Single stage centrifugal pump has one impeller. It just has four parts: the pump casing, shaft, and impeller. They are relatively cheaper in terms of first and operating costs compared to other types of pumps because of the simplicity in design and construction; and it is suitable for most pumping duties whether for liquids, gases, etc.
Centrifugal single-stage pumps are commonly used in several industries, and this is because of their efficiency as well as reliability. Those types are widely utilized in water treatment plants, agriculture, and most industrial systems. This type of pump has only one stage and that is why they are easy to install as well as employ for many different purposes in the field of fluid management.
Nonetheless, the utilization of single-stage centrifugal pumps extends to their versatility in handling a variety of fluids ranging from clean water, through’ water containing debris such as sewage, to chemically charged fluids. It is therefore apparent why these cables are an integral part of most industrial and municipal processes. The single stage indicates the pump which has only one impeller stage to deliver fluid flow and pressure at the expected level.
It comprises a single-stage centrifugal pump which works based on centrifugal force. This works like anything in a vortex, when the impeller rotates, it actuates the kinetic energy of the fluid and pushes it outwards, to the edges of the casing of the pump. This movement increases fluid velocity and pressure, allowing it to flow through pipes. Single-stage pumps have fewer components, which reduces wear and tear and extends equipment life, lowering maintenance costs.
Sewage pumps are a type of single-stage centrifugal pump used primarily for transporting sewage or wastewater containing a large amount of solids or slurry, as well as rainwater.
Slurry pumps, another type of single-stage pump, are used for pumping abrasive, viscous, corrosive, and solid or fibrous slurries. For example, they can be used in the transportation of mineral concentrates and tailings in mining operations, as well as in the transportation of pulp in paper mills.
Double-suction pumps and most firefighting pumps also fall under the category of single-stage centrifugal pumps.
Single-stage pumps and multi-stage pumps differ in structure. Single-stage pumps have only one impeller, while multi-stage centrifugal pumps have two or more impellers.
The flow rate and head produced by single-stage pumps are opposite to those of multi-stage pumps. Single-stage pumps have a high flow rate and low head, whereas multi-stage pumps have a low flow rate and high head. Multi-stage pumps are mainly used to address the problem of insufficient head provided by single-stage pumps.
Vertical single-stage centrifugal pumps: These pumps have a spiral pump casing and a modern optimized hydraulic design. The inlet and outlet are on the same axis, and they have the same diameter.
Horizontal single-stage centrifugal pumps: These pumps have a spiral pump casing with foot support. They use a modern optimized hydraulic design, and they have horizontal suction and top discharge, with the same diameter.
Kaiquan Pump Group Co., Ltd. is a professional manufacturer of pump products. Single-stage centrifugal pumps account for approximately 80% of the market share in fluid transportation. Kaiquan has the following models of single-stage centrifugal pumps:
KQW-X series horizontal single-stage end-suction centrifugal pumps. These pumps are used for transporting clean water or other liquids with physical and chemical properties similar to water. They can also handle weakly corrosive liquids without solid particles or fibers (the flow parts can be made of stainless steel). Specific applications include:
Construction: Liquid circulation, heating and cooling water circulation in centralized heating, ventilation, and central air conditioning systems, high-rise building water supply, pressure boosting, building fire protection, and firefighting.
Industrial use: Water circulation in process systems, cooling water circulation, boiler water supply, industrial water supply and drainage.
Water supply: Water supply for water plants, distribution and boosting, swimming pool water supply, fountain water supply, agricultural irrigation, artificial spray irrigation, etc.
Environmental engineering: Filtration devices, water treatment systems, dust removal devices, recooling systems, sewage and drainage systems, and water filtration.
The sixth generation of KQL/KQW series vertical/horizontal single-stage single-suction centrifugal pumps. These pumps are used for non-corrosive cold and hot water transportation in air conditioning, heating, domestic water supply, water treatment, cooling and refrigeration systems, liquid circulation, water supply, pressure boosting, and irrigation. The medium should not contain insoluble substances exceeding 0.1% per unit volume, with particle sizes less than 0.2mm.
KQWS series stainless steel horizontal single-stage single-suction centrifugal pumps use advanced processes such as stainless steel plate stamping and welding, representing a new generation of domestic centrifugal pumps. They can replace traditional IS pumps and general corrosion-resistant pumps. They feature aesthetic appearance, lightweight structure, high efficiency, energy conservation, durability, resistance to light corrosion, and low noise. The KQWS pump is a versatile product suitable for transporting various media, including water or industrial liquids, within different temperature, flow, and pressure ranges. Its typical applications include:
Water supply: Water plant filtration, transportation, zone water supply, and main pipeline boosting.
Industrial boosting: Process water systems, cleaning systems.
Industrial liquid transportation: Boiler water supply, condensate systems, cooling and air conditioning systems, machine tool support, weak acid and alkali transportation.
Water treatment: Distillation systems or separators, swimming pools, etc.
Agricultural irrigation, medical and health care, etc.
SGL/SGW high-quality single-stage centrifugal pumps are mainly used in conventional real estate projects, non-real estate building air conditioning systems, heating systems, five-star hotels, iconic buildings, large [unidentifiable] centers, and information centers, as well as HVAC systems.
Additionally, we can also produce the XBD series of vertical and horizontal single-stage centrifugal pumps for use in firefighting systems.
