Split Case Pumps in DUBAI UAE
Although split-case pumps are very similar to end-suction pumps, split-case pumps differ in that the casing, suction nozzle, and discharge nozzle are all housed in a common housing. In addition, the body design is such that it makes split case pumps ideal for applications with high water flow requirements. Split centrifugal pumps usually come in two single-suction models or two single-suction impellers supported between bearings. The pump is centrally split, with suction flanges and opposite casing, which simplifies maintenance.
The use of pumps are: commercial-office-residential-industrial-hospitals and so on. Therefore, Marineland brings you the best in Dubai and Sharjah.
The pump housing is the outer shell of the pump to isolate the internal components from the outside atmosphere while maintaining the desired fluid pressure and preventing leakage. Depending on the type of pump, there are different casing structures and each performs a different function.
Split case pumps with vertical or horizontal split series provide easy access to internal parts and are easy to maintain. Stay with us to learn how split case pumps work in Dubai, their types and other benefits.
What are split case pumps?
Split-case pumps have housings that separate, making it easier for technicians to access pump internals without disturbing the drive. These pumps have an inter-bearing design where the impeller has bearings on both sides. As a result, it puts the impeller under much more stress, making split pumps more efficient than frame pumps.
Types of split case pumps in Dubai
There are two types of split case pumps based on the dividing axis:
1. Vertical split case pumps
Due to their design, vertical split case pumps have a minimal footprint compared to other pumps with similar capacities. However, they are not as popular as they tend to be less efficient. Vertical split cases are suitable for conveying fluids with high pressure and high temperature.
2. Horizontal split case pumps
Horizontal split case pumps are the most common because they are more efficient (above 90%) and more affordable. With an inter-bearing configuration, these pumps are stable at variable speeds and can operate with different suction orientations.
Advantages of split case pumps
Split case pumps are expensive and not as flexible as standard pumps. However, they are still used in various industries due to their reliability and performance. In addition, features such as inter-bearing designs enable these pumps to continue operating for longer periods of time without the need for frequent maintenance. Also, they are the only type of conventional pump that has a double suction impeller. This allows the pump to draw fluid from both sides of the impeller, reducing the load on the pump bearings and providing excellent NPSH values.
Major applications of split case pumps
Vertical split pumps are commonly used in industrial applications such as oil and water supply, ballast and cooling. On the other hand, horizontal split-case pumps are the most common pumps and are used to pump low-viscosity fluids at low to medium pressure, such as water. Hence, these types of split case pumps are used in urban pumping stations and cooling tower stations, where they need water at a constant pressure and the pump needs to continue working for a longer period of time.
Another use of split case pumps in Dubai is fire extinguishing in the fire department. Split pumps are needed by the firefighting network (including boxes and sprinklers).
According to the NFPA (National Fire Association of America) standard, the firefighting network must be equipped with pumps to be able to operate after a long period of time from the time of delivery and presentation to the employer. These pumps include pump jacks and standard electrical panels (including command and power lines).
If there is no diesel generator to generate electricity in emergency situations, it is mandatory to use diesel pumps according to NFPA20 standard. These pumps are produced in the following two types, from the capacity of 50 to 1500 gallons per minute (gpm).
1. UL listed end suction pumps
2. UL listed and FM approved horizontal split case pumps
Split case pumps or double-case pumps
Fire pumps are a part of water automatic fire extinguishing system and they work through electricity-diesel.
This device is connected to the supply pipes of the urban water network or a static source (reservoir) and provides the required water pressure for fire extinguishing systems during fires and emergencies. These pumps are listed by UL and FM global standards.
Pumps that are sold as listed and approved pumps are tested and reliable.
1. These pumps are designed and the materials used to make them are globally approved. Their bearing life, screw tension and shaft deviation in these pumps have been calculated and confirmed.
2. The machine shaft shear stress is approved by UL and FM experts.
3. The pumps are electrostatically covered and able to withstand twice the maximum pressure without exploding or creating porosity in them.
4. They have UL and FM performance test.
5. The color of the body of each part of the device is from approved raw materials to prevent corrosion of the pump body over time.
Horizontal single and two stage split case fire pumps for fire fighting applications. NFPA-20 design. UL listed and FM approved.
Indicator features of split case pumps in Dubai
Double suction impeller provides better NPSH and less axial thrust. The housing is usually double bolted to reduce radial bearing loads. The pump has two seals, both of which have suction pressure seals.
The use of split case pumps in the UAE
Split Case Pumps in DUBAI UAE are usually used at higher flow rates than end suction pumps. Used for cooling water, plant make-up water (make-up water simply refers to water added to plant processes to compensate for losses), potable water distribution, fire pumps, pipelines and other major process streams. Takes.
Flowing fluid in Split Case Pumps in DUBAI UAE
Water and relatively thin liquids (do not pump thicker oils do). Not usually used for liquids containing solids. Available in alloy for corrosive service.
Advantages of using split case pumps in Dubai
This type of pump gives a much higher flow rate than end suction pumps. The double suction impeller has no axial load and is less likely to cause cavitation.
Pressure from 40 to 355 + PSIFlow from 150 to 5000 GPM Drive Electric or Diesel
Rohrpumpen centrifugal fire pumps feature a heavy duty shaft and short bearing span that minimizes shaft deflection, providing longer packing and bearing life and lower maintenance costs, while It requires less floor space. RP split case fire pumps are manufactured to NFPA 20 standards and are listed by Underwriters Laboratories (UL) and approved by Factory Mutual (FM).
