Quattroflow Releases New Multiple-Use Pump for Biopharma Applications

For applications in process technology with medium hydraulic outputs, the question often arises as to whether the pulsation of an oscillating pump with only one plunger is too high. It is not uncommon for a less expensive single-head pump to be used in this transitional area.

In 2021, around 11 billion tons of cargo were transported by sea worldwide. This accounts for almost 90 percent of global trade and means that the shipping industry, which has mainly been powered by heavy fuel oil until now, is responsible for around three percent of global CO2 emissions.

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.

At this year’s Anuga FoodTec, pump manufacturer LEWA will be presenting its newly developed LEWA homogenizer test system, that can be used to test the aseptic functioning of a homogenizer based on a hygienic hermetic process diaphragm pump. Thanks to a homogenizing valve that is also hygienic, it can be flexibly adjusted to the requirements of different emulsions.

Xylem’s Flojet brand has enhanced its innovative VersiJet Series industrial motor driven diaphragm (MDD) pumps with the introduction of a new, four-chamber model. Leveraging market-leading pump technology from Flojet, the new MDD pump has been specifically designed to serve industrial applications requiring flow rates of between 3 and 5 gallons per minutes (GPM), the equivalent of approximately 11 to 19 liters per minute (LPM).

Polymers play a key role at municipal/industrial water and wastewater treatment plants, but also bring the risk of major disruption and extra expense if they are not handled with reliable, leak-free equipment. A polymer leak can halt production and be costly, time-consuming and labor-intensive to clean up, and also creates a safety risk.
