The Well Pressure Unit incorporates the hydraulic chamber with floating piston. The floating piston separates the polluted well fluid from the hydraulic oil inside the tool. This secures the internal parts work in clean hydraulic oil and eliminates any risk of malfunction due to clogging.

The Well Pressure Units contains the Electronic Timer which opens the needle valve and allows hydraulic pressure force the piston in the Setting Tool, which in turn provides a powerful setting stroke.
