HMD series magnetic drive pumps, their rated performance and installation dimensions adopt ISO-2858 and ISO-3661 national standards.Designed and manufactured to international standards.
Structural principles and characteristics:
Magnetic transmission, no shaft seal, absolutely no leakage. The magnet uses samarium cobalt alloy magnet steel and a new magnetic circuit structure. uniqueLubrication and cooling circuits ensure good cooling and lubrication of the bearings. The materials of the flow-passing parts of the pump can be selected separately according to needs. Made of 0Cr18Ni9, 1Cr18Ni9Ti, 1Cr18Ni12, Mo2Ti, titanium alloy, nickel-based alloy, etc., it has excellent corrosion resistance. There is no bearing bracket installed at the inlet of the pump, which gives the pump excellent anti-cavitation performance. The pump casing is forged, and the isolation sleeve is made of Hastelloy C276 material with better magnetic permeability. It can also better reduce the heat caused by magnetic eddy currents and undergo a 250 kg pressure test. We use tungsten carbide for sliding bearings, bushings, and thrust washers. Not only is its hardness comparable to silicon carbide, but it is not as brittle and easy to crack as silicon carbide. It can resist the impulse caused by starting the pump very well.
The main components of the HMD type magnetic drive centrifugal pump are the pump body, impeller, inner magnetic rotor, isolation sleeve, outer magnetic rotor, Shaft, sliding bearing, bearing seat, the suction inlet of the pump is along the axis, the discharge outlet is vertically upward, the impeller is a closed structure, and the motor directly drives the external magnetic rotor of the pump to rotate. The magnetic lines drive the internal magnetic rotor to rotate together through the isolation sleeve. The coaxial impeller rotates together. It starts to rotate, thereby sucking the liquid into the suction port and discharging it from the discharge port. The specially designed lubrication and cooling circuit can allow the high-pressure liquid to circulate by itself to lubricate the sliding bearings and thrust bearings and take away friction heat and magnetic eddy current heat.
