By this method of extraction, speed and efficiency is obtained, saving hours of labor. You could have a substantially greater number of valves ready for repacking during a single outage or downtime. This machine can also be used to remove emergency repair sealant from valves and restore them to like-new condition. 

Savings can be enormous and packing extractions up to 50 valves per day are not unusual

DESCRIPTION

MODEL HPZ-95NA

The model HPZ-95NA water, jet packing extraction, system consists of an air operated, high pressure pumping system, high pressure hose, extraction gun, portable reservoir, and nozzle kit. This system has been designed for fast and efficient removal of valve stem packing, pump packing and flange gasketing. It also eliminates the risk of scoring or gouging a valve stem, stuffing box bore, or flange face cause by out-dated manual extraction methods. The HPZ-95NA system allows for instantaneous flow control at the gun without the use of any electrical or pneumatic remote controls or switches. The DSG-20 Extraction gun is a hand held device that is activated by depressing a gun type trigger. This allows for a safe and positive flow shut-off control at the gun.  Releasing the gun trigger stops all jetting flow instantaneously, regardless of the distance from the pumping  unit. When the trigger is  released, the pump unit will  stall at the preset operating  pressure. The HPZ-95NA provides the operator with  the ultimate in safety and  positive control of the  amount of water or chemical used in the extraction process.

 

Why struggle to remove worn, dried out, burnt, rock-hard valve and pump packing?   A high pressure water jet penetrates and removes rock hard packings quickly and cleanly without damage to valve stem or stuffing box. Extraction, speed and efficiency is obtained, saving hours of labor. You could have a substantially greater number of valves ready for repacking during a single outage or downtime. This machine can also be used to remove emergency repair sealant from valves and restore them to like-new condition.

The HPZ-95NA Mini Water Jet Packing Extractors are designed to remove rock-hard wire bound packings as well as tedious graphite / graphoil packings and injected sealants that become like solid concrete. The high pressure water jet concept saves days of manual labor costs and REM (radio-active exposure man hours) in nuclear power plants. It eliminates the use of packing pullers and packing picks that damage stuffing box bores and valve stems, thus forming leak paths. It allows for the extraction of packing in small valves with tight stuffing boxes that packing pullers can’t enter or packing picks won’t penetrate. The HPZ-95NA is the only logical means of packing removal for expensive control valves and ALL valves and pumps in general.
