Engineering professionals engaged in landscape design, modern agriculture, and industrial park development often encounter such issues: Large-scale greening, nurseries, and park sprinkler irrigation involve concentrated water usage periods, significant fluctuations in water supply flow, and unstable pipeline water pressure. Distant sprinklers experience insufficient water output, while nearby areas suffer from excessive pressure that damages vegetation. If fragmented water pumps and storage tanks are used, the equipment arrangement becomes disorganized, lacks automatic pressure stabilization control, and requires dedicated personnel to manage operation and shutdown. Pressure surges and drops Uneven Sprinkler Atomization Incomplete Water Coverage Integrated pump room with water tank and constant pressure irrigation, specifically designed for landscape greening, municipal green belts, agricultural parks, and large-scale factory spray irrigation scenarios. The entire equipment is integrated with a stainless steel water storage tank, a variable frequency centrifugal pump set, a voltage stabilization control system, pipeline valves, and an integrated base. It is pre installed and debugged in the factory, and only needs to be connected to the water source and irrigation pipe network on site. 1. Core advantages of integrated pump room for constant pressure irrigation ⑴ Variable frequency constant pressure water supply Automatically adjust the speed according to the demand for irrigation water, maintain stable pressure in the pipeline network throughout the day, and ensure even water discharge from far and near nozzles to avoid uneven irrigation caused by pressure imbalance. ⑵ Integrated water storage tank Equipped with a built-in water storage unit, it can buffer the problem of insufficient water supply from the water source, ensure continuous water supply during peak irrigation periods, and adapt to municipal intermittent water supply and well water intake scenarios. ⑶ Automatic timed irrigation function The electronic control system supports setting multiple time periods for timed start stop, achieving unmanned irrigation and significantly reducing manual management costs. ⑷ Modular integration, easy installation The water tank, pump unit, and control system are integrated into the factory as a whole, which shortens the construction period and ensures a neat and standardized layout compared to on-site separate assembly. ⑸ Flexibly expand redundant pump units Large flow projects can be equipped with one in use and one backup pump set, with automatic switching in case of a single failure, ensuring uninterrupted green irrigation. 2、 Key points of project selection ⑴ Calculate the total irrigation area, number of nozzles, and determine the hourly required water supply flow rate; ⑵ Calculate the required water supply head based on the height difference of the farthest spray point and pipeline losses; ⑶ Distinguish water source types: municipal tap water/well water, and configure targeted filtration devices; ⑷ Determine the effective capacity of the supporting water tank based on the peak water consumption for irrigation. 3、 Industry selection avoidance reminder ❌ Only selecting a water pump without a water storage tank will prevent continuous irrigation when the water source is cut off or the water supply is insufficient; ❌ Using a fixed frequency water pump, the water pressure fluctuates greatly, and remote spraying cannot achieve irrigation effect; ❌ Neglecting water quality issues and not pre filtering can easily cause clogging and wear of the nozzle and pump body. Constant pressure irrigation integrated pump room, suitable for municipal greening, industrial parks, and agricultural base landscape spraying projects. Supporting the supply of standard models, customized according to site size and irrigation parameters, providing scheme design, on-site survey, and equipment debugging supporting services.

Application Success Story Bremen Regional Energy Project From river heat extraction to the delivery of both hot and cold energy, the construction of an integrated regional energy system. Location: Bremen, Germany Application: District Heating and Cooling Systems Project scale: Approximately 16 hectares of land, encompassing around 650 residential units and commercial spaces. Commissioning Date: April 2025 KSB Solution: 40 units of Etaline and Etabloc series pumps, a PumpMeter monitoring device, and an external variable frequency drive. In the past, this was a factory that produced corn chips. Today, this former industrial site is being transformed to create a vibrant neighborhood with both warm and cool spaces. In Bremen, Germany, the Uberseeinsel (Overseas Island) is being transformed from an old industrial site into a urban district spanning approximately 16 hectares, comprising around 650 residential units and various commercial spaces. Here, the challenge extends beyond simply determining "where the energy comes from"; it also involves a more practical question: how can heat and cold be delivered reliably when needed? Heating and cooling supply – must not fall through the cracks This regional energy system integrates wind energy, solar energy, and the thermal energy of the Weser River. One 5 MW river-source heat pump utilizes the Weser River as its heat source; even when the river water temperature falls below 4°C, it can still be utilized for heating supply. An ultra-large-scale thermal storage system, ice浆 energy storage, a Power-to-Heat (P2H) module that converts electrical energy into thermal energy, a regional heating and cooling distribution network, and a self-learning predictive and operational management system work together to coordinate the generation, storage, and utilization of energy. Bremen – Overseas Island Energy and Heating Solutions Even more practical is that a surface-based cold-water energy storage facility can also serve as an ice rink – thereby seamlessly integrating this energy infrastructure into the daily life of the neighborhood. However, the greater the technological complexity, the more it tests the synergy between the parties involved. Integrate dispersed devices into a single system. If the entire energy system is viewed as a building, then the heat pumps, energy storage devices, and the pipeline network each perform their respective functions; the hydraulic system acts as the underlying flow path, enabling the energy carrier to flow as needed between the generation side, the storage side, and the distribution network. This is precisely the role KSB plays in the project. The project utilizes 40 KSB Etaline and Etabloc series end-suction pumps of various specifications, each equipped with a KSB PumpMeter monitoring device; an external variable frequency drive is employed for speed regulation, enabling the pumps to adapt to changing load requirements. The core of the Energy Center: KSB Etaline series suction pumps Ensure the stable and efficient operation of the power unit This configuration provides the system with support across three areas: * Adjust operating conditions according to actual requirements * Enhance the operational reliability of the hydraulic system * Enhance operational data transparency to facilitate integration into the energy management system The pump is not merely a conveyance device here; it serves as the hydraulic foundation connecting the stages of energy production, storage, and utilization. From old industrial sites to new regional energy applications After approximately four years of design and construction, the Project No.1 and No.2 Heating Centers were put into operation in April 2025. From grain-producing factories to new neighborhoods that seamlessly integrate living, working, and leisure spaces – what is changing is not merely the use of land, but also the way energy is organized and utilized. Reliable pumping and distribution: Etabloc series pumps equipped with PumpMeter Ensure efficient and stable heating and cooling supply. As energy sources become increasingly diversified, stable and efficient operation depends not merely on a single core piece of equipment, but also on whether each segment of the flow can be properly regulated and continuously monitored. KSB provides a solid hydraulic foundation for this complex regional energy system through its pumps, monitoring devices, and speed regulation solutions.
As the pump impeller rotates, water flows into the pump through the inlet; the impeller then pressurizes the water through its rotation, causing it to flow out through the outlet. However, because a clearance exists between the impeller ring and the pump casing—and given that the water pressure within the pump chamber is higher than the pressure at the inlet—a portion of the water will flow back from the pump chamber to the inlet through this gap. This phenomenon is known as internal leakage. After a water pump has been in operation for some time, factors such as minor friction between the impeller and the wear ring, corrosion, cavitation, and abrasive wear caused by impurities in the pumped medium can lead to an enlargement of the clearance between the impeller and the pump casing. This increased clearance exacerbates internal leakage, thereby resulting in a decline in the pump's overall efficiency. Therefore, it is essential to perform regular maintenance on water pumps—such as adjusting concentricity and replacing components like wear rings and impellers—to ensure the pump maintains its high efficiency over time.
This cutting pump combines the technological advantages of major pump manufacturers featuring non-clogging, high efficiency, wear resistance, and long service life. It is equipped with a semi-open high-chromium steel impeller and high-chromium steel shear rings. Compared to traditional triangular shear rings, it has a greater flow capacity. Parameter range: Maximum flow rate: 2800m³/h Maximum head :100m Motor power :0.75kw to 160kw The product is widely applicable to: municipal engineering, livestock wastewater, domestic wastewater, and various applications requiring cutting and shredding.

The aquaculture industry relies heavily on various types of pumps. Their primary functions include: 1. Aeration. Unlike natural environments, aquaculture systems often feature high stocking densities, meaning naturally dissolved oxygen levels are insufficient. Pumps are required to circulate the water and increase its oxygen content. 2. Filtration. The presence of fish and shrimp waste, as well as uneaten feed, leads to water eutrophication and the subsequent proliferation of pathogens. Pumps facilitate water circulation to filter out impurities while introducing fresh water into the culture tanks. Aquaculture pumps are characterized by high flow rates and low head requirements. Key performance criteria include: 1. High reliability. Pump failure can lead to massive stock losses and significant economic damage, making quality and dependability paramount. 2. High efficiency. Since pumps operate continuously, electricity costs are substantial; selecting high-efficiency models helps farms reduce operating expenses. 3. Corrosion resistance. Seawater aquaculture facilities have even stricter requirements, demanding pumps capable of withstanding the corrosive nature of saltwater. With over 20 years of experience in the pump and valve industry, we offer a wide range of high-quality pumps suitable for various types of aquaculture facilities. We invite you to explore our product lineup.
