Product description
High-pressure water system
Intensifier
Ceramic plungers connected to each side of the piston extend into the left and right high-pressure cylinders.
Hydraulic fluid pushes the piston to 1 side while low-pressure supply water fills the empty cylinder. The plunger
on the opposite side of the cylinder compresses the water for piercing or cutting.
The plungers in the intensifier compress water up to 4,136.85 bar or 413,685 kPa (60,000 psi). This pressurized
water exits the high-pressure end through a check valve and goes to the attenuator.
Attenuator
The piston stroking causes a brief change of water pressure in the high-pressure ends. The attenuator
compensates for pressure fluctuations and maintains a consistent output water pressure.
Pumps with a 2-liter attenuator have an attenuator guard, which is supplied for safety.
Bleed-down valve
The bleed-down valve is a normally open, hydraulic-actuated dump valve. When the pump is turned off or it is
changed from cut-pressure mode to pierce-pressure mode, the valve opens to discharge water from the system.
High-pressure water
This water has been pressurized by the intensifier for piercing or cutting. It is also called
CUTTING WATER OUT.
