Fillflex-Matningssystem_1

Fillflex™ Feed System

When filling viscous products, the filling machine’s pump is sometimes unable to draw the product from the storage tank or mixing tank. In this case, it is a good idea to use a product hopper as a buffer tank and a feed pump that maintains a constant level in the hopper, with the aid of a sensor. This solution also provides significant benefits when it comes to precise dosing, as the product level is continuously held to keep an even inlet pressure to the filling machine’s pump.

The control cabinet for the feed pump contains a frequency control and is a separate unit as standard, but can also be integrated in a larger controller cabinet that also houses the control for the filling machine.

In most cases, the level is controlled by an ultrasonic sensor, which is mounted in the product hopper’s cover. Some liquids may require alternative sensors, however, which can also be offered in such cases.

All the pumps in our range can be used as feed pumps, although in that case they are not equipped with rotary encoders for dosing.

As an option, there is a suitable trolley that turns the feed pump into a complete mobile device. Suitable suction and product line feed kits can be found in the Accessories section.

  • Minimises problems associated with feeding
    product to the dosing pump
  • Maintains a constant level in the product hopper
    for the dosing pump, which contributes to higher
    filling accuracy
  • Reduces start-up problems associated with air in
    product inlets to the filling machine
