Vacuum Technology
Steam jet liquid pumps
Steam jet liquid pumps are based on proven jet pump technology and often used to elevate and convey liquids.
Aplications
Elevating and conveying of liquid chemicals such as lye, acids, tanning liquors, lime milk, effluent water, spent wash, mash, bilge water, etc.
Circulating with simultaneous heating of the liquid contents.
Mode of operation
The three main components of steam jet liquid pumps are head, diffuser and motive nozzle. The steam jet emerging from the motive nozzle at high velocity transmits its kinetic energy to the liquid, mixes with it and condenses. In this way, the liquid is conveyed and its pressure is increased at the same time.
These pumps operate like a steam jet vacuum pump and evacuate the suction pipelines. They are, therefore, self-priming.
In compliance with the varying demands, two different classes of standard steam liquid pumps are constructed:
- CLASS A: for low suction heights, up to max. 1 m (where, density, ρ = 1000 kg/m³ or liquid feed) and large discharge pressures
- CLASS B: for larger suction heights and discharge pressures up to approx. 1.1 bar g
In addition to the standard pumps, we supply special constructions for larger suction heights and discharge pressures.
Advantages
- Simple erection and servicing
- No moving parts, therefore, no wear
- Maintenance-free
- Great reliability and safety of operation
- Long life
- Low cost

A new recipe for indulgence
What if your favorite chocolate didn’t require cocoa beans and your coffee was locally produced? As climate disruption, price hikes and ethical concerns hit two of our most beloved indulgences, scientists are reimagining how we produce them – using microbes, not monocultures. The goal: preserve the flavor and properties of coffee and chocolate while minimizing carbon emissions and improving food resilience.
Fueling the circular economy in shipping
Ports now compete not just on logistics, but on sustainability. At Greece’s Piraeus port, an advanced processing and recovery facility recycles ship waste oil into fuel. Equipped with GEA’s high-performance centrifuges, it sets a new benchmark for state-of-the-art, environmentally responsible port operations.
