horizontal multistage boiler water circulation pumps booster pump

D series coal mine use multistage clear water centrifugal pumps are used for delivering clear water without solid particles and physical and chemical substances similar to that of water.

This series pumps are used in water supply and drainage system in mine, factory, and urban.

Performance Scope: Flow Q 3.7--840 m³/h

Head H 19--1000m

Model Signification:

D/DG/DF/DY-580-60/10

580: The flow is 580m³/h at design point

60:The single stage head is 60M at design point

10: The stage is 10 stages.

• D: Multi-stage horizontal centrifugal pump
• DG: Boiler feed water pump
• MD:Multi-stage wearable centrifugal pump
• DF: Multi-stage anti-corrosive centrifugal pump
• DY: Multi-stage centrifugal oil pump

Use condition:

• D:PPump can deliver clean water without solid particlep or the liquid which the chemical and physical feature are similar with water and temperature is , it is suitable for delivering water in mine and urban water projectetc.
• DG: Pump can deliver clean water without solid particle or or the liquid which the chemical and physical feature are similar with water and temperature from -20-210℃, it is suitable for boiler feed water or heat water.
• MD: Pump can deliver the neuter mineral water which solid particle percent ,1.5%(solid Dia it is suitable for steel works, mines,cities project etc.
• DF: Pump can deliver the corrosive without solid particle, which temperature is from -20-105℃.
• DY: Pump can deliver oil or oil products without solid grain,viscosity
• The inlet pressure of pumps is less than 0.6 Mpa.

Remarks:

Calculation of Installation Height

When choosing to use a pump the user should consider the installation height, that is to say the vertical distance between the liquid surface and the pump shaft center should shorter than the pump's prescribed installation height.

The pump's prescribed installation height is calculated according to the following formula:

Hsz --- The prescribed Installation Height

Ha --- The atmospheric pressure head under the condition of the use site (m)

Hv --- The vaporizable pressure head under the temperature of the pumping

Liquid (m)

Hs --- The suction piping losing head (m)

NPSHR --- NPSHR written on the performance parameters (m)
