Model SLD pump consists of four parts, stator, rotor, bearing and shaft seal:

1.Stator consists of inlet, middle and outlet sections and the guide vane etc., with the take-up bolt tightly clamping all sections to form a working room. The inlet of  it stands horizontally while the outlet vertically upward.

2.Rotor  consists of the shaft, impeller, balancing disk and muff etc., the shaft passes the power to the impeller to have it work; the balancing disk balances the axial force; and replaceable muff is mounted on both sides of the shaft to protect it.

3.There are rolling and sliding bearings:

The rolling bearing consists of bearing seat, bring and bearing gland and uses grease for lubrication.

The sliding bearing consists of bearing body and cover, liner, dust-proof disk, oil leveller, oil throwing ring etc., and uses thinned oil for lubrication.

4. The shaft is sealed with stuffing and the shaft seal consists of the sealing contents, stuffing, baffle. The liquid in the sealing work-room functions water-sealing, water-cooling and water lubricating and the water for water-sealing comes from the pressure water inside of the pump.

A mechanical seal can also be used upon the requirement from users.

In addition, the pump is directly actuated by the prime mover through the elastic clutch and viewing from the prime mover, moves CW.
