Construction features: High-precision, electrically driven ball screw movement, faster and more precise than pneumatic or air over oil systems. Fill and charge speeds can be better controlled and changes performed at any point of the stroke (i.e., to reduce speed at the end of a fill cycle to avoid splashing). Capable of handling breakable particles up to ¾ in diameter. Reservoir tank mounted directly above rotary valves for direct product feed. Heavy duty 304 stainless steel welded frame construction. PET rotary valves. Minimal air consumption. All contact parts are stainless steel, sanitary, Teflon, Buna, Viton. Omron PLC for all machine logic functions.
