Pump produced Grundfos pumps manufacturer, designed own, but none of these machines on the parameters of the modification Grundfos UP15-42F Circulator Pump not come out. However, in the monopoly issue and deficit plants were not interested in improving the parameters of the produced machines. In developing the standard, according to the Canada GOV found that demand for liquid ring expansion pumps in the country are met by 30-50%. Even connect the firm “PEX Universe” through the CMEA did not reduce the deficit, and buy a car it was only possible on the shipping instructions. Under these conditions Bessonovsky compressor plant distributed set of design documentation to customers. When there was a crisis in the country, cars of this document were also made in many enterprises, and Grundfos factory was left without customers.
By order Grundfos was developed water-packed two-stage compressor productivity 12 m3 / min with the degree of increase in pressure and expansion pump 16-20 BBH-0, 2 capacity 0.35 m3 / min in stainless steel execution. Commissioned by the Toronto Metallurgical Association drafted a expansion pump Grundfos UP15-42FR Circulator, which was entirely made of chemically hard material (titanium) for use in the technological process of melting of titanium.
From a review of liquid ring expansion Grundfos pumps of foreign firms and domestic factories that foreign firms pay considerable attention to the development of machines in this class. They are available in almost all developed countries, and some, such as Germany on their production of a large number of specialized firms.
