GENERAL DESCRIPTION
The 650503 Portable Pumping System includes fittings, wall / cart
bracket, regulators, siphon tube, gauges and hardware. It is intended to
be used in conventional HVLP (High Volume Low Pressure) spray systems. These systems generally operate using low material pressure
(less than 30 p.s.i.), and when complimented with the proper gun, it produces a “soft spray”.

Read the information included with the spray gun for system settings
and operation information.
The diaphragm pump uses stainless steel balls and seats, and PTFE diaphragms and is designed to be used with waterborne paints. The gun
and low pressure air and material hoses are not included. (Continued)

GENERAL DESCRIPTION (CONTINUED)
Consult your sales representative for the proper low pressure gun and
other accessories which will best match the application.
This system includes a wall mount bracket which can alsobeattachedto
cart pn 67074.
Theory of operation:
HVLP (High Volume, Low Pressure) is a spray process which uses a
high volume of air (15 - 22 c.f.m.) at a low pressure (10 p.s.i. or less) to

atomize the material, producing both high transfer efficiency (the total
percent of material that actually stays on the intended surface) and a
quality finish. The air cap of the HVLP gun injects air into the fluid after it
passes through the orifice restriction.Thelowvelocityofthematerialbeing sprayed minimizes the over-spray and bounce-back that is associated with conventional air spray.

OPERATING AND SAFETY PRECAUTIONS AND OTHER IMPORTANT INFORMATION.
INITIAL SETUP PROCEDURE
NOTICE
REFER TO THE INFORMATION INCLUDED WITH THE LOW PRESSURE HVLP GUN FOR SYSTEM SETUP INFORMATION. THE SYSTEM IS INTENDED FOR LOW PRESSURE APPLICATION ONLY.
x Attach air supply hose, gun and low pressure material hose.
x Install the connector to the air supply hose.
x Attach (30) ground kit to ground tab, securing with (25) screw and
(26) nut.
x Attach the ground wire to a suitable ground.
x The gun air supply hose must be 5/16” i.d. minimum.
x Keep containers covered to prevent contamination.
x When using an agitator, install a “T” at the air inlet or use a sepa-
rate air supply source.
Nominal system settings:
x Pump Outlet Material Pressure - 15 p.s.i. maximum.
x Spray Gun Air Pressure - 60 p.s.i. maximum. Note: At 30 p.s.i.
nominal setting it will deliver approximately 8 p.s.i. at the air cap
when using 5/16” i.d. x 15’ long air hose.
x Set air pressure to the pump at approximately 2x (two times) the
operating material pressure.
For example: If 15 p.s.i. material pressure is required, adjust the
pump air regulator / gauge pressure to approximately 30 p.s.i.
Use the material pressure regulator to adjust. Control the spray
gun air volume using the air regulator.
START-UP
1. Turn the knob on the air regulator counterclockwise to zero p.s.i.
2. Place pump and cover (with gun and hose attached) onto the container of material.
3. The operating pressure should be set at the lowest needed to atomize and deliver the paint. Start with the gun material pressure about
the same as the air supply and adjust up or down to set the pattern.
4. Start the pump to cycle by turning the air regulator knob clockwise.
The pump will cycle several strokes until pressure is built up in the
system, at which time it will stop. Check for any loose fittings or leakage.
