Mechanical Packers sometimes called Surface Set Packers, are a low cost, low pressure, hand set Packer for Cased Wells, or Smooth Hard Rock Bored Holes. They are made to be set at 12” depth to 20’ depth. The length is decided by where seal is going to be down hole. They have a limited expansion range, that is why they are not recommended to be used in Open Holes.
Mechanical Packers are operated by tightening a nut on the surface and forcing two pipes to work against each other, which compresses the rubber gland to form a seal. Mechanical Packers are used for Freeze Plugs, Low Pressure Injection, Grouting, Air Sparging, and to control flows out of Artesian Wells. You can adapt Gages, Valves etc. to meet your needs. Made of S.S. & Neoprene Rubber, or if not a factor, can be made with standard pipe. Made to fit the I.D. of the Casing size you are using.
Example, 1.85” O.D. to fit in 2” Sch.40 I.D. casing, 3.75” O.D. for 4” Sch.40 I.D. casing. Give us a call to discuss your needs.
