Pump Filling Machines

Pump fillers use a dedicated pump per fill head to move product from a supply source into the container. Different pump technologies suit different products: peristaltic pumps for sterile or shear-sensitive liquids, gear pumps for thicker products and lobe pumps for products with soft particulates. They are common in chemical, cosmetics and specialty food operations.

How it works

Pump filling machines use a mechanical pump, such as a gear, lobe, peristaltic, or diaphragm pump, to move product from a supply source through a metering system and into the container. The pump type is generally selected based on product viscosity, shear sensitivity, and whether particulates are present. Fill volume is controlled by pump speed, rotation count, or timed operation.

Common applications

• Filling a wide range of liquid viscosities
• Dispensing shear-sensitive formulations with peristaltic pumps
• Packaging chemical and industrial fluids
• Transferring and filling viscous food products

Typical products and containers

Advantages

• Adaptable to a broad viscosity range depending on pump type
• Can handle continuous or intermittent flow needs
• Some pump types allow gentle handling of shear-sensitive products
• Often supports inline blending or additive dosing

Buying considerations

• Match the pump type to your product's viscosity and shear sensitivity.
• Confirm wetted parts are chemically compatible with the product.
• Consider whether the product contains particulates that could affect pump wear.
• Evaluate cleaning and sanitation needs, especially for food or pharmaceutical use.
• Check that the pump's flow range matches your target fill volumes and speeds.
