There is a total of four spray bars on the SW Series
rollers. Two spray bars on the front drum and two spray
bars on the rear drum. Each spray bar has one water
pump dedicated to it, for a total of four water pumps, one
for each spray bar. When pump 1 is selected for either
the front or rear drum, one spray bar is operational. When
pump 2 is selected for either the front or rear drum, the
second spray bar is operational. When “ Both ” is selected
for either the front or rear drum, both spray bars operate,
providing double the volume of water going to wet the
drum. In most cases, only pump 1 or pump 2 is selected.
In a few situations, where a heavy application of water is required on the drum, such as in
very windy and/or dry desert conditions, both pumps are used simultaneously.
When only one pump is required, it is recommended to alternate pumps so that they both
wear evenly. Alternating pump use also helps to keep them in better operating condition by
running water through them to keep the inside of the pump wet. For example, on a multi-day
project, it is recommended to use pump 1 on the first day, pump 2 on the second day, and
alternate each day.
