The D pump is used to transport clear water containing no solid particles with a temperature lower than 80ºC or liquids with similar physical and chemical properties as clear water. it's applicable for water supply and drainage works in mines and cities The MD pump is used to transport acid mine water containing no solid particles with a temperature lower than 80ºCand PH between 2-4,which is applicable for mines. The DG pump is used to transport corrosive liquids,105ºC clear water or liquids with similar physical and chemical properties as clear water containing no solid particles,which is applicable for water supply of small boilers or transporting hot water or media similar as hot water. The DF pump is used to transport corrosive liquids contaning no solid particles with a working temperature range of -20ºC~105ºC,The pump's allowable inlet pressure is 0.6 Mpa. Structural: DG sires multistage pump mainly consist of four major parts:Stator,rotor,brearing and shaft seal; Stator part: It mainly consists of suction section,middle section,discharge section,guide vane and so on.those sections are clamped by tension bolts to form a working room.the DG pump's inlet is hrizontal and its outlet is vertical. Rotor part:It mainly consists of shaft,impeller,balance disc,bushing and so on.the shaft transmits power to the impeller to make it work;the balance disc is used to balance the axial force;the shaft is mounted with a replaceable bearing to protect it. Bearing part:It mainly consists of bearing seat body,bearing,bearing gland and so on.Both ends of the rotor are supported by two single-row roller bearings mounted inside the bearing body.the bearing is lubricated by grease. Shaft seal:the soft packing seal is adopted,which mainly consists of packing box body,packing,water fender and other parts on the water inlet section and the tail hood.water with a certain pressure is filled into the seal cavity for the purpose of water seal,cooling and lubrication.the water for water seal of the DG pump is from the pressure water inside the pump . Drive:the pump is driven directly by the motor through the elastic coupling,which rotates clockwise when seen from the motor end.  The D pump is used to transport clear water containing no solid particles with a temperature lower than 80ºC or liquids with similar physical and chemical properties as clear water. it's applicable for water supply and drainage works in mines and cities The MD pump is used to transport acid mine water containing no solid particles with a temperature lower than 80ºCand PH between 2-4,which is applicable for mines.

Our twin scissor tables are designed for handling long and cumbersome loads. Two (or more) scissors in an end-to-end configuration provide the required combination of platform length and lifting capacity. The stroke is achieved safely with precisely controlled synchronization and parallelism.
