Installation – Section 3.1
Mount the pump securely and position the pump at a convenient height (below the lid
height of the paint container), to allow for maintenance, visual observation, and periodic
inspection.
The wall mount bracket are included with all pumps but can be repositioned to be foot
mounted.
Exhaust silencer kits are available for these pumps if the air exhaust is required to be piped
away from the pump rather than exhausting locally through the mufflers.
The Pump Mounting Frame must be connected to a suitable earth ground to ensure that
there is no possibility of static build up.
Attach suitable flexible hoses (20 bar working pressure) to the inlet and outlet connections.
e.g. 38 mm NB Inlet and 38 mm NB Outlet hose.
Connect a suitable 3/8 NB air hose and ½” Pressure Filter Regulator to the air motor. (Filter
rated at minimum 1000 L/min)
No additional air lubrication is required as piston o-ring lubricant is applied during assembly
or repair. If an air lubricator is used to prolong piston seal life (for example continuous duty
at high pump cycle rates) then this must be maintained as the lubricant removes the piston
seal assembly grease.
Set the pump speed to a slow cycle rate and start the pump to remove any air from the fluid
circuit. Inspect for any air or fluid leaks.
Set the pump cycle rate to achieve the required paint volume and then adjust the system
back pressure regulator and pump air pressure to achieve the desired system fluid
pressure.
A Back Pressure Regulator should be mounted in the paint system return line.
The return line ‘back pressure’ regulator responds to the changes in system fluid flow
demand, (due to variable paint usage) by dynamically adjusting the paint flow rate returning
to the system paint tank, thus maintaining the set pressure.
