The agitation within a spray tank can be either jet or mechanical. Jet agitation utilizes an area of the pump's output to stir up the fish tank. Mechanical agitation, utilizes paddles (usually of stainless steel) on a shaft that is turned by belts and pulleys relating to the vehicle.

Jet agitation is costly to install and service and is plenty for most applications. Mechanical agitation is the best for mixing heavy granular, or non-soluble, materials can add $500 - $1000 towards the cost of one's pest control spray rig.

Agitation Jets:

The agitation jets must be positioned make sure that the entire tank is agitated with dead spots exist for material to be. When filling the tank be to see the agitation pattern before accepting the rig from your supplier.

Volume:

Jet agitation requires a pump which output volume sufficient about your spray application plus the amount required to agitate the tank.

As a guide of thumb, most liquid materials require 8% of tank volume for irritations. Most granular or non-soluble materials require 12%. In other words, to agitate a 200-gallon tank that you will be mixing a liquid concentrate into, you've to 8% times 200 gallons, or 16 gallons each minute (gpm), for agitation.

Agitation boosters reduce the degree required by creating jet proceeding. Most commonly used boosters are 3X though 5X can also be found. This means that instead of 16 gallons per minute, we need 16 divided by 3 or 0.33 gpm.

You need to select a pump with output of about the desired spray volume plus the mandatory agitation bloatedness. If you need to spray at 5 gpm, you need a pump will certainly provide up to 10.33 gpm (5 gallons for spray plus couple of.33 for agitation). You will actually want a pump permit anyone do more output than is needed because the rated output is for a new pump with no restrictions, actual output will almost allways be lower.

Plumbing:

Some equipment providers plumb the agitation on the pump roi. We strongly believe this can be a bad hint. Pump manufacturers - Hypro, Udor - specifically warn against this as it can create back pressure that make a difference to the pumps performance. This is often a bad idea because return lines cannot have disconnect valves in them. And since you cannot shut there are various line, if for example the pump requires service once the tank is full, enjoyment to dump the equipment. However, centrifugal pumps are the exception for this.

We recommend separate lines with the return to # 1 of the tank and also the agitation into the bottom. Also, it is helpful to place a gate valve close to agitation line so that the agitation can be adjusted. This is also an good way to adjust the stress of your spray line. More agitation means less pressure on the spray line.
