Self-Conteined Hydraulic System
The CHA is a Self Contained Hydraulic System with the following components:
- Hydraulic pressure Pilots set (high and low pressure).
- Manual hydraulic pump with oil reservoir, relief, valve and vent valve included in the same block.
- Pressure accumulator.
- Pressure gauge.
- Stainless Steel tubing and fittings.
Advantages:
- It does not require external power (pneumatic, hydraulic, etc.) eliminating the need to install auxiliary equipment and the laying of pipes.
- It can be installed in gas or oil wells.
- It is free of maintenance.
- It works by means of a closed hydraulic circuit that keeps the seals always clean and lubricated.
- It can be easily calibrated in the field
