line becomes partially or entirely empty.

What are the types of self-priming bare shaft pumps?

Self-priming pumps can be divided into the following types as mentioned below:-

1. Centrifugal pumps: Self priming centrifugal pumps are the most common type of shaft pump and are used for a wide range of applications, including water transfer, irrigation, and chemical processing. They are available in different designs, such as end-suction pumps, split-case pumps, and multistage pumps, and can handle fluids with varying viscosity and solids content.
2. Positive displacement pump: These pumps function by enclosing and then pushing a certain volume of fluid through the pump housing. They are ideal for handling viscous fluids, such as slurries and oils, and are available in different designs, such as gear pumps, lobe pumps, and peristaltic pumps.
3. Diaphragm pumps: A flexible diaphragm is used in these pumps to generate a vacuum that draws fluid into the pump housing. They are ideal for handling abrasive and corrosive fluids and are commonly used in applications such as chemical processing and waste treatment.
4. Jet pumps: Jet pumps use a jet of high-pressure fluid to create a vacuum that draws fluid into the pump housing. They are commonly used for shallow well applications and can be operated with a variety of power sources, including electric motors, diesel engines, and hand-operated pumps.

All these types of pumps can be easily found on our website at affordable prices, just search for the Kirloskar pump price, and you are good to go.

What are the advantages of using a self-priming bare shaft pump?

Self-priming pumps offer several advantages over other types of pumps. Here are some of the main advantages of using bare pump priming.

a) Self-priming: As the name suggests, these pumps can prime themselves without needing external assistance. This makes them ideal for applications where the pump may be located above the fluid level or where the suction line may be prone to air leaks or cavitation.
b) Reduced downtime: These shaft pumps can help reduce downtime by eliminating the need for manual priming or re-priming in case of air pockets or suction line leaks. This can lead to improved productivity, reduced maintenance costs, and increased uptime.
c) Energy efficiency: Self priming pumps can be more energy-efficient than other types of pumps, as they require less power to start up and can maintain a steady flow rate even under fluctuating suction conditions.
d) Versatility: These pumps are available in multiple designs and are capable of handling a wide range of fluids, including water, chemicals, and slurries. They can be used in a variety of applications, including construction and industrial processes.

What are the applications of self-priming bare shaft pumps?

These are versatile and can be used in a variety of settings. Here are some common applications:

i) Agricultural irrigation: These pumps can be used for irrigation, as they can easily move water from a well or other water source to crops.
ii) Municipal water systems: These pumps are used in water treatment facilities, can manage vast amounts of water and are easy to maintain.
iii) Sewage and wastewater treatment: These priming pumps are often used in sewage and wastewater treatment plants, as they can handle solids and liquids with ease.
iii) Oil and gas industry: Self-priming pumps are commonly used in the oil and gas industry for fluid transfer, dewatering, and wellpoint systems.
iv) Construction: These priming pumps are often used in construction for dewatering excavations, handling dirty water, and pumping slurry.
v) Marine applications: These pumps can be used on boats and ships for bilge pumping, ballast transfer, and fire-fighting.
