Ammonia is currently at focus as clean alternative to heavy fuel oil that has predominantly been used. The technology employed in order to use liquid ammonia as a fuel must be hermetically tight and guarantee maximum operational safety as the gas is toxic and harmful to the environment. LEWA’s high-pressure diaphragm pumps meet these requirements. Their standard safety mechanisms make them suitable for hazardous, toxic and environmentally harmful fluids such as NH3, even under extreme operating conditions.

In March of 2023, CO₂ has been stored underground for the first time worldwide, and on a transnational basis, within the scope of project “Greensand” to counteract the effects of climate change. This project demonstrates how CO₂ emission sources can be combined with suitable CO₂ storage areas.

Using canned motor technology for submersible pumps provides significant advantages. A short shaft, only two slide bearings – independent from the immersion depth – and various monitoring functions not only ensure high reliability but also mean cost advantages for the operator. Since it is supplied as a lock pump, easy servicing is guaranteed at the same time.

The Italian company Lavazza relies exclusively on a CO2 extraction method to remove caffein from coffee beans. The process makes use of high-pressure CO2 in a supercritical state. Due to its high compressibility, the supercritical aggregate state of CO2 poses a challenge for process stability.

Whether providing process heat or fulfilling the pumping process – in numerous industrial and technical processes, the pump technology used must cope with extremely high temperatures and the high pressures that often accompany them.

With a competition length of 1,615 metres and 16 curves, the so-called “National Sliding Centre” is the largest artificially-iced bobsleigh, luge and skeleton track in the world. It was built for the 2022 Winter Olympics near Beijing and is located not far from the Great Wall of China. The combined track for bobsleigh, skeleton and luge will accommodate 10,000 visitors.

HERMETIC-Pumpen GmbH develops canned motor pumps for diesel fuel desulphurisation units. HERMETIC supplied a canned motor pump with a flow rate of 1,000 m³/h and a delivery head of 65 m for of a Chinese refinery.

The sales market for plasticizers is enormous. In 2018, their global volume was 7.6 million metric tons according to the Ceresena Research market research institute – and the trend is steadily rising.

Pump specialist from Gundelfingen supplies canned motor pumps for plastics production – over 350 HERMETIC pumps for polyethene production have now been installed.

HERMETIC-Pumpen has further expanded its modular product line “V-Line” for the chemical and petrochemical industries.
