Hydraulic system for servicing water pumps in wells

A pump pulling system for extracting an electric pump from a well casing including a plurality of pipe sections threadably connected in series to provide a continuous pipe connected to the pump;

• the pump pulling system being used with a hydraulic lift having a lift cable for selected attachment to the pipe sections being lifted through the well casing;
• the system comprising:
• a pulling unit having means for selectively interconnecting said lift cable and an uppermost one of said pipe sections;
• and
• a head unit for attachment to said well casing and having means for selectively gripping said pipe sections to permit support of said pump and pipe sections while said uppermost pipe section is disengaged from remaining pipe sections.
