High-Precision Volumetric Piston Fillers (Single Station to 12 Station)

Filling Equipment Company, Inc. engineers and manufactures heavy-duty industrial piston filling machines specifically designed for low to ultra-high viscosity products, heavy creams, food pastes, gels, and formulations with suspended solid particulates. Built in the USA with 316 Stainless Steel contact hardware, our piston fillers deliver repeatable volumetric accuracy (±0.5%), minimal product waste, and multi-shift durability for worldwide manufacturing operations.

Single Station Piston Filler with Integrated Hopper

Designed for entry-level, pilot-scale, and semi-automatic production environments. This versatile piston filler operates via a foot-switch trigger or can be effortlessly automated using an optional programmable logic controller (PLC). Configurable with either a straight-down non-drip nozzle or a pneumatically operated positive shut-off nozzle to guarantee zero dripping between fill cycles.

Technical Specifications:
  • Drive Options: Heavy-duty Electric Drive or Pneumatic Drive with Foot Switch pedal
  • Sanitary Build: 316 Stainless Steel product contact parts & 304 Stainless Steel frame
  • Hopper Capacity: Standard 7-Gallon conical feed hopper
  • Volume Flexibility: 5 Interchangeable cylinder sizes up to 136 oz. (4,000 ml) shot volume
  • Valve System: Pneumatically operated Rotary Valve or Sanitary Ball Check Valve
  • Automation Upgrade: Optional PLC control kit for seamless line integration

Why Global Manufacturers Choose Our Piston Fillers

Maximum Viscosity Versatility

Capable of handling extreme fluid ranges — from thin aqueous fluids to heavy pastes, thick greases, peanut butter, and sauces with solid particulates up to 1/2 inch.

Grade 316 Stainless Steel

All contact components comply strictly with FDA food and chemical hygiene standards, exhibiting high resistance to corrosive chemicals, pitting, and intense CIP washdowns.

Rotary vs. Ball Check Valves

Offers custom valve configurations: Sanitary Ball Check Valves for free-flowing, low-viscosity fluids and Pneumatic Rotary Valves for dense pastes and particulate liquids.

Zero-Drip Precision Dosing

Positive pneumatic shut-off nozzles combined with anti-drip suck-back technology prevent product loss, maintaining clean container threads and immaculate packaging lines.

Frequently Asked Questions

Q: What is the primary advantage of a piston filler over a gravity or piston-overflow filler?

A: Piston fillers offer superior volumetric accuracy when handling thick, viscous, or semi-solid products. Because a mechanical piston draws a exact volume into a precision-honed cylinder and forces it into the container, viscosity changes do not affect filling accuracy.

Q: Can your piston filling machines handle food products with solid particles?

A: Yes. When equipped with our pneumatically driven rotary valves and wide-bore stainless steel nozzles, our piston fillers easily dispense salsa, fruit preserves, salad dressings, and chili pastes containing large particulates without crushing the solids or clogging the valve body.

Q: Are Filling Equipment Company piston fillers compliant with sanitary standards?

A: Absolute compliance is guaranteed. Every filler is constructed with 316 Stainless Steel fluid contact parts and FDA-approved seal materials. Components feature tool-less quick-disassembly clamps for fast clean-in-place (CIP) or manual sanitization procedures.
