Plastic magnet-drev centrifugalpumper

Metal efterbehandling og pletteringsprocesser, er anerkendt som værende blandt de mest udfordrende applikationer til pumper. Dette er ofte som et resultat af det miljø, som de pumper er i drift, sammen med den brede vifte af aggressive væsker, der anvendes i mange af disse overfladebehandling og efterbehandling processer. Den Finish Thompson sortiment af plast magnet-drev centrifugalpumper tilgængelige via MICHAEL SMITH Engineers, har været anvendt med succes i nogle af de mest krævende metalfinish applikationer.

One interesting example is Wright McGill, manufacturers of the Eagle Claw Fishing Tackle brand, a Colorado based company who use Finish Thompson DB Series pumps. The company produce millions of high quality fishhooks every year in a myriad of styles and colours which requires an incredibly efficient range of precision metal finishing processes. These processes include nickel, electroless nickel (EN), tin, brass, zinc, bronze, and even gold plating. The hooks are manufactured in so many colours because specific colours have been found to be attractive to certain species of fish. In addition to plating, their metal finishing processes also include washing, heat-treating and the application of various paint type coatings.

I 2005 blev Finish Thompson færdiggøre udformningen af ​​deres nyeste magnetiske drev pumpe, DB-serien, som bød manipuleret plast og andre specialiserede materialer for at sikre optimal korrosionsbestandighed.

As well as using these materials they benefitted from the latest engineering technology including computational fluid dynamics, finite element analysis and custom magnetic design software.
Til at færdiggøre udviklingen og testprocessen Finish Thompson havde brug for en passende krævende test site og Eagle Claw produktionssted var glad for at forpligte. En af de involverede koncentreret salpetersyre, der anvendes som stripningsmiddel bebyggede plating materialer på tønder og andre genstande, der anvendes i deres pletteringsprocesser, at fjerne processer. Salpetersyre er en meget aggressiv stærkt oxiderende syre stand til at opløse de fleste metaller og har en alvorlig effekt på mange andre materialer. Til sidst, salpetersyre blev mættet med de forskellige plating produkter fjernet under stripningsprocessen og ingeniører begyndte at se på mulighederne for at reducere brugen af ​​salpetersyre. Dette førte til installation af DB serien pumpen på en sti basis i et filtersystem, som var designet til at genbruge det salpetersyre.

A DB test pump was manufactured from extremely corrosion resistant materials including precision moulded carbon fibre filled PVDF, PTFE bushing, high purity ceramic and powerful neodymium drive magnets encapsulated in pure PVDF. It was then installed in the nitric acid recycling system, a truly challenging application. Once installed on the filtration system it was used to circulate approximately 680 litres of nitric acid through a series of filters with each filter removing progressively smaller particles. The goal was to re-circulate the tank about three times per hour until the nitric acid was clean enough for reuse. The pump was in regular operation for six months while the effectiveness of the filtration process was evaluated. Due to the excellent performance and reliability of the pump in that test, Wright McGill continues to use Finish Thompson magnetic drive pumps for handling corrosive and hazardous fluids in applications throughout its facility.

As a result of the non-metallic materials used for both the housing and all the key wetted components, DB pumps are ideal for transferring corrosive liquids in chemical manufacturing, metal plating, surface treatment, wastewater treatment, electronics manufacture or wherever hazardous liquids need to be pumped safely.
De fås i et tæt koblede design konfiguration for magnet tilpasning optimal og give forlænget tør-køreevnen når den er specificeret med en carbon bøsning og er derfor beskyttet mod systemets forstyrrelser.

Other features and benefits include; high operating efficiency resulting in lower energy consumption, improved hydraulic coverage for both 50 and 60 Hz operation. They have evenly spaced impeller trims enabling duty points to be precisely met and a two-piece impeller design which allows the impeller or inner drive magnet to be individually replaced. Also, the DB Series pumps offer high working pressure capability which means fluids with a high specific gravity can be easily pumped without the need for impeller trimming.
Pumperne er konstrueret til enten vandret eller lodret installation (vertikal, når de er udstyret med en IEC-motor), de har en maksimal driftstemperatur på 180 ° F (82 ° C) for polypropylenmodellen og 220 ° F (104 ° C) til PVDF mulighed.
