AQTK PUMP IN SEAL
Roschen Supply AQTK Pump In Seals used for AQTK Core barrel.
UNDERGROUND WIRELINE
Roschen boasts a history of leading product technology in core retrieval and wireline systems. In 1921, Roschen introduced the wireline core retrieval system, becoming the first diamond drilling exploration product manufacturer to offer this system. The wireline retrieval system increased productivity on the worksite and made operations more efficient and retrieving core safer.
LINK LATCH QUICK PUMP-IN UNDERGROUND HEAD ASSEMBLY
The Link Latch Underground Head Assembly features dual lip seals and a pump-in valve for faster tripping times and positive latch indication; the location of the lip seals prevents in ground fluid or gas pressure from releasing the latches and eliminates the need for drive keys or tangs to keep the head spinning with the rods.
The head assembly also features the knuckle-head spearpoint for easier unloading of the inner tube in tight spaces, and the new retracting case allows loading of the head assembly into the rods without a loading sleeve.
