SKIN INJECTION HAZARD
To reduce the risk of serious bodily
injury, including fluid injection or splash- ing in the eyes or on the skin, always
follow this procedure whenever you shut off the pump, when checking or servicing any part of the system, when installing or changing dispensing devices, and whenever you stop dispensing.
1.Close the pump air regulator and the
2.Hold a metal part of the dispensing valve firmly to a grounded metal waste container and trigger the valve to relieve the fluid pressure, or open the drain valve (H).
Startup and Adjustment
WARNING
COMPONENT RUPTURE HAZARD The maximum working pressure of each
component in the system may not be the same. To reduce the risk of overpres-
surizing any component in the system, be sure you know the maximum working pressure of each component. Never exceed the maximum working pressure of the lowest rated component in the system. Overpressurizing any component can result in rupture, fire, explosion, property damage, and serious injury.
To determine the fluid output pressure using the air regulator reading, multiply the ratio of the pump by the air pressure shown on the regulator gauge. For example:
3 (:1) ratio x 180 psi air =
540 psi fluid output
[3 (:1) ratio x 1.2 MPa air = 3.6 MPa fluid output]
[3 (:1) ratio x 12 bar air = 36 bar fluid output]
Limit the air to the pump so that no air line or fluid line component or accessory is overpressurized.
1.With the air regulator (C) closed, open the bleed- type master air valves (A), or, if so equipped, join the quick disconnect coupler (M) to the male fitting
(L).
2.Open the dispensing valve (J) into a grounded metal waste container, making firm
3.Open the pump air regulator (C) slowly, just until the pump is running. When the pump is primed and all air has been pushed out of the lines, close the dispensing valve.
NOTE: When the pump is primed, and with sufficient air supplied, the pump starts when the dis- pensing valve is opened and shuts off when it is closed.
4.Adjust the air regulator until you get sufficient flow from the dispensing valve. Always run the pump at the lowest speed necessary to get the desired results. Do not exceed the maximum working pressure of any component in the system.
NOTES:
DNever allow the pump to run dry of the fluid being pumped. A dry pump will quickly accelerate to a high speed, possibly damaging itself. If your pump accelerates quickly, or is running too fast, stop it immediately and check the fluid supply. If the supply container is empty and air has been pumped into the lines, prime the pump and lines with fluid, or flush it and leave it filled with a compatible sol- vent. Be sure to eliminate all air from the fluid lines.
DRead and follow the instructions supplied with each component in your system.
DIf the pump will be unattended for any period of time, or to shut off the system at the end of the work shift, always follow the Pressure Relief Procedure at left.
