The HMT PIVOT MASTER® Floating Roof Drain System is designed to innovatively provide a better solution to floating roof drainage problems. Introduced in 1982, this system combines the flexibility of the various flexible hose / pipe systems with the strength found in rigid pipe / swivel joint systems. The PIVOT MASTER® Drain System is a steel pipe drain system with flexible hose joints capable of withstanding an extremely wide range of service conditions.
The system effectively provides positive roof drainage with maintenance-free and worry-free operation. This results in extended service life, with no hose kinking or clogging, and no stress loading on O-rings, bearings or seals. Instead of costly swivels, the PIVOT MASTER® employs unique flexible joints in a straight-line design, with no offsets to cause unbalanced loading.
The PIVOT MASTER® is easily installed in a fixed position, requiring a minimal operating area. With a designed continuous slope, the PIVOT MASTER® does not allow sediment to become trapped in the system. It is designed for submerged service with no lubrication required, and there are no corrosion freeze-ups. PIVOT MASTER® components are compatible with 100% aromatic products and can withstand high design pressures.
Standard - For normal floating roof low leg heights;
