D12-50X8 DG12-50X7 multi-stage pump is a lot of simple single-stage pump series, together. His output pressure can be great. It is a multi-stage centrifugal pump, but also rely on centrifugal force rotation of the impeller in acquiring, thereby materials. The scope of work to be gas density mechanical vacuum is drawn multistage pump 55kw, thus gradually acquiring high vacuum. Multi-stage pump is by changes in volume of the chamber to achieve suction, compression and exhaust, so it is possible to change the volume of the centrifugal environment and conditions is to ensure that the life of a multi-stage pump 200D-43X5 200D-43X3 environment and conditions product life guarantee power for the three-phase four-wire system, voltage 380 V 200d43 multistage pumps, frequency 50 Hz. Conveying the liquid medium content of not more than 40% pH 5-9 PH value in the range 30kw multi-stage pump, solid particle diameter of not more than 25mm liquid temperature of not more than 40 degrees, the lowest lift not less than 50% of the nominal head, lift the lowest not less than 20% d4630x8 rated head multistage pumps, multistage pump Shanghai Yongchang Pump from Hebei Yongchang Pump Manufacturing Limited.
