  • ROTAN®- Internal Gear Pumps

  • 适合各个解决方案

    Rotan®internal gear pump provides favourable flow conditions, as the direction of the liquid flow is only changed slightly through the pump.
    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.

        • In South Africa there are many infrastructure projects which require either temporary or semi-permament fuel intallations (usually diesel). DESMI Modular S pumps are used for these installations.

          燃料设施需要:

          • Environmentally friendly
          • Portable
          • Easy to set up

          DESMI distributor in Southern Africa, Pumptec, has had a great deal of success in supplying Modular S pumps for containerized fuel units.

        • Huntsman looking for a better solution

        • Huntsman Holland produces raw materials for the polyurethanes industry. Due to pump problems, the company was looking for a better solution.

          在五个设施中,有许多用于运输各种原材料的泵。机械维护工程师RenéVande Vlugt说,以前使用了机械密封的泵,但实际上是有问题的。“在这种情况下,当这些泵显示出泄漏时,对于环境和人来说,这并不是一个特别大的问题。当与大气接触时,溢出的材料立即变硬了...

          A solution for this problem was found in magnetically coupled pumps from the ROTAN® ED Series.

        • Dan-Balt A/S - Pan European Terminals PLC

        • DESMI NSL centrifugal pumps for heavy fuel oil transfer at the Dan-Balt A/S terminal in Aaberaa, Denmark.

          General Manager Hardy Olsen requested pumps for the transfer of heavy fuel oil and the technical requirements for the future pumps were:

          • 1000 m3/h at 7.5 bar
          • 0.990 kg/l
          • 400 CST - 60oc

          DESMI’s solution was three DESMI NSL 200-415 inline centrifugal pumps with 200 kW 4-pole motors incl. frequency converters for more flexibility.

        • DESMI ROTAN®Pump in ABS Application

        • The pumping liquid is ABS, Acrylonitrile-Butadiene-Styrene, a type of rubber solution widely used in the tire industry with low energy consumption, low noise and lighter weight.

          对于该项目,两个泵是处理培养基“橡胶溶剂+聚苯乙烯+HCN” -CDEXXM -3U332,并且由于HCN是一种非常有毒的介质,我们为这两个泵提供双api52齐平。其余七个泵处理矿物油,是我们的标准不锈钢和铸铁泵。在这一阶段项目之后,Huayi将启动另一个更大的ABS项目,因此毫无疑问,这是DesmiRotan®的战略项目。

        • Magnetic Driven Pumps in Molten Sulphur Service

        • Pumping Molten Sulphur is most challenging. Sulphur temperatures must be controlled within a 120-155o C range. Outside this temperature sulphur solidifies.

          Sulphur has a distinct odour and is highly corrosive in the presence of moisture. Where leakage from common packed style pumps was unacceptable, a ROTAN® magnetically driven pump unit was offered on a trial basis where the chemical is used in the production of soap and shampoo.

          1998年夏天 - 欧洲领先的油漆和漆生生产商之一S. Dyrup&Co。为制造溶剂的油漆和木材防护剂安装了先进的工厂。
        • Polyurethane Foam/Isocyanate

        • Through the ages all kinds of seals have been used, from soft shaft seals to double mechanical shaft seals with DOP (dioctylphthalate) or mesamol under pressure between the seals. The results have been very mixed, but the risk of running into problems has been so big that it can only be recom-mended to implement these so-lutions if the customer himself takes the responsibility for the solution desired.

          我们可以提供全心全意的支持的唯一解决方案是使用磁性的泵。

        • ROTAN®magnetically driven pumps

        • 使用的泵必须加热并具有耐磨轴承。

          Tar通常运输船只。博上的泵ard bring the tar to the storage tank from which it is pumped to the distillation towers where it is fragmented. During the process about half the tar ends up as pitch.

          This looks like a simple system but there are lots of details that have to be correct to avoid damage to the pumps. Koppers Denmark A/S are specialists in constructing pitch systems where ROTAN® magnetically driven pumps with bearings in solid tungsten carbide are used.

        • Pump Geared for Thin Film Evaporator

        • The pumps are used to transfer the highly purified liquids from film evaporator. Liquids could be lactic acid, fluid vitamin, vegetable oil or poly-glycol, kind of liquid fibre. Normally pump construction is CD26 with mechanical seal running at 500 rpm under differential pressure of 3~5 bar. The pumps are used with gearbox or equipped with Varied Frequency Driven motor.

          The liquid container is under high vacuum with evaporation distillation working on top, and the gear pump shall run at low speed to bring the NPSHr down to a level below NPSHa from the system. This is majorly determined by the installation height difference (liquid flow down by self-gravity).

          This is already the fifth time that Hexiang (the Thin Film Evaporator manufacturer) recommend the customers to choose or use DESMI ROTAN® gear pump, and we are glad to see this kind of strategic partnership bloom and grow.

        • The reliable solution for unsaturated Polyester Resin

        • Rotan Pumpengesellschaft GmbH built a test pump by means of standard parts from the CD + HD/PD pump ranges with stuffing box plus 2 special, machined parts as well as 2 special shaft seal rings and a ground rotor shaft coated with tungsten carbide at the shaft seal area. The pump was equipped with a short suction pipe from the seal housing to the suction side of the valve.

          该泵被称为CD81ERFT,代码3U22PAL,No. 268285,已与大约有间歇性职责。自1997年2月初以来,每天3-4小时,136 rpm x 5 bar x x。4000 CST,没有泄漏。

          • Sugar & Molasses

          • The DESMI ROTAN®泵用于从甘蔗和甜菜汁到糖蜜和成品糖解决方案的不同糖产品泵送。

            The sugar products supplied direct from the sugar mill is chemically neutral whereas imported sugar products may contain small amounts of formic or sulphuric acid in order to prevent fermentation during transportation. Sugar products containing acid may cause corrosion in cast iron pumps so in some cases stainless steel pumps should be used.
