Aurora Fire Pumps: Know Different Types of Centrifugal Fire Pumps

November 18th, 2022

Aurora fire pumps act as an integral part of a fire sprinkler system and help the system maintain adequate water supply and pressure. Powered by either electricity or diesel, their role is to provide water flow at a higher pressure to the fire protection system.

The fire pump starts whenever there is a drop in the available water pressure in the fire sprinkler system. This is generally kept below a certain threshold point. The pump intake is connected to the underground water supply or a static water source, such as a tank, reservoir, or lake.

Centrifugal Fire Pumps for Fire Protection Systems

These are the most common fire pumps that are used with most sprinkler systems. With these pumps, water pressure is built principally by the action of centrifugal force, which is the spinning action. Water enters the suction inlet and then reaches the center of the impeller. Due to the rotation of the impeller, the water experiences a certain rise in pressure. Most centrifugal pumps are able to handle large volumes of water and provide high-pressure boosts.

Below are the different types of centrifugal Aurora pumps in NYC:

• Horizontal Split-Case
  As the name suggests, horizontal split-case pumps split the water flow and allow it to enter the impeller from the opposite direction of the pump housing. It is installed with a split casing and can be opened for pump maintenance access. Also, the pump is connected to the driver with the help of a horizontal shaft.

  Such types of centrifugal fire pumps are reliable, come in an array of rated flow and pressure capacities, and are quite easy to maintain. Please note that horizontal split-case requires the most space among all types of centrifugal Aurora pumps in NYC.

   

• Vertical Turbine Pump
  Vertical turbine pumps are the only type of fire pump allowed by NFPA 20, which is standard for the installation of fire pumps with negative suction pressure. You can use these pumps with a jockey pump sensing line diagram and raw water sources, such as ponds, lakes, and rivers. Plus, vertical turbine pumps are available in a wide range of capacities and can be used with both diesel and electric drivers.

   

• In-Line Pump
  In-line fire pumps are great where space is limited. These pumps can be driven by both a vertical or horizontal shaft. Here, vertical shaft types are common and have the driver located directly above the fire pump. These shafts are typically less expensive units and take the least amount of space. However, they are often expensive to repair. This is simply because it can be difficult to lift and remove the motor to gain access to diesel fire pumps.

   

• End Suction Pump
  End suction fire pumps have a discharge outlet, which is perpendicular to the suction inlet. When compared to horizontal split-case, they are more compact and require less space in a fire pump room. These fire pumps are limited to a capacity of approximately 1,500 gpm and can be used with either an electric or diesel driver.

   

  In Conclusion

   

  As you can see, there are several types of fire pumps that can be used in a variety of situations. When your fire protection system demand exceeds what your water supply is providing, it’s time to look at Aurora pumps in NYC. These are cost-effective and energy-efficient solutions that ensure your sprinklers are always ready for action!
