Vertical multistage high-pressure pump group CDLF+CDH

Short Description:

A high-pressure series pump is a pump assembly device that connects multiple pump units in series. By connecting in series, the liquid passes through various pump units and is gradually pressurized in each unit, thereby generating higher pressure than a single pump. This type of pump usually has a higher head, which can meet the needs of long-distance and high head fluid transportation. At the same time, it also has the characteristics of compact structure, stable operation, and high efficiency, which can maintain good performance under different working conditions.

It can be used for long-distance water transportation in hydraulic engineering, such as in large water pipeline systems, to transport water from the water source to distant water use areas. In hydropower stations, it is used to pump water from downstream to upstream, achieve the recycling of water resources, or provide high-pressure water sources for turbines to improve power generation efficiency. In the construction of high-rise buildings, high-pressure transportation of concrete is used to transport the mixed concrete to the high-rise floors through pipelines. It can also be used in building fire protection systems to provide high-pressure firefighting water in the event of a fire, ensuring effective firefighting.

Product Description

High Pressure pump CDLF+CDH pumps are new generation, high efficiency, non-self-priming vertical multistage centrifugal pumps(Abbr. as pumps). It referred to European standard, adopted entirely new industrial design, efficiency achieved MEI≥0.7. It is energy saving, low noise, environment friendly, compact design, beautiful shape, light weight, easy for service, high reliability.

CDLF+CDH are two pumps in serial produce 48 bar high pressure.

CDLF+CDH pump supplier water, CDH pump is a high pressure pump, which specially designed for high pressure applications. This sample only provides the technical information of the high pressure pump.

CDLF+CDH form a double pump system in series, which can generate 46bar high pressure. The first CDLF pump is a feed pump, and the second CDH pump is a high-pressure pump specially designed for high-pressure applications. This sample only provides the technical information of the high-pressure pump. The CDH pump is a non-self-priming, vertical multistage centrifugal pump with a standard motor installed. The motor is directly connected to the pump shaft through the pump head with a coupling. The tension rod bolts fix the pressure resistance and flow passage parts between the pump head and the water inlet and outlet section. The pump inlet and outlet are in the same line with the pump bottom, The rotation direction of the pump is opposite to that of the feed pump, and the flow direction of the conveyed liquid is opposite because of the counter alarm in the flow passage chamber, which makes the pressure resistant cylinder and mechanical seal only bear the outlet pressure of the feed pump, thus improving the reliability.
