Characteristics and operating conditions of pipeline centrifugal pumps
2026-09-18
The inline centrifugal pumps are designed based on the technical characteristics of the IS series centrifugal pumps and are a clever combination of conventional vertical pump designs. In addition, depending on the operating temperature, the nature of the pumped medium and other factors, models based on the ISG series have been created for pumping hot water, high temperatures, corrosive chemicals, and petroleum products. Products in this series are characterized by high efficiency, energy saving, low noise and reliable operation. Below we will consider in detail the features of pipeline centrifugal pumps and their operating conditions.
Vertical pipeline centrifugal pump
Features of pipeline centrifugal pumps
1. The pump has a vertical design, the diameters of the inlet and outlet holes are the same and located on the same axis, which allows it to be installed in the pipeline in the same way as a valve. The pump has a compact and aesthetic design, takes up little space and does not require large construction costs; When the protective cover is installed, it can be used outdoors.
2. The impeller is mounted directly on the extended motor shaft, resulting in short axial length and compact structure. The rational arrangement of the bearings of the pump and the electric motor allows you to effectively balance the radial and axial loads that arise during pump operation, which guarantees smooth operation, low vibration and noise levels.
3. The shaft seal adopts a mechanical seal or a combination of mechanical seals with imported titanium alloy O-rings, medium-sized high-temperature mechanical seals and wear-resistant carbide seals, which can effectively extend the service life of the mechanical seal.
4. Installation and maintenance are convenient: there is no need to dismantle the piping system - just unscrew the nuts of the pump connecting unit to remove all the rotor units.
5. Depending on the operating requirements, namely the required flow and pressure, you can use a series or parallel pump operation scheme.
6. Depending on the piping requirements, the pump can be installed vertically or horizontally.
Operating conditions for pipeline centrifugal pumps
1. Suction pressure ≤ 1.0 MPa or maximum working pressure of the pumping system ≤ 1.6 MPa, that is, pump suction pressure + pump head ≤ 1.6 MPa; pump test pressure is 2.5 MPa; When ordering, you must specify the operating pressure of the system. If the operating pressure of the pump system exceeds 1.6 MPa, this must be separately indicated when ordering, so that during manufacture the working and connecting parts of the pump are made of cast steel.
2. Ambient temperature <40°C, relative humidity <95%.
3. The volume fraction of solid particles in the pumped medium does not exceed 0.1% per unit volume, particle size <0.2 mm.
Note: If the pumped medium contains fine particles, please indicate this when ordering so that the manufacturer can use a wear-resistant mechanical seal.
