Vertical Centrifugal Pump

ATO vertical centrifugal pump for sale. It is a vertical structure, the inlet and outlet have the same diameter and are located on the same centerline, and can be installed in the pipeline like a valve. Its mounting feet increase the stability of the pump.

ATO offers three-phase vertical centrifugal pumps with the power of 1 hp~100 hp. Inlet/outlet diameter 25mm (1 inch), 40mm (1~1/2 inch), 50mm (2 inch), 65mm (2-1/ 2 inch), 85mm (3 inch) and installation angle outlet 0°, 90 °, 180 ° for selection. The vertical centrifugal pump is a non-self-priming centrifugal pump with a single-stage impeller, which can be used for industrial and urban water supply, such as production line pipeline pressurization, fire water and air conditioning systems.

How Does Single Stage Centrifugal Pump Work?

When the centrifugal pump is working, relying on the high-speed rotating impeller, the liquid obtains energy under the action of inertial centrifugal force to increase the pressure. Before the centrifugal pump works, the pump body and inlet pipeline must be filled with a liquid medium to prevent cavitation.
When the impeller rotates rapidly, the blades make the medium rotate quickly, and the rotating medium flies out of the impeller under the action of centrifugal force. After the water in the pump is thrown out, the central part of the impeller forms a vacuum area. While continuously inhaling the liquid, it also continuously gives the inhaled liquid a certain amount of energy and discharges the liquid. This is how the centrifugal pump works continuously.

Features of Vertical Inline Centrifugal Pump

1. High efficiency and energy saving: CFD computational fluid dynamics is used to analyze and calculate the relationship between the pressure distribution and velocity distribution in the pump, optimize the flow channel design of the pump, ensure that the pump has an efficient hydraulic profile, and improve the efficiency of the pump.
2. Easy installation and maintenance: vertical pipeline structure, the inlet and outlet of the pump can be installed in any position and any direction of the pipeline like a valve, which is extremely convenient for installation and maintenance.
3. Stable operation, safe and reliable: The motor shaft and the water pump shaft are coaxial and direct connection, with high concentricity, stable operation, safety and reliability.
4. Stainless steel shaft sleeve: The mechanical seal position of the shaft is relatively easy to corrode. Once the direct-connected pump shaft is corroded, it is easy to cause the mechanical seal to fail. The STG pump adopts a stainless steel shaft sleeve to avoid corrosion, improve the shaft life and reduce the operation and maintenance costs.

4 Reasons to Choose a Centrifugal Water Pump

1. Flexibility
   Sanitary centrifugal water pumps can provide high flow rates and accommodate clean-in-place (CIP) procedures. They have a small footprint and flexibility in various configurations to provide a wide range of pressure outputs and flow rates. In some food-grade pump applications, sanitary centrifugal pumps can accommodate liquids containing some small solids or suspended particles, adding to their already robust product.
2. Outstanding Efficiency
   Sanitary centrifugal pumps employ an internal impeller that uses centrifugal force to "throw" material against the outer walls of the pump to force fluid out of the pump. Since lower viscosity fluids are more easily accelerated by centrifugal force, this design provides higher fluid transfer efficiency than other food-grade pump designs.
3. Cleanability
   Dairy, food, beverage and other high purity food grade pump applications require hygienic processing conditions to prevent contamination. Therefore, daily cleaning is a top priority. While relatively simple in design, sanitary centrifugal pumps and cleaning methods do vary by manufacturer.
   ATO pumps pay more attention to cleanability and hygienic design. Controlled compression gaskets, gapless internals, external mechanical seals and optimized impellers with balanced holes all ensure that the pump is thoroughly cleaned during an efficient CIP cycle. Perfectly aligned components and fittings with O-rings tightened to a predefined compression minimize elastomer product contact surfaces, which also guarantee hygiene.
4. Low cost
   Generally speaking, the upfront cost of sanitary centrifugal water pumps is relatively low. Their reliability, flexibility and high efficiency all result in a lower total cost of ownership than other food-grade pumps. Another consideration for a total cost of ownership is the maintainability of sanitary centrifugal pumps. Spare parts, maintenance or repair downtime and man-hours can significantly impact overall operating costs. A well-thought-out pump design ensures easy maintenance.

What is the Centrifugal Pump Impeller?

The impeller is the working part of the centrifugal water pump. It relies on its high-speed rotation to perform work on the liquid to realize the transportation of the liquid. It is an important part of the centrifugal pump.
The impeller is generally composed of three parts: the wheel hub, the blade and the cover plate. The cover of the impeller is divided into a front cover and a rear cover. The cover on the side of the impeller port is called the front cover, and the cover on the other side is called the rear cover.
When the centrifugal pump is started, the pump shaft drives the impeller to rotate at a high speed, forcing the liquid pre-filled between the blades to rotate. Under the action of inertial centrifugal force, the liquid moves radially from the center of the impeller to the outer circumference.
The liquid obtains energy during the movement of the impeller, the static pressure energy increases, and the flow rate increases. When the liquid leaves the impeller and enters the pump casing, it decelerates due to the gradual expansion of the flow passage in the casing, and part of the kinetic energy is converted into static pressure energy, and finally flows into the discharge pipeline along the tangential direction.
