SLD single suction multistage centrifugal pump is used for conveying clean water without solid particles and liquid with physical and chemical properties similar to clean water, and the temperature of the liquid does not exceed 80℃, which is suitable for water supply and drainage in mines, factories and cities.

Note: Flameproof motor must be used when it is used underground in coal mine.

This series of pumps meet GB/T3216 and GB/T5657 standards.

Main Purpose

Suitable for water supply and drainage in mines, factories and cities.

Performance Range

Flow (q): 25-1100m³/h

Head (H):60-1798m

Working Conditions

When selecting a water pump, users should consider the installation height of the pump, that is, the vertical distance from the sucked liquid level to the center of the pump shaft should be less than the specified installation height of the water pump, and the specified installation height of the water pump should be calculated as follows:

Hsz≤Ha-Hv-△Hs-(NPSH)r

Where: Hsz- specified installation height of water pump (m)

Ha- head of atmospheric pressure under site conditions (m)

Hv- Vaporization pressure head at pumping liquid temperature (m)

△Hs- loss head of suction pipeline (m)

(NPSH)r- the necessary cavitation allowance value given in the performance parameter table (m)
