The 811SP Series extends Griswold’s portfolio of chemical process centrifugal pumps into self-priming applications. The pumps are designed to leverage common components with the Griswold 811 ANSI Series and offer pump and part interchangeability with competitor models.

Different stator materials and a separable rotor assembly add to the advantages of the 1-component dispensing pump from ViscoTec.

The proven M900 pump head is characterized by its hermetic tightness, high metering accuracy, and particularly robust hydraulics. Until now, however, pump heads of this type could be used in the two smallest sizes of the LEWA Ecoflow series only up to 100 and 150 bar, respectively.

Smaller portions and larger margins are the trend among food companies. This implies that a change of the requirements for dosing and filling technology is necessary. The latest product in the Hygienic series in the ViscoTec portfolio, the vipura-PUMP 10T dosing and filling pump, fits in perfectly with this trend.

Watson-Marlow Fluid Technology Group (WMFTG) is unveiling the next performance level in its range of industry-leading Qdos chemical metering pumps. Qdos Conveying Wave Technology (CWT) extends the capabilities of peristaltic pump technology and offers longer service life than traditional tube-based designs.

Reliable pumping of low flow rates at high differential heads is the core competence of SERO PumpSystems, the recognized technology leader of side channel pumps. SERO‘s Model SEMA-S is a sealess, magnetically driven pump designed for the safe conveyance of ammonia and many other volatile process fluids.

Diaphragm pumps work entirely without oil. This makes them ideal for all tasks and numerous applications where a clean, dry vacuum is needed. These include laboratories, analytical systems, leak detection and research & development. With the MVP 030-3 C DC, Pfeiffer Vacuum has now introduced a new corrosive gas version of the diaphragm pump.

Kirloskar Brothers Limited’s pressure boosting Hydro-Pneumatic (HYPN) system is an intelligent water supply solution ideally designed for residential and commercial buildings, hotels, hospitals, and industries that can serve the changing water demand at constant pressure. HYPN system is a conventional pumping system converted into an automated pumping system.

EnviroGear, part of PSG, recently announces that its G Series Internal Gear Pumps are now available with jacketing.

At Emile Egger, a global manufacturer of centrifugal pumps and Iris control valves, products are tailor-made according to customer specifications. A few years ago, the company analyzed its customers’ requirements and then embarked on further developments of RPP/RPG elbow pumps to optimize them for higher flow rates and lower relative differential heads.
