Rotary Lobe Pumps
Pumping fluids that are highly viscous, abrasive,
laden with solids or all of these things is the daily task for the
Megator Lobe Pump. Due to a number of
carefully engineered features, the Megator Rotary Lobe Pump
manages such a task whilst ensuring a low life cycle cost.
The gentle action of the two interacting rotors
creates a fluid movement through the pump, with minimal damage to
suspended particles. Various types of rotor materials can be
used, combined with a wide range of materials for all other wetted
parts, resistance to wear and corrosion are obtained.
The special design of the Megator Lobe pump allows
dry running, as the standard mechanical/lip - seal system is
constantly lubricated. The same lubrication acts as a seal
detector, allowing the user to react swiftly in case of any leaks
occurring. Typical fluids handled with the
Megator Lobe Pump are: Sludge with high
dry-matter content, mud slurries, chemicals, centrifuge feed fluid,
meat offal, cement slurry, gypsum, sauces with vegetables, marmalade
etc.

How the Rotary Lobe Pump Works
As the lobes disengage, they create an increasing
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 areas between the lobes and the casing - Liquid does not flow
between the lobes. As the lobes
re-engage, the liquid is forced through the outlet port under
pressure. |
