2. Parallel intensifiersOpposed twin Intensifiers TECHNOLOGY Power drive PumpElectric Servo Pump

3. Advantages parallel intensifiers: -Constant pressure signal = high quality cut - Redundancy (can run with only 2 intensifiers and do the any maintenance when you decide not when the machine breaks down) - No attenuator to be replaced. - Low Cycle time: 30 cycle/minute = Long time between replacement (all things equal there is less wear per hour with 3 intensifiers = longer time between seal replacement) - Air/oil heat exchanger (integrated) PARALLEL INTENSIFIER

4. Disadvantages opposed twin intensifiers - Pressure drops = less quality - No redundancy (production at the mercy of breakdowns) - Attenuator needed (reservoir) that has to be replaced (€ 5.000/10.000) - High Cycle time: 60 cycle/minute = High maintenance costs - Water/oil heat exchanger OPPOSED TWIN INTENSIFIER

5. POWER DRIVE PUMP Disadvantages pd intensifiers - Ultre High Cycle time: 300 cycle/minute = Ultra High maintenance costs due to the high speed and temperature - Working pressure: maximum pressure of 3800 bar = less cutting speed/quality - No redundancy (production at the mercy of breakdowns) - Pump flowrate fixed = high water consumption (water is consumed also when the head is closed) - Intensifier normally used for hydro cleaning applications = low cost, low pressure, low speed

6. Disadvantages electric servo pump -High Cycle time: 60 cycle/minute = High maintenance costs due to the high speed and temperature - Working pressure: maximum pressure of 3800 bar = less cutting speed/quality - No redundancy (production at the mercy of breakdowns) - Attenuator needed (reservoir) that has to be replaced (€ 5.000/10.000) - New technology: how many pump Techni already installed?
