DF-type pump is a single suction, multistage, segmental and corrosion-resistant centrifugal pump for conveying corrosion-resistant liquid without solid particles. Transmission medium temperature is -20 ℃ ~ 105 ℃, suction pressure allowed is 0.6MPa.
Range of Parameters
Flow rate: Q2 ~ 336m3 / s
Head: H84 ~ 666m
Direction of Rotation
View from the prime motor end, pump rotates clockwise
Materials of main parts The wetted parts of pump are made of cast steel and cast stainless steel. When ordering, proper material, seal form and pump structure should be selected on the basis of the name, concentration, inlet pressure, temperature, corrosivity of the transmission medium.
Supporting Range Pump, motor, and base are matching supply, which can be equipped with common base or original base. Attachments (including discharge cone, gate valve, check valve) and spare parts (including the impeller, seal rings, guide vane sets, balance disc, shaft set) are also provided by the factory.
II. Model Description
DF25 - 50 × 5
"DF" - refers to a single suction, multistage, segmental and corrosion-resistant centrifugal pump.
"25" - refers to the pump flow rate (m3 / h).
"50" - refers to single-stage head of pump (m).
"5" - refers to series.
III. Structure Description
DF stainless steel multi-stage pump is of horizontal installation. Except that the suction port direction of DF155-30 pump is horizontal, the rest of the pump suction port is vertically upward. The discharge direction of all DF pumps is vertically upward. Packing seal is generally adopted, mechanical seals can also be applied as customer’s requirement. Except that sliding bearing of DF85-67 type and rolling bearing of DF155-67 type pump are lubricated by thin oil, and the rest all adopts the rolling bearing and is lubricated by oil. Except that the axial force of DF3-40Ⅱ pump is balanced away by the mode of impeller symmetrical arrangement, the rest are balanced away by the balance disc.
