HYDRAULIC PUMPS
NS-1, NS-21, NS-22 and NAP-3
Single-acting, one-speed air pumps.
Air driven pumps for operation where electric power is not available or dangerous.
With safety relief valve, factory rated at the maximum working pressure.
Once the NS-1, NS-21 and NS-22 air pumps are connected to the air line, press down on the back section of pedal for operation. Descent
or pressure release is effected by pressing down on the front section.

BKN-09
Manual and air powered pump.
The pneumatic operation allows for a
faster movement of the piston.
The manual operation is required for
precision pressing jobs or when
compressed air supply is not available.
Recommended air pressure:

. / 100-140 psi
Minimum air flow:

INDISPENSABLE
Important. It is recommended the
use of an air filter-regulator-lubricator
unit with these pumps to resist
corrosion and for longer life.

BES-5, BES-10, BES-20 and BES-30: SINGLE-ACTING
BED-5,BED-10, BED-20 and BED-30: DOUBLE ACTING
They have a two-stage, radial pump that provides a working pressure of 700 kg/cm
2
/10.000
psi.
The first stage allows a quick approach of piston to load and the second stage gives the
effective working pressure.
With precision made components, electric power provides improved operation for applications
requiring high pressure.
With safety relief valve, factory rated at the maximum working pressure. For a continuous
operation, pressure should not exceed 560 kg/cm
2
/8.000 psi.
Frequency: 50 Hz.: 220/380 V - 1,5 kW - 2 HP - 1400 rpm.
Frequency: 60 Hz.: 265/460 V - 1,7 kW - 2,3 HP - 1700 rpm.
