Product Trouble-Shooting & Application Questions

Q. What could cause a distorted spray pattern?

A. What are the causes and remedies for a distorted spray pattern when spraying with airless equipment?

  1. Pattern surging could be caused by a plugged or excessively worn tip. Clean or replace with a new tip.
  2. Pulsating fluid delivery could be the result of using too large of a tip for the sprayer or using an excessively worn tip. Change to a smaller tip or replace worn tip with a like size new tip.
  3. A shrinking spray pattern could be caused by restricted filters or screens. Remove and clean or replace all filters and inlet screen in the system. Filters can be located in the gun, pump manifold and on the suction tube.
  4. If too many guns or too large of tips are used the pump may not have the capacity to support them. Reduce tip size or the number of guns as needed.

Q. Why do I get streaks in my spray pattern?

A. Streaks in the spray pattern, especially heavy bands at the outside edge, is an indication of low pressure at the tip. Turn up the pressure control knob until these bands are eliminated. If the sprayer is already at a maximum, you may have to use larger diameter hose or shorten the length of the hose to reduce the pressure drop. Also, make sure any paint filters in the system are clean, because there will be a pressure drop across a restricted or plugged screen.

Sprayers are rated for a maximum tip size. Using a tip that is larger than the recommended maximum size or a tip that is worn larger will cause low pressure. The tip should also be the proper size for the type of material being sprayed.

Q. Is there a tool to help properly size a pump?

A. Yes. Use our pressure loss calculator tool to help determine how big of a pump you will need at the beginning of the run to get the pressure and flow rate that you will need at the dispense point.

  • The following key pieces of information are needed to help calculate fluid flow rate:
    1. Fluid pressure at the dispense point
    2. Dispense point orifice size or tip size (if used)
    3. Fluid Specific Gravity or weight / gallon
  • The following key pieces of information are needed to help calculate the friction loss in the line:
    1. Fluid flow rate
    2. Hose / Pipe length
    3. Hose / Pipe inside diameter (ID)
    4. Fluid Viscosity in Centipoise (CPS)
    5. Fluid Specific Gravity
    6. Vertical Rise (if applicable)
