Product Description
QUICK PUMP-IN OVERSHOT
Roschen's overshots are an integral part of the Q Wireline system. Once the inner-tube is full of core, the overshot is lowered (or pumped-in for an inclined-hole) to the bottom of the hole. Its heavy-duty lifting dogs grab a secure hold at the top of the inner-tube assembly.
For maximum productivity in underground or pump-in applications, the Quick Pump-In Overshot provides significantly improved pump-in rates with dual pump-in lip-seals; as well as new 'V-Lip' pump-in seals in NQ and HQ sizes. The variable profile of the 'V-Lip' seal provides improved performance and accommodates both standard wall and V-Wall drill rods when used with the new Roller Latch underground head assembly.
In addition, this overshot incorporates the proven Roschen "Landing Indicator" ball and bushing. The ball and bushing provide a pump-in valve, a bypass valve, and a landing indicator pressure signal.
