Centrifugal pumps（Hcm）（HCm-1）HCm-5）（HCm-2）
| Quantity: | |
|---|---|
Application
Suitable for use with clean water and liquids that are not chemically aggressive towards the materials from which the pump is made.
As a result of their reliability and the fact that they are easy to use, these pumps are widely used in domestic and civil applications such as the distribution of water in combination with small and medium sized pressure sets, for transferring liquids and for the irrigation of gardens and allotments. The pump should be installed in an enclosed environment, or at least sheltered from inclement weather.
Motor
※ Two-pole induction motor(n=2850 r.p.m)
※ Insulation Class B
※ Protection IP44
※ Continuous service S1
※ Thermal protector for single phase
Operating conditions
※ Liquid temperature up to 60°C
※ Ambient temperature up to 40°C
※ Total suction lift up to 8m
Component Construction
※ Pump body: Cast iron
※ Pump support: Cast iron
※ Motor housing: Aluminum
※ Impeller: Brass
※ Motor shaft: Carbon steel, AISI304 SS if request
※ Mechanical seal: Ceramic/Graphite
Product Introduction
The characteristic curve of the centrifugal pump is the inherent characteristic of the pump itself and has nothing to do with external use. However, once the pump is arranged to work in the pipeline system, its actual working state is not only related to the characteristics of the centrifugal pump itself, but also depends on the working characteristics of the pipeline. Therefore, when selecting and using a centrifugal pump, the characteristics of the pipeline must also be considered.
When transporting liquid in a specific pipeline, the pressure head He required by the pipeline changes with the square of the flow rate Qe. Drawing this relationship on graph paper is the corresponding pipe characteristic curve.
If the characteristic curve of the centrifugal pump and the characteristic curve of the pipeline are drawn on the same graph paper, the intersection M of the two lines is called the working point of the pump. When selecting a pump, the flow and pressure head corresponding to the operating point must not only meet the requirements of the piping system, but also be provided by the centrifugal pump, namely Q = Qe, H = He.
