The models include BA and B single -level single -level single -suction centrifugal cardiac pumps. In the 1980s, in accordance with the actual situation of international standards and the actual discharge machinery, the centrifugal pump products were updated and replaced, and the IB and IQ single -level centrifugal pump products were produced. It has been listed as national professional and industry standards.

Single -level single -sucking cardiac pumps, water enters the impeller from a shaft, and there is only one leaf wheel, so it is called a single -stage single -suction ionized cardiac pump. Its characteristics are that compared with the mixed flow pump and axis flow pump, the raising is higher, the flow is small, the structure is simple, and the use is convenient.

IQ -type single -level single -absorbing heart pump (also known as light and small centrifugal pump) is designed for my country's national conditions and meets users with simple structure, light weight, low price, good performance and convenient support. 3 derived series, 413 specifications.

(1) Performance range pump diameter of 50 to 200 mm, flow from 12.5 to 400 cubic meters/h, 8 to 125 meters, supporting power such as diesel engines, belt transmission, electric motor direct connection, power 1.1 to 110 kW, speed 1450 ~ 2900 rpm.

(2) Structural -type light -small centrifugal pump is axial suction single -stage single -suction suspension -type centrifugal pump. The pump is opened after the pump body. The exit is located in the center. Located below the pump body, the bearing is lubricated with butter, and the shaft seal is divided into three types: soft filler, mechanical seal, and rubber oil seal. The impeller is closed, and the transmission is divided into two types: axis transmission and belt transmission. Pump leaf wheels turn: From the direction of the pump inlet, the turning of the leaf wheel is clockwise. When the pump and diesel engine are connected directly, it is counterclockwise. Pump outlet can be installed with manual pump, which can remove the bottom valve, reduce hydraulic loss, and allow pumps to suck themselves.
