STM Corp is proud to announce the return of a proven performer, the 594 Hydraulic Pressure Test Pump. First introduced by the Deming Pump Co. nearly 100 years ago, and later sold under the Griswold trade name, the new 594 TITAN retains the proven design features of the original, along with updated enhancements. Rugged Cast Iron construction, a simple yet effective packed stuffing box, and the unique lever linked handle, combine for smooth trouble free operation.
Commonly referred to as "a plumber's best friend," the 594 TITAN has many uses including hydrostatic testing of pipelines, boilers, other pressure vessels and plumbing installations. Also suitable for removing obstructions from drain pipes and for testing pressure gauges. Rated for pressures up to 400 pounds per square inch, each 594 TITAN comes complete with brass suction and discharge check valves.
