The pumps are based on the geometry and properties of the cycloid. In fact, they are lobe pumps (or internal gear pumps). All of the main components are made of sintered materials. In the development of these two types of technology, we have given an emphasis to high performance in terms of capacity and pressure in proportion to the pump size (owing to the reduction in unused volume), as well as to duration and lower noise level (owing to the porosity offered by the powder metallurgy).
Self-lubrication is another important property intrinsic to every model of this product, and it is a guarantee against buckling.

Rotor pump is also named rotary lobe epump, three-lobe pump, sole pump,etc. When the 2 simultaneous reverse rotating rotors(with 2-4 gears)revolve, it produces suction force at the inlet(vacuum),which intakes the material delivered.The 2 rotors divide the rotor housing into many smaller parts and revo-Ive in the sequence of a→b→c→d.When it revolves to position a,only housing I is filled with medium;when it revolves to position b,housing B encloses part of the medium,when it goes to position c,housing A encloses medium,and finally it goes to position d,then housing A,B and II are interlinked and the medium is transported to the outlet.As this process is repeated，medium(material)is transpor-ted continuously.

The SteriLobe® series offers the ultimate in modular, flexible design to ensure that the appropriate feature set is provided for every application. The pump can be configured to handle nearly every unique pumping problem.
Product Features:
Easy accessibility to seal area enhances cleaning and CIP capabilities.
Generous seal access facilitates simple front loading and removal of seal, even for flushed and double options without stripping the pump.
Cover joint profile improves hygienic characteristics and self-draining capabilities.
Rugged gearbox construction enables the carrying of radial loads.
Stainless gear cover and electro-less nickel plated bearing housing provide clean and corrosion resistant external finish.
Mounting Options: The SteriLobe® range has cast stainless steel bolt-on feet which offer stable and robust support to the pump with the advantage of corrosion resistance. This enables the pumps to be mounted with shafts in the upper or lower position and for ports to be aligned horizontally or vertically.
Rotor Options: 316 SS Bi-Wing or Multi-Lobe rotor options offer clearances to 300°F (150°C), making them suitable for all CIP and SIP conditions. Closer tolerance rotors are also available for low viscosity / higher efficiency applications, and Multi-Lobe rotors are also available in non-galling Alloy 808.

The RTP20 (1.0 liter/rev) and RTP30 series (1.28 liter/rev) design is a proven high-speed rotary transport pump with exceptional performance, advanced durability, application flexibility, and ease of installation to help users achieve enhanced productivity for a lower total cost of ownership. This series’ tri-lobe design, customizable per customer specifications, is compact and light-weight and features removable feet and multiple mountings for easy vertical or horizontal adaptation. Both the RTP20 and RTP30 series efficiently fill rotor voids, allowing for faster and quieter operation on viscous liquids. In addition, with a longer sealing land at rotor tips, the series provides enhanced efficiency when working with lower viscosity products. The RTP20 offers a capacity to 264 GPM (1,000 L/M / 60 M³/Hr.), pressure to 145 PSI (10 Bar), viscosity to 250,000 SSU (55,000 cSt), and operates in temperatures to +230°F (+110°C). The RTP30 offers a capacity to 340 GPM (1,283 L/M / 77 M³/Hr.), pressure to 175 PSI (12 Bar), viscosity to 250,000 SSU (55,000 cSt), and operates in temperatures to +300°F (+150°C). These pumps are available with ACME threaded or tri-clamp ports as well as many other port connection types.

The Power Pump Portfolio.
Roots pumps for Every Low and Medium Vacuum Applications.
Our Roots pumps offer pumping speeds ranging from 250 to 25,000 m3/h. They can be safely employed for low and medium vacuum applications in the coating or semiconductor industry, in research & development, metallurgy or in chemistry and process technology.
The gear and bearing chambers in our Roots pumps are completely separate from the gas pumping chamber. Because the rotors operate without making contact, dry, hydrocarbon-free operation is assured.
A further advantage: Thanks to air cooling, operating costs are significantly lower than with water cooling. The design principle of our proven Roots pumps has also been expanded to include magnetic couplings. These hermetically sealed pumps make oil leaks a thing of the past. We have also developed special pumps for processes that take place in explosive environments or for evacuating explosive gases.
