Sentry’s Test and Torque Units for field service are Sentry’s design built by Reliable Pumps. These Units feature the Reliable RD 3015 DHT Series triplex pump for operation of the hydro test unit and a DYNEX PF-1002 hydraulic pump powering the hydraulic torque wrenches. Both pumps are serviced by the Perkins 80 HP Diesel power plant. While these test and torque units are normally trailer mounted, they can be constructed on a skid as well. All test and torque units (TTU’s) are good for 15,000 PSI pressure testing and 10,000 PSI hydraulic torque wrench operation.
