Water rotary union SE 16

for oilfor gasfor air

Description
SE Series 16-passage rotary unions provide 16 independent flow passages for simultaneous transfer of multiple fluid circuits through a single rotating interface. Units are engineered for high-pressure environments and compact installations. Standard models include threaded radial side connections on both shaft and housing; optional shaft O-ring glands are available for face/flush mounting (specify at order). SE Series units can be combined directly with electrical slip rings to enable concurrent fluid and electrical/data transfer.

Key Features

• 16 independent flow passages
• Rated for high pressure applications (up to 7,500 PSI / 515 BAR)
• Compact design for installations with limited axial space
• Standard: threaded radial side connections on shaft and housing
• Optional: axial O-ring shaft glands for face/flush mounting (must be specified at order)
• Compatible with standard electrical slip rings for combined fluid and electrical/data transfer

Available Configuration Example
Part # | Connection | Passage Size | Diameter | Length | Through Bore | Min. Torque*
SE-11161 | #4 SAE-ORB [G1/8-28 BSPP] | 0.187 in [4.75 mm] | 4.437 in [112.7 mm] | 13.700 in [347.98 mm] | 0.375 in [9.525 mm] | 166 in-lbs [18.76 Nm]

Shaft Connection Options

• Standard: radial SAE-ORB or BSPP connections (radial ports; plugged if axial connection ordered)
• Optional: axial O-ring face seal connections (must specify at time of order)
• Threaded mounting holes available

Optional Interface Mounting

• Shaft flange mount
• Housing flange mount

Warnings / Notes

• Water/Glycol or coolant media must include rust inhibitors
• Oil/hydraulic media must be petroleum-based
• Operational life depends on rotational speed and duty cycle; required torque to rotate may increase with different media or during dry running
• For temperatures above 220° F (105° C), alternative seal materials are required; use of water above 212° F (100° C) also requires alternative seals
