Open the catalog to page 3A Quality-Conscious International Partner DESMI, formerly known as A/S De Smithske, was founded in 1834 Over the years the product range has developed concurrently with the market requirements. From foundry products such as stoves and church bells to steam engines and pumping plants and over to steel constructions like bridges, tank installations, and cranes. DESMI is owned by a group of DESMI executives. DESMI pumps are marketed and distributed by subsidiaries, sales agencies, and distributors in more than 40 countries.

Open the catalog to page 4ROTAN®, One of the world’s Leading pumps within Internal Gear Pumps The internal gear pump principle was developed in 1915 by a Danish American. In 1921, he licensed a Danish company to manufacture the pumps, which have been continuously marketed worldwide under the ROTAN® name. The unique, modular concept of ROTAN® pumps is generally recognized as the most advanced internal gear pump design available today. The ROTAN® internal gear pump provides favourable flow conditions, as the direction of the liquid flow is only changed slightly through the pump. Method of operation Liquid inlet Liquid...
Open the catalog to page 5ROTAN® GP – General Purpose Pumps Pumps in cast iron, for clean, non-abrasive liquids. The simple and compact construction makes it a low-cost pump, often used in modified versions by OEM customers. A close-coupled OEM model is also available GP pumps are designed for use with IEC or NEMA flange motors. Available with 90° angular configuration. Pumping of: Capacity Range Speed Differential Pressure Suction Lift Up to 0,5 / 7.25 psi bar vacuum while priming Up to 0,8 bar / 11.6 psi vacuum while pumping Viscosity Range Clean oil Glycol Vegetable oil Solvents Lube oil Waste oil Fish oil ROTAN®...
Open the catalog to page 6Capacity Range PD pumps are designed for refinery and petrochemical applications, all pressure-containing components are in carbon steel. PD pumps meet API 676 standards with only a few exceptions. Available with 90° angular configurations. Additives Bitumen Polystyrene Wax • Fuel • Oil • Gasoline • Lube oil • Grease • Other hydrocarbon based fluids Pumps in stainless steel, designed to handle corrosive liquids. CD pumps are designed for handling corrosive liquids, primarily found in the chemical processing, food and pharmaceutical industries. Available with 90° angular configuration....
Open the catalog to page 7ROTAN® ED – Environmental Duty Pumps Magnetically coupled pumps for ultimate protection against leakage. As only minimal maintenance is necessary, ED pumps will be a very economical solution compared with traditionally sealed pumps, especially where the application requires the use of double mechanical shaft seals. Often these applications are very different, resulting in the seals and support system requiring regular attention and/or replacement. Thus, the life cycle costs for ED pumps are generally much lower than for pumps using two seals. Where no leakage, liquid or gaseous, is allowed....
Open the catalog to page 8One of the distinguished features of the ROTAN® ED range is that the pumped medium is hermetically contained in the system since the magnetic coupling eliminates the need for a shaft and mechanical seal, which could allow gaseous exchange between the pumped medium and the atmosphere. Unlike centrifugal pumps, the ROTAN® ED pump offers gentle liquid handling and a high priming vacuum as well as the pumping of highly viscous liquids. • Dynamic axial balancing system, minimizing axial loads, saving energy and increasing life (see picture on the left side) • Patented cooling system, based on an...

Open the catalog to page 11To comply with increasing requirements for pumps in areas with no space for normal horizontal configuration, a new vertical design has been developed. Vertical design advantages: • Easier servicing - dismantling the whole rear end including bracket, rear cover, rotor and shaft without moving neither pump casing nor motor/gear. Enough space for dismantling the rear cover, idler and idler pin, which makes it possible to disassemble the pump completely without removing the pump casing from the pipe system. GP/HD/CD/PD pumps are available in vertical design. To meet the increasing demands the...
Open the catalog to page 12Chocolate Pump A speciality within the ROTAN® range is the ROTAN® chocolate pump for pumping cocoa mass and chocolate. This special configuration has been utilized in the HD and CD ranges with all its advantages: • Casing available as inline (standard) or 90° angular configuration (BCHD). • Specially designed externally lubricated main bearing. • Configuration with special clearances between the fixed and the rotating parts to protect the chocolate from excessive temperatures. Electrical Heating ROTAN® has for many years supplied pumps to the asphalt industry, and being a pump manufacturer...
Open the catalog to page 13True back-pull-out feature allows inspection/repair of the rotating cartridge without disturbing the piping or coupling alignment • Reduced downtime costs • Reduced labour costs • Spares optimization ROTAN® pumps are made with a ”back-pull-out” system. This means that a pump, delivered on a base plate with a spacer coupling connecting gear or motor to the pump, can be serviced without breaking any pipe connections or moving the motor/gearbox. Just by taking out the spacer in the coupling you have access to dismantle the total rear end of the pump. Now the ROTAN® Uptime Cartridge can be...
