Chapin Backpack Sprayer

Yes, this model is equipped with Viton seals, which are specifically designed to resist degradation from harsh chemicals, herbicides, and insecticides.

The empty unit weighs 10.25 pounds. Since it has a 4-gallon capacity, you should expect the total weight to be roughly 43 to 45 pounds when filled with water, depending on the density of your solution.

The internal pump cylinder is engineered for efficiency, meaning it requires less physical force to build and maintain pressure than standard external pump designs. The padded shoulder straps also help distribute the weight to make the operation feel more manageable.

The sprayer features a built-in filter designed to catch debris before it enters the system. However, if you are using powders or homemade solutions, it is always best practice to strain your mixture before filling the tank to ensure the filter doesn't get overwhelmed.

Yes, the tank is designed with a translucent material that allows you to easily monitor fluid levels at a glance without having to open the lid.
