Centrifugal pumps are categorized into different types and one among those is a double suction pump which is sometimes referred to as a double suction centrifugal pump. Including clear water transport or other types of similar fluid, such as water supply for cities and towns or water supply for water conservation and hydropower stations, industrial water supply systems, heat supply, etc., since the double suction centrifugal pump impeller suction point is two, the water transported is higher than other types of centrifugal pump impellers. From this case, where the number of inlet ports in a single suction pump refers to the view that the transporting capacity of a single suction pump is low compared with the transporting performance of the pump that has one inlet port. In the case of a double suction pump, on the impeller, there is a belly and two inlet ports and that implies that during operations the two inlet ports ensure that water is drawn into the impeller at the same time. Through rotation, each side of the impeller creates the centrifugal force necessary to pump the liquid, and the flow is changed by the effect of the blades. Hence two fundamental qualities that define a double suction split case pump and single suction impeller pumps are the impeller configuration and the number of inlet ports. Because industrial double suction pumps draw water in on both sides of the impeller simultaneously, such pumps have a higher level of cavitation tolerance and possess a better axial force balance.
Some common uses of double suction pumps include; cast iron, stainless steel, and bronze among other materials. Nonetheless, because of the marginal aggression of the medium transported by the double-suction pumps and the conditions in which they operate, the lifespans of double-suction pumps are relatively long which is another feature of this type of pump.
Two types of twin-suction pumps exist: Two types are horizontal split-case and horizontal double-suction centrifugal pumps. This kind includes axially split single-stage double-suction centrifugal pumps. Centrifuges with horizontal split cases.
As a manufacturer of double suction pumps, Kaiquan Pump Group can produce the following series of double suction pumps:
KQSN series single-stage, double suction, horizontal split case high-efficiency centrifugal pumps are new generation high-efficiency energy-saving double suction pump products innovatively developed by our company based on the extensive absorption of advanced technology from similar products at home and abroad. The KQSN series consists of 107 models and 508 specifications, offering a variety of performance conditions with different impeller diameters and speeds to choose from.
Kaiquan’s latest KQSN/L series vertical double suction pumps, launched in response to market demand and for structural stability, come in two support structures, completely addressing existing market product disassembly and maintenance difficulties, high mechanical seal failure rates, and high operating vibration issues. This series of products are widely used in industries such as waterworks, pumping stations, HVAC water circulation, heating hot water circulation, industrial water supply systems, and fire protection systems.
KQSU series axially split single-stage double suction centrifugal pumps have been developed by our company based on the special needs of heating, air conditioning, and hot and cold water circulation, extensively absorbing advanced foreign technology. The adoption of an excellent hydraulic model ensures the pump’s good performance and high efficiency, guaranteeing that the system operates in the pump’s efficient zone as required. The novel design results in a compact pump structure, low vibration, and convenient installation and maintenance. The excellent materials used make the pump body resistant to high pressure, meeting the static pressure requirements of high-rise or super high-rise building water circulation systems. Careful manufacturing and rigorous quality control make the product’s comprehensive performance a leader domestically.
