Coloured and protected surfaces provide added value as paints and enamels help to make products both more interesting and increase their life. That is why they are important finishing materials where care, environmentally-friendliness and reliability are needed in their supply and correct dosage.

The DESMI ROTAN® gear pumps are commonly used for paints, resins and coatings. For ink manufacturing and printing press applications, the HD series and specially fitted PD and ED magdrive pumps are being used.

A leading paint factory manager, states:
“ROTAN® pumps have for decades been used in numerous of our plants. The ED model was chosen due to its magnetic coupling. A magnetically coupled design, which has no rotating seals, ensures less downtime and lower operating costs. Every pump in our new facility is magnetically coupled, and thus we have eliminated the problems associated with packed glands and mechanical seals.”

Production stops are the most costly activity the industry has. That is why companies all over the world rely on high quality pumps like DESMI ROTAN®.

 

Dark, milk or white chocolate

Pumping products like jam, dissolved sugar, dark, milk or white chocolate with whole nuts or other ingredients, DESMI can provide the solution to transport various liquids.

Being one of the leading chocolate pump manufactures, we have a variety of pumping options to suit the needs of the chocolate industry.

The product itself, application know-how and most importantly customer understanding, relationship and production demands are our leading stars when selecting the best solution for our customers.

The ROTAN® pumps from DESMI are designed for pumping media with high viscosity such as chocolate, cocoa mass, cocoa liquor, cocoa butter, liquid chocolate, dissolved sugar, caramel, and other sugar products. The pumps are equipped with a heating jacket on the front and rear end. Rotors, idlers and idler bushings are with special clearances, enabling working pressures up to 12 bar.

Half a century of experience in the production of pumps for the chocolate industry and close collaboration with some of the leading producers of plants have resulted in unique pumps which meet the high requirements for the careful treatment of chocolate products.

 

Pumping and handling bitumen products

DESMI has a full range of different pumps and matching equipment supporting the handing of bitumen products. Including unique features suited for today’s needs and new polymer based formulations, we have the solution.

For certain applications, we can offer proven sealing options, available is also a patented zero-leakage pump with a state of the art magnetic coupling. This pump offers a total protection against spillage and vapour, which may create environmental hazards. Electrical heating is an alternative to heating by liquid or steam.

Applications tend to fall into four categories: Production (refining), distribution (terminals), hot mix (paving mixtures), and roofing (filled asphalts). Refineries and terminals often use steel pumps, while hot mix asphalt plants use mainly cast iron pumps with heating jacketed, and either packing or mechanical seals. Roofing plants are generally pumping highly abrasive, filled asphalts for shingle manufacturing. These require special hardened parts, slower operating speeds and other means of minimizing wear.

 

Slurries in the pulp & paper industry

For decades DESMI ROTAN® gear pumps have been used throughout the world, successfully pumping a variety of liquids such as sulphate soap, tall oil, pitch fuel/oil, caustic soda, lignin, turpentine, resin, starch, and slurries in the pulp and paper industry.

We have the products, the knowhow and the field experience to be the first choice supplier for positive displacement pump within heavy industry.

Gear pumps are used in high demand applications where a reliable and constant flow is required. High capacity and external lubrication on slide bearings are advantages important for a good process and a reliable pump solution.
