Our Rotating Pump Through (RPT) stuffing box is the ideal solution for underground, up-hole and pump-in drilling operations. When pumping wireline equipment, the RPT provides three distinct advantages over other stuffing boxes. Due to its two-part construction, the rod string can be turned slowly during pumping of the overshot and retrieval of the inner tube assembly. This ability to slowly rotate the rods becomes an important feature when drilling in clay or swelling grounds where drill rods can become stuck in the hole and helps prevents delays or shutdowns in operations.
The RPT does not require clean wireline cable, so in the case of broken wirelines, the cable can be crimped or spliced without problem. This ability to save old cables saves time and money. The RPT stuffing box fits most drilling rod sizes with a design that allows for quick and easy changeover to other rod diameters. A simple change of the adaptor sub is all that is required.
- Keeps drill rods moving to avoid getting stuck in the hole
- Allow broken cables to be saved by wireline splicing
- Easy size changeover to other drilling sizes
