Advantages of vertical unipolar centrifugal pumps
-Directly connected with the motor. the axle of motor and pump share the same shaft. Less vibration, Low noise.
-The outlet and intet are same in diameter and the diameters are in the same line. Liquid flows smoothly with less loss.
-Removal of baseplate. just like valves, the pump can be mounted wherever on sthe pipe line.
-The whole shaft and special structurted configuration bearing runs retiably.
-The mechanical seal, which applies the configuration of enfordde circulation and no direct-ionlimited specical stru-ctrure, improves the running envinment and elongate the service life.
-Unique in stallation reduces the ocupation of pump, which saves the invest cost by 4O°/, to 6O°/o.
-Perfect design makes sure of no leakeage, long life, which saves operation cost by 5O°/o to 7O"/o.
-Adopt the high-qulity casting off, which results in high accruacy in dimension and nice-looking appearance.
Advantages of vertical monopole centrifugal pump motor
-Adopt the modinfied Two-phase induction, the structure is more reason-able and, rational and nice-looking.
-The staring torque is large, the efficiency is high, the noise is low.
-F calss insulation, which inproves the permissible temperature rise of motor, thus resulting in high ability the antioverload, strong wear-resisant, and long service life.
-Ip 55 fully close structure, which pervents dust, water drop, rain (with cover) from entering the motor to damaage the motor.
Orders for vertical monopole centrifugal pumps
1. Name, temperature, density, concentration, trellises should be clearly noted in the contract when the transpor ting
media is corrosive, so that the manufacturer can make a proper choice of material and power of motor.
2. It should be clearly noted in the contract when special requirement, for instance, capacity, suction pressure, head, motor, voltage, frequency, blast-proof etc, are made.
