GP Series Piston Fillers are non-electric piston fillers for use in wet environments. Designed for both safety and convenience, these paste and cream fillers can be set up and operated anyplace where electricity is not available or where there may be a safety concern. Ideal for handling chemical and flammable materials, these piston fillers use a foot pedal to trigger the fill cycle. We carry electricity-free liquid, cream and paste fillers that can handle up to 1,000 milliliters of product at Cleveland Equipment.
