Horizontal multistage pump for mine use and bolier feed water
transfer Technical Parameter: Capacity: 6 - 500 m3/h Lift
Head: 33 - 960m Drive Power: 2.2 - 180kw Rotary Speed: 980, 1480,
2950 r/min Calibre: 50 - 150mm Temperature range: -15º C - +80º C
Application: 1. Daily and fire water supply for high-rise 2. Water
supply and discharge in mines 3. Cyclic pressurization,
air-conditioning system. Type DDYDFDM multistage Pump is
single-suction, multi-stage, segmental centrifugal pump. Type D It
is provided for delivering clear water without solid particles or
other liquid which is physically and chemically similar to clear
water. The temperature of the liquid is -20º C~ 80º C...Type DY is
used to transfer non-corrosive oil and oil products without solid
particles and with viscosity less than 120 centistokes. The
temperature of the liquid is -20º C~ 150º C Type DF is used to
transfer corrosive liquid without solid particles, The temperature
of the liquid is --20~+150º C. Type DM is used to transfer clear
water or liquid which is physically and chemically similar to clear
water with limited solid particles Construction: Type DDYDFDM pumps
are horizontally installation. The direction of inlet and outlet of
Type DYDF is vertical upward except type D pump with horizontal
inlet. Type DYIIIIIIDF can be also with horizontal inlet and
outlet. The axial thrust gets balanced with the help of balance
disk. Type D, DY, DF3_40 pumps get the balanced with the help of
Symmetrically construction The shaft seal usually uses packing
seal, according to customers' requirements, mechanical seal is
used, too. Type DF85_67pumps use sliding bearings which get
lubricated with dilute--oil. The others use rolling bearings which
get lubricated with grease except type DF85-67 pump with dilute
oil. Materials of tolerance parts: Type D pump are made of cast
iron, the shaft is 45# steel. Type DY: The materials are divided
into three types: I - cast iron(the temperature in operation is
20--150º C) II_cast steel (the temperature in operation is 45--400º
C) III_stainless steel (the temperature in operation is 45--400º C)
Type DF: According to the liquid can be divided into cast steel and
stainless steel. Type DM: Anti-friction cast iron Description of
