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 sys-
tems. These systems generally operate using low material pressure
(less than 30 p.s.i.), and when complimented with the proper gun, it pro-
duces 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 di-
aphragms and is designed to be used with waterborne paints. The gun
and low pressure air and material hoses are not included. (Continued)
