In all processes for steel degassing under vacuum gases and vapors are formed that might be dangerous. Essentially CO and H2 as well as the vapors of volatile metals are released from the steel surface. Explosion protection in vacuum plants especially those that generate a large quantity of CO by the use of oxygen for decarburization so far has been assured by overpressure flaps at the metallurgical reaction vessels, alarm devices for water leakage, sensors for pressure and temperature as well as emergency venting with nitrogen. With the introduction of mechanical vacuum pumps efficient installations for gas cooling and dust separation became necessary.

A long-term strategic alliance has been established between Caprari and Peme Gourdin, two European manufacturers specialized in water centrifugal pumps. With this alliance Caprari presents the new High Flow Line, a range of products and solutions designed for pumping water at high flow rates, now available world-wide through the Caprari network.
Covering a wide range of centrifugal pumps for surface and submersible installations, Rovatti pumps are designed and manufactured for potable and industrial water supplies, irrigation, industrial and domestic sewage and waste, drainage, washing, fire fighting and artificial snow making, to name but a few. Among the latest and most significant achievements resulting from the Corporate commitment, it is important to highlight the latest developed production, certainly at the forefront of pumping technology. First of all the enlargement of both AISI 316 casted stainless steel borehole pumps Extreme series and the E series.
