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 constrictioncaused by the nozzle bore causes acceleration of the propulsionfluid and thus a vacuum in the area of the suction socket thatprimes any provided fluid or gaseous media.

• The intake quantity is a function of the propulsion fluid pressureand the nozzle bore. For the standard values for the intakequantity 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 valuessee 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 withthe media are resistant at the operating temperature accordingto the ASV-resistance guide!

Nominal Pressure (H2O, 20°C)• PN 10

Fluid Temperature• see pressure-/temperature diagram

Operating Pressure• see pressure-/temperature diagram

Size• DN 10 - DN 80

Body• PVC-U• PP• PVDF

Sealing• FPM• EPDM

Connection• DN 10 to DN 50: housing with union DIN 8063• DN 65 to DN 80: housing with spigot

Flow Direction• always in the direction of the arrow

Colour• body: PVC-U, grey, RAL 7011• body: PP, grey, RAL 7032• body: PVDF, opaque, yellowish-white

Pressure/temperature diagram

P = operating pressureT = temperatureThe pressure/temperature limits are applicable for the statednominal pressures and a computed operating life factor of 25 years.These are standard values for harmless media (DIN 2403), to whichthe valve material is resistant.For other media please refer to the ASV resistance guide.The durability of wear parts depends on the operating conditionsof the application.For temperatures below 0°C (PP < +10°C) please specify the preciseoperating conditions of the application.The rated pressure depends on the valve size and material. Forthe corresponding rated pressure value of the valve, please referto the »Order table«.

Operating noteSafe operation of the valve can only be ensured if it is properlyinstalled, operated, serviced or repaired by qualified personnelaccording to its intended use while observing the accidentprevention regulations, safety regulations, relevant standards,directives/technical regulations or codes of practice such as e.g.DIN, DIN EN, DIN ISO and DVS*. *DVS = German Welding SocietyThe intended use includes adhering to specified limit values forpressure and temperature, as well as checking the resistance. Thisrequires all components coming into contact with the medium tobe "resistant" in accordance with the ASV resistance guide.Ensure that the flow direction coincides with the directionof the arrow.Provide a damping zone of at least 5 x DN upstream anddownstream of the water-jet pump.In order to meet the requirements of accuracy for mixing or dosingwe recommend fitting suitable ASV throttle valves, ASV flowmetersand ASV diaphragm pressure gauge guards with pressure gauge.
