Accessories- Material Filters
When using an extrusion gun (e.g. dispensing a bead) it is typicallynot necessary to filter the product if application tip diameters arelarge enough.

Click to edit Master subtitle styleAirless spraying is based on the application of pressure to a fluid witha high-pressure pump.The high-pressure fluid is directed trough a smallorifice. As the material exists the orifice and goes to ambient pressure,the material rapidly expands and breaks into fine particles, a process commonly referred to as “atomization”. The size of the spray orifice determines the amount of fluid filtration required. Impurities, dried particlesand other particles that are larger than the orifice will plug its opening. Therefore most spray systems require some degree of fluid filtration.

• Make sure to select a filter with an orifice smaller than the diameter of the tip orifice.• Select a large filtering surface if flow rate is important this will reduce cleaning frequency.

Accessories- Material FiltersChoosing the right Filter
It is necessary to balance the appropriate size spray tip with the proper meshedfluid filter:• To avoid lost production due to clogging and cleaning of spray tips.• To avoid damaging or changing the material and its characteristics by having too fine of filtration.• To minimize material pressure drop over the filter(finer filter has more pressure loss than a more coarse filter element).• To reduce the plugging of the filter(the finer the screen the more quickly it plug). High pressure can cause a plugged filter screen to collapse or break in some instance.• To reduce the required frequency of filter cleaning or replacement. When filtering a material the filter must be continuously maintained to be effective

Accessories- Follower Plates
The follower plates are used with the single or two post ram, is designed to provide positive priming pressure for pumping high viscosity materials.It also isolates the material in the drum from air while the drum is emptied,simultaneously protecting the material from outside contaminants.As thematerial is evacuated from the drum, the plate cleans the sides of the drum and minimises any material waste at the bottom of the drum.As material viscosity increases the amount of flow from a pump decreases.Single & Two post rams with follower plates are recommended when viscosities are higher than 3000 cPs. Follower Plates should be considered with any material that does not easily seek its own level in a drum. Usually we usefollower plates with flat wiper seals with viscosities up to 25,000cPs. Over theseviscosities we advise the use of double flat wipers or double “Tube type” wipers

Accessories- Lifts & Rams Selection
IR/ARO single and two post rams are designed to make easy and quick replacement of pails and drums by the lifting of the pump. The use of rams with follower plates improves pumping results by exerting a continuous and modulating pressure on thesurface of the pumped material.
•Single rams will have a maximum thrust of 240 daN
•Two post Rams standard 480 daN
•Two post rams Extra Heavy-Duty 700 daN• daN= decaNewton

Downstream
Fluid Pressure Regulators are used to reduce the fluid pressure delivered from a pump.Regulators are designed to deliver constant fluid pressure based upon the inputs orsetting of the regulator. Fluid regulators should be placed as close as possible to thepoint of application. Fluid filtration placed before the fluid regulator will protect it fromcontamination. Fluid regulators can be controlled remotely through a pneumatic signalor manually.
The ARO I.D.L. Fluid Regulator features smooth consistent pressure regulation witheasy-turn adjustment. Patented easy-access seat plug permits immediate service accessto the regulator’s ball and seat. Patented “floating” ball and seat design maintains properregulation, even during significant fluctuations in line pressure.

Accessories- Fluid RegulatorsHow does it work!
ARO
Downstream
• The fluid regulator closes and stops fluid flow when the pressure in the hose downstream of the regulator is greater than the set regulator pressure (in free flow situation with no back pressure the regulator will not work.• The input fluid pressure should be approximately 40% higher than the regulated pressure.• For good control in a pneumatic regulated system a stable air supply is required.• Fluid supply pulsation should be minimised to help assure good regulator function.

Accessories- Pulsation Dampeners
Are used to control and minimise the pulsation that result from a pressurised system’s stroking action. They increase system efficiency, performance, and pump life; decrease maintenance costs and down-time; and protect pipes, meters, valves and instrumentation from pulsation, vibration, and hydraulic shock. Most pulsation dampeners use a bladder or bellows to separate the process fluid from a compressible gas. During the pump’s discharge stroke, fluid pressure displaces the bladder or bellows and compresses the trapped gas. During the following cycle, the momentary interruption of fluid flow causes the compressed gas to expand, forcing the bladder or bellows to push the accumulated fluid back into the discharge line.
