D Series rotary unions are designed for the passage of water, hydraulic oil and gas to a temperature up to 100°C.
They are equipped with a double mechanical seal which allows the rotation of 2 fluids at different pressures. They are fitted with ball bearings for maximum performance at higher rotation speed.
The construction materials are:
- AISI 420 for the rotor
- Aluminium for the housing
The mechanical seal is achieved by matching resin impregnated graphite with tempered stainless steel.
The Standard supply provides the rotating nipple threaded cylindrical GAS and we manufacture different standard versions upon request (NPT, metric, ecc…)
- 100% made in Italy, entirely manufactured in our plant
- Standard versions always on stock!
