PRESSURE INTENSIFIERS

A complete range of air-to-oil pressure boosters

How it is Composed and how it Works


Alfamatic pressure intensifier series MF is a unit composed of a pneumatic cylinder and an high pressure chamber.
By feeding the pneumatic cylinder with shop compressed air, hydraulic pressures of up to 400 bar are obtained, depending on the models.
The high pressure generated in the hydraulic fluid is directly proportional to the pneumatic supply pressure.

  • It works without lubrication
  • Possibility to turn fluid connections around 360 degrees

Application Examples and Connections


Single Acting Hydraulic Cylinders

With this scheme, the forward stroke of the cylinders is ensured by the MF pressure multiplier.
The thrust force exerted by the cylinders is proportional to the pneumatic supply pressure set for the booster.

Double Acting Hydraulic Cylinders

The forward stroke of the cylinders is ensured by the booster MF, with the thrust force exerted by the cylinders proportional to the pneumatic supply pressure set for the booster.

The return stroke is performed with the aid of the pneumatic spring present in the auxiliary oil accumulation tank (B).

Double Acting Hydraulic Cylinders

With approach and work in sequence
The advance stroke, ensured by the multiplier, is performed in two phases:
1. low pressure approach
2. high pressure work

The return stroke is performed with the aid of the pneumatic spring present in the auxiliary oil accumulation tank (B).
The force of the return stroke is adjusted by varying the air pressure in the reservoir (B).

Accessories


SN 01 Reservoir

All MF multiplier models are supplied with SN 01 type external oil tank.

The tank, fixed to the cylinder hydraulic chamber, ensures the maintenance of an optimal hydraulic fluid level.

The multiplier can be positioned vertcally; in this case, a special fitting that ensures correct positioning of the tank will be needed.

SN 12 Reservoir

The optional SN 12 high capacity tank allows the MF multiplier to be installed in any position.

The tank is connected to the hydraulic chamber of the multiplier via a 1 mt. long high resistance metal braided hose.

The tank must be connected in a raised position with respect to the multiplier.

Fixing Flange

High resistance rear fixing flange in steel, with zinc plating surface treatment.

Foot brackets

Low foot in high resistance steel, with zinc plating surface treatment.
