Avesta SP25 900 Spray Gel Pump is intended to be used for spraying pickling gels. An adequate air-pressure, between 4-6 bars, is required for its operation. The pump is portable and it can spray from all angles. It has two separate material inlets, which makes it possible to mix an indicator with the gel. This increases the spraying visibility and reduces the formation of hazardous nitric fumes. The spraying intensity and the spray angle can be adjusted according to the need. The pump should be cleaned with water after use to remove any remaining acid.

AIR PRESSURE: is portable and can spray from all angles.
2. CONNECT THE The second material inlet can be used for the suction of the Indicator dissolved in water. This
SUCTION-INLET FOR This Indicator will then be mixed with the pickling agent in the pump, and hence will improve
THE INDICATOR the spraying visibility and also reduce the formation of hazardous nitric fumes
3. CONNECT THE The now well-stirred gel, is connected by dipping the suction hose ( the short one ) into the
SPRAY PICKLE GEL: liquid, this one can be kept in place by assembling an acid resistant pipe.
4. SPRAY-TEST: When in doubt about the spraying capacity ( after a period of non-use etc. ), always start up with a
spraying trial with water. This will clear the system and save you from unwanted problems while
spray-pickling.
5. START THE Open the air-pressure valve, and adjust the air-pressure within 4-6 bars. The pump shall now start
PUMPING to suck the liquid from the container, through the pump and lance on to the object to pickle.
Avoid folding the hose.
6. SPRAYING: Apply the pickling liquid with even strokes. The standard nozzle, Spray-jet SS11006,has a spray
angle of 110
o, and an opening of 0,6 mm, this can be adjusted according to desire.
7. STOP THE Lift up the sucking hose from the liquid and empty the system by spraying it back into
PUMPING: the container. Avoid to run the pump empty because this will destroy the membranes.
8. CLEAN THE As a final measure the water must be circulated through the pump in order to remove re-
SYSTEM maining acid which otherwise will damage and block the pump.
* AFTER USE

avoided.
* TROUBLE-SHOOTING

This measure will remove smaller contamination. Check also if the nozzle has been blocked. If
this does not work the spray-lance or the pump has to be examined closer and maybe some spare-
parts must be exchanged.
SPARE-PARTS: When exchanging spare-parts never use carbon-steel parts, they will destroy the result. Use only
he recommended parts from ARO and Spraying Systems.
