14、4 Supply Arrange Pump and installation instructions are available. Notes on Order-placing 1. Name, temperature, density, concentration, trellises should be clearly noted in the contract when the transporting media is corrosive, so that the manufacturer can make a proper choice of material and power
15、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. Advantgaes S Motor and pump share the same shaft to reduce vibration and noise. Diameters of inlet and outlet suctio
16、n are the same with pump body supported by the base to ensure reliable and stable operation. Single shaft and bearings of special design make the operation reliable. pecial type of mechanical seal enforcing cirulation regardless of ro- tation directions can improve the working environment and elongate the life. Delicate installation structure is more space economical which can re -duce const ruction cost 40% to 60%. Perfect design assures of l
