| Hydraulic Cylinder |
The hydraulic cylinder is powered by the hydraulic power unit (HPU). Pressurized oil from the HPU enters the Hydraulic Cylinder and pushes the hydraulic piston, causing the piston to reciprocate. |
| Isolator |
The isolator piece holds the hydraulic cylinder and the high-pressure cylinder together while preventing cross contamination between hydraulic fluid and product fluid. |
| High-Pressure (HP) Cylinder |
Product from the system inlet port enters the HP Cylinder during the suction stroke of the pump, and then pushed out to the EC during the power stroke of the pump. The area of the hydraulic piston is larger than the area of the high-pressure plunger to which it is connected. Process pressure is therefore proportionally higher than the hydraulic pressure. |
