Lobe pumps are very useful
pumps, as they are the right solution for any kind of pumping
process. Regardless of the application or what are you pumping, how
small or small the flow might be, lobe pumps can help you do
your pumping job with ease in the most efficient way. Lobe pumps
are able to handle solids, pastes, slurries and various liquids. If
wet, lobe pumps offer a superb self-priming performance, a
performance which minimized product degradation.
Lobe pumps offer irregular and
continuous reversible flows and it can operate dry for a short period
of time, but only if flushed seals are used. The flow is independent
of changes in the pressure process, so the output is constant and
continuous. There are special models available for highly abrasive
liquids, shear sensitive liquids or aggressive chemicals.
Lobe pumps characterize with
highest efficiency, reliability, superb hygienic qualities and great
corrosion resistance. The working principle of lobe pumps have
over 50 years of experience and with the years passing by, they
became very easy to maintain. To meet every need and to serve the
broadest applications, there are a few types of lobe pumps,
each with specific user benefits.
Working Principle
The working principle of the lobe pumps is achieved by the
counter rotation of two pumping elements called rotors within a rotor
case. Those pumping elements are located on shafts, which are mounted
within an external gearbox and supported by bearings (which are also
located on the shafts).
The timing gears transmit the energy to the driven shaft and also
synchronize the rotors on a way that they will rotate without making
any contact with each other. As the pumping elements pass the port,
the achieved cavity increases, decreasing the pressure, which induces
the pumped medium to flow into the rotor case.
Applications
Lobe pumps find their use in a
variety of applications in various industries. As they are known for
superb hygiene qualities, reliability, corrosion resistance, easy
maintenance and high efficient, they are most commonly used in food
related industries. For example, lobe pumps are used in the
chemical industry for continuous conveyance of almost any substance
(acids, solvents, resins, solvents, adhesives, detergents, paints,
etc.) while dosing in proportion to rotation speed. Other industries
that use lobe pumps are: pharmaceutical industry (mixing
perfumes or similar additives, drying fatty acid, blending, recovery,
soap and detergent) and sugar industry (glucose, treacle, molasses,
liquids sugar, magma, sugar syrup).
