End suction multistage pump

Product Features of End Suction Multistage Pump

◆Design pressure 10.0MPa

◆Axial suction Axial suction ensures the ideal medium flow state to achieve the best suction characteristics.

◆Radial discharge Radial discharge can choose horizontal or vertical direction of liquid discharge. Convenient for user piping.

◆Excellent axial force balance system Balance pipe and heavy-duty thrust bearing combination design that can adjust flow and pressure.

◆The rotor at the first-stage impeller adopts wear-resistant and corrosion-resistant sliding bearings lubricated by medium. The drive end adopts rolling thrust bearings lubricated by grease or thin oil. The pump operates with low vibration and low noise.

◆Mechanical seals are only required at the outlet end. Higher inlet pressure is allowed

◆The impeller is positioned and fixed with an open ring, allowing thermal expansion.

◆The sealing chamber structure is suitable for sealing forms of different structures such as single-end face, balanced type, and container type

◆The overall efficiency of the pump is high, the pump inlet diameter is large

End Suction Centrifugal Pump Structure and Performance

High efficiency and energy saving: hydraulic simulation optimization design is adopted, and the efficiency reaches the energy-saving standard.

Compact structure: the overall structure design is compact, which is easy to install and maintain.

Easy maintenance: the rear pull-out structure design does not require the removal of the pump body and pipelines for maintenance.

Low cavitation margin: some models optimize the inlet flow channel design, effectively improve the suction performance, reduce noise, and prevent cavitation.

Various materials: the pump body is usually made of cast iron or stainless steel, and the impeller can be selected from bronze, stainless steel, etc. to adapt to different media.

FAQ

1. What is the maximum head and pressure rating of the Feiyue end suction multistage pump?

The pump offers a high head of up to 800–900 meters, with a design pressure of 10.0 MPa, making it suitable for high-pressure applications such as membrane separation, desalination, and long-distance brine transportation.

2. What materials are available for the wetted components?

Flow-through components can be made from austenitic stainless steel, duplex stainless steel, Hastelloy, titanium alloy, and other corrosion-resistant metals. All materials are manufactured using precision casting to ensure durability in corrosive, high-salt, or acidic media.

3. How does the pump ensure stable operation and long service life?

The pump adopts an advanced hydraulic model, a balanced axial force system, and wear-resistant sliding bearings lubricated by medium at the first-stage rotor. The drive end uses rolling thrust bearings lubricated by grease or thin oil. These features ensure low vibration, low noise, and reliable long-term operation.

4. Is maintenance complicated for this type of multistage pump?

No. Thanks to the rear pull-out structure, maintenance can be performed without disassembling the pump body or piping. Mechanical seals are required only at the outlet end, simplifying seal maintenance. Parts replacement is straightforward and cost-effective.

5. What applications is the Feiyue end suction multistage pump suitable for?

It is widely used in seawater/brackish water desalination, high-salt membrane separation, waste acid recovery, reclaimed water reuse, boiler feed water, mining water injection, high-pressure cleaning equipment, and long-distance brine transport. For toxic, high-salt, or crystallizing media, users should provide detailed medium information before ordering to ensure correct configuration.
