Gather: From laboratory to production via pilot plant

Tuesday, April 4th, 2017 von admin

A process generally undergoes initial development within a laboratory and is then made production ready in pilot or mini plants. During this scale-up, a range of different problems can emerge, e.g., in the way temperatures behave. In a laboratory, a process may be endothermic but becomes exothermic in production. How pumps behave in relation to peripheral equipment can change under full-scale production conditions, Sven Borghoff describes a coordinated pump and drive concept which makes scaling up easier.

Dosing pumps with multifunctional extensions for different pump types often used in laboratories generally have no particularly high temperature or pumping ranges. However, when scaling up, these aspects take on major significance. Gather uses its magnetic-driven pumps (Fig. 1) here. They are available in such a broad range that when scaling up from the laboratory to production via a mini or pilot plant, the pumping and control technology can be retained. The company cooperates with the chemical industry, institutes and universities to make process development from initial laboratory trials through to production easier.

Quattroflow: Hygienic pump for accurate flow and wide flow range

Friday, September 16th, 2016 von admin

quattrotecThe target application for this positive displacement quaternary diaphragm pump series is the continuous dosing of high-value additives in the food and beverage and personal care industries (e.g. to add concentrates to a fluid stream for soft drinks) as well as for in-line dilution. These ‘QuattroTec’ called pumps can provide a consistent flow that results in a constant and continuous dosing of ingredients in hygienic processes.

Fristam adds double-screw technology to its pump portfolio

Thursday, May 12th, 2016 von admin

FDS_mit_FoerderschraubenThe pump casing of Fristam FDS pumps comes in three parts, consisting of an intermediate flange, the screw casing and the pump cover. This enables individual adaptation of the connections to any conceivable production system requirement. Thanks to central positioning of the gearwheels inside the bearing support area, the entire pump comes in a very compact design. Moreover, its massive shaft has reinforcements in the area of critical diameters to ensure maximum rigidity. Further stability is achieved through a combination of particular large bearings and an increased bearing distance. The result is smooth running with minimal wear.

Lewa: New plunger pump according to API 674

Wednesday, April 16th, 2014 von admin

QuintuplexThis new generation of pumps has splitted gear housings. This special feature significantly facilitates maintenance, permitting the use of a fully balanced crankshaft which generates less noise and vibration, thus reducing wear. The power range was also extended with two quintuplex plunger pumps.  The very short design of these plunger pumps is made possible by the special alignment of the plunger and crosshead. These pumps also have high efficiency, low energy consumption, and a long service life.

Mouvex: Eccentric Disc Pumps for Isocyanates

Saturday, February 2nd, 2013 von admin

Mouvex_SLC-Series

Isocyanates require a pump that handles product gently (low shearing), has strong suction capability, and offers a low-maintenance wear-compensation design. The SLC Series Eccentric Disc Pump features superior suction at low speeds, ensuring minimum product is left in the piping prior to maintenance. The design of the SLC Series allows the pump to self-compensate for mechanical wear, giving the eccentric disc pump the ability to maintain consistent flow rates over time.

Almatec: Single-Use Biologic Pumps

Wednesday, January 16th, 2013 von admin

This single-use line of pumps – named Quattroflow – is developed for use in biologic-handling applications within pharmaceutical and biotech operations. The incorporation of single-use pumps in biologic-handling applications is gaining wider acceptance among pharmaceutical and biotech manufacturers because they can help optimize end-product speed-to-market. Single-use, or disposable, pumps feature replaceable wetted pump chamber, which is an advantage for manufacturers looking to maximize their production operations. The single-use pumps reduce downtime between two batches, save time and money, and are quick and easy to change.
