DLV 600 two stage liquid ring vacuum pump in ss304 material for corrosive working condition, it is interchangeable with sihi 66327
DLV two stage liquid ring vacuum pump can work in wide inlet pressure. Compared to traditional double stage pump (suction pressure 50mbar-150mbarA), DLV pump can work in 26mbar ~1013mbarA pressure, with less energy consumption, by 15~20% lower than traditonal one.
Optional materials makes the pump possible to work in various harash environment. Here we list the usual material as cast iron, stianless steel, dual-phase steel, titianium, etc.
Wide supply range can be provided, such as bare shaft pump head, separator, and working liquid pipelines, pump aggregate with motor and base frame, pump with closed water circulation system, system with two or more stages when inlet pressure is less than 33mbar (abs.).
Single or double mechanical seal, and several flush method.
Precisely casted by stainless steel casting mould, high quality components, such as NSK/SKF bearing (users can have replaceable parts in short time worldwide), high efficiency and energy svaing.
From the performance curve above, we can find that, single stage pump suits to work low vacuum application with large capacity. While it’s capacity declines rapidly under high vacuum >200mbar, and seriesly under vacuum >100mbar. The pump works in low efficient when working under <200mbar. Howevery, the double stage pump has larger capacity in high vacuum and works efficinetly, by 30~40% higher than single stage ones. Whilst the power consumption is less. Hence DLV, as two stage liquid ring vacuum pump, is suits better to work in high vacuum.
