Mixing Dispersing Dissolving Evacuating Tasks and solutions with industrially applied dissolvers. Applications High-viscous pastes, undercoats, luting agents, offset printing inks etc. White Lacquers, Priming Colours. Paints and lacquers with easy-to Disperse pigments, Dispersion paints. Dispersion wall paints of medium quality Construction chemicals, inks etc. General remarks related to dispersion Soilds in liquids, the basic material for the majority of dispersed products feature a large number of primary particles which adhere to each thus forming agglomerates, i.e. simple clusters. The decisive objective of a dispersion machine is to be seen in breaking up the agglomerates and in wetting, which means coating, each individual primary particle with the binder film. As breaking up of a substantially round or cubic primary particles is impossible with any other friction machine (such as Pearl mills, three roller mills etc.) the main task remains the wetting cycle, a process in which the dissolver shows distinct economical advantages. Due to the variable speed control the our dissolver copes particularly conveniently and economically with this task. Dispersion with "stationary" dissolvers? The term stationary dissolvers is generally employed for "dispersion machines" with stationary impeller, mostly pole changeable, two-speed motors and a toothed disk not allowing and height adjustment. In our opinion, the use of this type of dissolvers does not provide satisfactory results. If required, the speed can be doubled, the power consumption, however, will then be 4 times as high. We believe that this ratio is too large, as most of the time the machine would then either be under-or overloaded. A matching to the product viscosity cannot be achieved. Height adjustable toothed disks Another important prerequisite is the toothed disk height adjustability. At the beginning of the production cycle, the disk turns just above the vessel bottom in order to start with the necessary reduced binder quantity. The low starting speed prevents the binder from splashing on the vessel wall. These splashes would, with the filling level rising lead to fast and uncontrolled formation of pigment encapsulation which would then be excluded from the dispersion process. Because of the changing vessel filling level the infinite height adjustability of the toothed disk forms a crucial prerequisite, as only then is a uniform product circulation and thus perfect dispersion  guranteed. Economical features of Dissolvers in system comparison Intensive development over many years, especially in the field of Variable Speed Control have led to the increasing capacity and output of our machines. Today a surprisingly large percentage of high quality paint products can be produced on our dissolvers without the use of Pearl mills. Even when particulary difficult to disperse pigments still require the use of other friction machines, the  optimum predispersion is, also for economical reasons, indispensable. Any insufficiently predispersed product not only entails extended cycle times on downstream systems, but will, in addition, be contaminated and quality impaired by abrasion particles from the grinding tools etc. Thus it can be concluded that a neglected or faulty predispersion can never be compensated for during later processing in other friction systems. Though the quantity of the required energy for a full dispersion cycle is identical with all relevant systems, economy can differ substantially. Product heat development dissolvers During the operating process with dissolvers it must be assumed that the electrical energy will unavoidably lead to product heating due to particle friction, a side effect which is advantay&aus for the optimum dispersion process, because the flow behaviour of the product is positively influenced. Trials in the manufacture of white lacquer from titan dioxide pigments resulted in a considerably improved fineness modulus by approx 5 u at temperature of 70° C, thus a better degree of whiteness and gloss as compared with a dispersion temperature of only 60° C. Due to the improved particle wetting in addition to pigment saving, not only the colour intensity development but also the storage stability is positively influenced. Experience has shown that the critical temperature upper limit of the majority of products is clearly higher than the factory reference values for dissolver application. Dispersion tool design A very important prerequisite for the achievement of the dispersion task is a uniform product circulation up to the mixing vessel wall zones. To the best of our knowledge the design of stirring disks, tooth shapes etc. is not decisive. It is even possible that with completely smooth disks of a correspondingly large diameter an excellent dispersion result can be achieved. In practice smooth disks have the disadvantage however that during a pigment addition the contact with the mixed product is not always assured. As opposed to the stirring disk design the pigment concentration in the binder during the dispersion process is crucial to achieving an optimum result. Even if the final viscosity of the majority of the products is low, in all cases the dispersion must take place during the high viscosity phase, (i.e. high pigment phase) An unusually large toothed disk diameter cannot negatively influence the dispersion quality, if however, it exceeds our recommendation for the respective machine, it might lead to a variable speed gear overload. A fact which applies to all variable speed gears in accordance with the laws of physics. Toothed disks and mixing vessel should have a ratio of 1:2 to 1:2.5 High viscosity pastes The increased quality requirements placed on today's products call for growing production equipment perfection. Even pastes and high viscosity products exceeding 500.000 cP which today are frequently produced in kneaders or planetary paddle mixers, can be produced more economically and with considerably better quality using our dissolvers. Even for the production of high quality Polyester chassis mastic and glass fibre reinforced special qualities our dissolver with viscosity dependent Variable Speed Control can be used due to its convincing success. Also here the improved dispersion has a positive influence on storage stability. Production of printing inks For the dispersion of colour pigments for offset printing inks substantial economical advantages are offered as a result of the use of our dissolver. With a product composition featuring high pigment concentration (depending on the type of prepared pigments, between 27% and 38%) a quality product can be achieved, when adhering to our formula proposals, with only one pass in the Three roller mill. Optional : Flame proof drive. Flame proof panel. Electronic speed controller. Vacuum tight arrangement.

The design of the Tuthill Industrial Series incorporates externally timed impellers that are supported in the fluid chamber by double row, ball bearings located out of the product stream.  This design enables the industrial Series to handle highly viscous abrasive slurries, corrosive acids or suspended solids without degradation, aeration or contamination of the product.    

obe pumps are used in a variety of industries including, pulp and paper, chemical, food, beverage, pharmaceutical, and biotechnology. They are popular in these diverse industries because they offer superb sanitary qualities, high efficiency, reliability, corrosion resistance, and good clean-in-place and service-in-place (CIP/SIP) characteristics. Rotary pumps can handle solids (e.g., cherries and olives), slurries, pastes, and a variety of liquids. If wetted, they offer self-priming performance. A gentle pumping action minimizes product degradation. They also offer continuous and intermittent reversible flows and can operate dry for brief periods of time. Flow is relatively independent of changes in process pressure, too, so output is constant and continuous. Rotary pumps also offer superior CIP/SIP performance. Once in line, they can be cleaned without being removed. Depending on the application, it is a good idea to check with the manufacturer to make sure if a particular lobe pump meets both 3-A requirements. As a general rule, rotary pumps require very little maintenance. Some manufacturers offer pumps that allow for seal servicing and maintenance with the pump in line. How Lobe Pumps Work Lobe pumps are similar to external gear pumps in operation in that fluid flows around the interior of the casing.  Unlike external gear pumps, however, the lobes do not make contact.  Lobe contact is prevented by external timing gears located in the gearbox.  Pump shaft support bearings are located in the gearbox, and since the bearings are out of the pumped liquid, pressure is limited by bearing location and shaft deflection. As the lobes come out of mesh, they create expanding volume on the inlet side of the pump. Liquid flows into the cavity and is trapped by the lobes as they rotate. Liquid travels around the interior of the casing in the pockets between the lobes and the casing -- it does not pass between the lobes. Finally, the meshing of the lobes forces liquid through the outlet port under pressure. Lobe pumps are frequently used in food applications because they handle solids without damaging the product.  Particle size pumped can be much larger in lobe pumps than in other PD types.  Since the lobes do not make contact, and clearances are not as close as in other PD pumps, this design handles low viscosity liquids with diminished performance.  Loading characteristics are not as good as other designs, and suction ability is low.  High-viscosity liquids require reduced speeds to achieve satisfactory p erformance.  Reductions of 25% of rated speed and lower are common with high-viscosity liquids. Advantages Pass medium solids. No metal-to-metal contact. Superior CIP/SIP capabilities. Positive suction, nonpulsating discharge. Disadvantages Requires timing gears. Requires two seals. Reduced lift with thin liquids.   Applications Food processing. Beverages. Dairy Produce. Personal Hygiene Products. Pharmaceutical. Biotechnology. Chemical. Industrial. Medium and heavy duty cycles.
