The old pump models are BA, B type single stage single suction centrifugal pump. In the 1980s, according to the international standard and the actual situation of drainage and irrigation machinery, our country carried on the renewal and development of centrifugal pump products, and produced a series of IB and IQ single stage centrifugal pumps. 

It has been listed as national professional standard and industry standard. 

Single stage single suction centrifugal pump, water from the axial single side into the impeller, impeller only one, so it is called single stage single suction centrifugal pump. 

The utility model is characterized in that, compared with the mixed flow pump and the axial flow pump, the head is higher, the flow rate is smaller, the structure is simple and the use is convenient. 

IQ single-stage single-suction centrifugal pump (also known as light and small centrifugal pump) is designed to meet the requirements of simple structure, light weight, low price, good performance and convenient matching put forward by users. There are 84 kinds of products. 

Divided into 3 derivative series, 413 specifications and models. 

(1) performance range pump caliber 50 to 200 mm, flow rate 12.5 to 400 cubic meters per hour, lift 8 to 125 meters, supporting power is diesel engine direct connection, belt drive, motor direct connection, power 1.1 to 110 kilowatts, rotating speed 1450 to 2900 rpm. 

(2) the structural type of light and small centrifugal pump is axial suction single stage single suction suspension centrifugal pump, the pump body opens the door, the outlet is located in the center upward, the rear cover is pressure embedded, the bearing body is directly connected with the pump body, and the pump foot is located below the pump body. 

Bearings are lubricated with butter, and shaft seals are divided into three types: soft packing, mechanical seal and rubber oil seal. 

The impellers are all closed, and the transmission can be divided into two types: coupling transmission and belt transmission. 

Pump impeller steering: from the pump inlet direction, the impeller turns clockwise, when the pump and diesel engine direct transmission, for counterclockwise. 

Pump outlet can be equipped with manual pump, can remove the bottom valve, reduce hydraulic loss, and can make the pump self-priming.
