PCM 150 I20 Progressive Cavity Pump

150I20

The PCM MOINEAU-type progressive-cavity (or e

ccentric-screw) pump is essentially made up

of two internal spiral gears, each of which has the following particular features:

- The stator (external element) has one tooth more than the rotor (internal element).

- For any given cross section, each rotor cross-section is in contact with the stator.

- The helix pitch for both elements depends on the number of teeth.

The rotational movement generates an axial displa

cement of the closed cells, delimited by the

rotor and the stator, from the suction port to the discharge.

The PCM MOINEAU pump is a positive displacem

ent vacuum pump whose cylinder capacity is

equal to the cell volume.

The drive system, flanged directly to the pump, turns

the driving shaft which itself turns the rotor

via a connecting rod.

The bearing option, which enables drive via semi-elastic coupling, is available for our entire

range.
