Liquid ring technology

The words in themselves give it away. It is a technology that works by means of a liquid ring, typically water. With the liquid ring technology, you have no contact between the pump shell and the rotor inside. The liquid ring is the sealant between the suction and the pressure side of the liquid ring pump. Using liquid ring technology, in vacuum pumps, gives you a consistently great performing vacuum source. With no harmful emissions during operations. It is cost effective, requires less maintenance and service.

Working principles

The pump is filled up with liquid, typically water, to approx. half of the housing volume. The rotor starts spinning and the centrifugal force pushes the liquid towards the housing wall. And you get the liquid ring. The liquid ring and the rotor cells create a piston pump effect, and you get the suction and pressure effect.

What are liquid ring pumps used for?

Liquid ring vacuum pumps are installed as a crucial component on vacuum trucks. On vacuum trucks the liquid ring pumps are doing a lot of different jobs such as. Emptying individual households’ septic tanks, keeping underground infrastructure clean in cities and handling wet waste from all kinds of industries.

Moving liquids and fluids

Liquid ring pumps are useful for managing liquids and semi-solid wastes. Essential for cleaning out different liquid waste systems and environmental cleanup efforts.

Also cleaning and maintaining vessels, pits, tanks and silos, collection of various kinds of waste f.x: grease trap, oily water, sludge, contaminated water, stormwater, and drill water.

Sewer and industrial cleaning

From managing dry bulk materials to handling hazardous waste. The versatility of the liquid ring pumps come into play across multiple industries.

Sewer and industrial cleaning covers handling hazardous materials, waste removal from industrial facilities, and even managing materials in mining operations. The pumps are used for cleaning sewer lines, catch basins, and storm drains.

Excavation jobs

Digging through the ground while ensuring minimum damage to the surrounding areas. The strong suction power of the liquid ring pumps are making them very useful in sensitive excavation tasks.

Specialized applications such as uncovering and exposing underground utilities and pipelines and digging narrow trenches also here the robustness of liquid ring pumps is utilized.
