Mechanical Research & Design, Inc. employed a multi-stage PE sealed tool design to perform remote redundant active mechanical sealing and pressure load restraint, providing an NSF® 61 compliant tool using exotic stainless steel and elastomeric materials. The system was manufactured, assembled, tested, and optimized in the Lab at Mechanical Research, ensuring the tool would perform as expected at the installation site. Using a system of special hydraulic cylinders and motors powered by potable water, the SEALFAST® mechanical seals and traction restraint pads functioned as anticipated and the tool has been currently installed successfully. The long tool length was required for the multi-stage drive system, allowing the customer to partially actuate the tool to perform tests during installation prior to locking the tool in place once leak stoppage was confirmed.
