PUMP DESCRIPTION AND OPERATING PRINCIPLE OF SIDE CHANNEL PUMPS
The MODULAR V pumps are vane pumps, horizontal multistage magnetic drive. Airtight construction, with
internal cartridge full extension, with magnetic drive meets the requirements of work safety, functional safety
and environmental protection. Conceptually they are constituted by a rotor, within which slide radially in four
blade tribological material, placed at the periphery by a said stator ring, which has as peculiarity the fact of
having a cam profile on the inside. This profile determines the possibility on the part of the vanes, which slide
inside this, to isolate a specific portion of liquid, the liquid that comes from the suction duct, and push it towards
the delivery duct, without the possibility of leakage.
The amount of liquid depends substantially isolated by the eccentricity of the same stator, while the absence of
leakage depends on the precision of execution. At the end of the "rooms" pumping, they are placed two discs,
which in addition to the task to confine axially the rotor, serve at the same time by radial Shaft supporting, acting
as plain bearings.
In the above, it adds the feature of the modular design, which allows to couple several pumping stages, up to a
maximum of 6, allowing it to multiply the discharge pressure produced by the pump. The program includes 13
sizes, referred to as VA, VB, VM with a high interchangeability between components that allows a reduction in
costs of spare parts.
Applications
pumps in general, this model is ideal for clean liquids slightly contaminated, no particles that may become
magnetized;

Other uses are not permitted because you must comply with the conditions of use in "TECHNICAL DATA": the
use of a pump in a plant or in fluid conditions different from those for which the pump was designed, can lead to
dangerous situations for the user.
