Stuffing boxes

Stuffing boxes SUSG-73-32HL-М, SUSG-73-32HL-М1, SUSG-73-32HL-М2 are designed for capsulation of polished rod of sucker-rod pump of a well. Stuffing box structure assures the following:

• automatic shutdown of well spring in case of rod breaking-down;
• replaceability of stuffing box without well killing operation;
• balancing of radial movement up to 4 mm at that keeping capsulation up to 1500000 cycles without replacement of sealing cup.
• Environmental safety during use of sucker – rod pumping unit.
• Capsulation of well spring at the time of long downtime (awaiting of repair, at flooding (overflow of river, lakes) by shut-off device – preventer).

In terms of design stuffing boxes are made in 3 designs with various functional capabilities.
