Water-jet pump SP 820 Advantage • simple maintenance • no moving parts • very low wear • low investment costs • can also be used for aggressive media • very good mixing effect • high operating reliability • low space requirement Application • chemical plants • water treatment • electroplating plants Intended Use • for mixing, dosing and delivering fluids • for evacuating air in pipes and containers • for pumping out containers or pits Function • Propulsion fluid flows in the main flow direction through a nozzle fitted in the water-jet pump. The cross-section constriction caused by the nozzle bore causes acceleration of the propulsion fluid and thus a vacuum in the area of the suction socket that primes any provided fluid or gaseous media. • The intake quantity is a function of the propulsion fluid pressure and the nozzle bore. For the standard values for the intake quantity please refer to the diagram. Intake Quantity • For standard values see diagrams. Design • We recommend an empirical determination by adapting the nozzle bore to the desired operating point. For standard values see diagrams. Attention • The nozzles are provided as standard without bore! Flow Media • Technically pure, neutral or aggressive fluid or gaseous media, provided that the valve components coming into contact with the media are resistant at the operating temperature according to the ASV-resistance guide!
