Description

What does make the Pneumatic Level Controllers different?

The ingenious system of the Pneumatic Level Controllers is operated with pneumatic components only. The level control system may be installed in sumps, tanks or tubs to start and stop the pump at certain liquid levels (automatic with TPUK-LA or manual with TPUK-LM). This system is allowed for use also in explosion hazardous areas, thanks to the absence of electricity.

The panel is 200 x 200 x 130 mm and is available for all Tapflo AODD pumps and can be supplied in either ABS Plastic (IP55 or 65) and Stainless Steel AISI 316 (IP44).

TPUK-LA – Automatic Evacuating / Filling of Vessels or Sumps

TPUK-LA – Automatic Evacuating Filling of Vessels or SumpsThe level controller utilizes low-pressure air passed through dip tubes to detect liquid levels. The system controls the liquid level between the dip tubes and can be configured in either ’filling’ or ’emptying’ modes.

The end of the hose “low” (E) (or end of extension pipe) is placed on the desired low level in the sump and the end of the hose “high” (F) is placed on the high level position. As the liquid is reaching the high level hose, the pump will either start or stop and pump until the desired liquid level is reached. It is a very accurate system, sensing the levels within a few millimetres.

TPUK-LM – Manual Filling / Evacuating of Vessels or Sumps

TPUK-LM – Manual Filling / Evacuating of Vessels or Sumps

The system is manually started and the AODD pump begins pumping emptying or filling the vessel or sump. The pump is then automatically stopped when the liquid surface is detected at the dip tube.
