Material: Carbon or stainless steel construction, all wetted parts use 316 stainless steel



Add to Comparison


This basic semi-automatic pail filling machine was designed for top and sub-surface pail filling for 1 to 7 gallon containers up to 19″ tall. The machine will typically use from 3/4″ dia. up to a 1.9” diameter lance depending on the bung opening of the containers.

The application shown above is a free-running, push-along system with five components;

  • Gravity roller infeed accumulation conveyor
  • Model PF-510 semi-automatic, top and sub-surface pail filler
  • Gravity roller conveyor on the scale
  • Gravity roller conveyor after the filler for a lid and label station
  • Gravity roller discharge accumulation conveyor

Description of Operation

This is a model PF-510 top and a sub-surface filling machine.


  • Empty containers are placed onto the infeed conveyor to accumulate
  • The operator pulls a container onto the filling station and presses start
  • The lance will insert to the bottom of the container, if sub-surface filling
  • The controller will zero the tare weight before the fill cycle begins
  • When the fill cycle is complete, the lance will rise to its home position
  • A pneumatic drip pan will move into place to catch any residue
  • The operator will move the filled container to the lid station
  • Another empty pail will be pulled onto the scale conveyor

Liquid Filling Equipment Options

Concept Drawing

A straight-line configuration is the most common for a pail filling system. This includes pail accumulation before the filler, one pail at the filler and another pail at the bung and label station. The amount of accumulation and length of conveyors are determined by the customer.
