Model 801 Coolant FRU

COOLANT FLUID ROTARY UNION (FRU)


The Model 801 Fluid Rotary Union (FRU) is designed to operate with ethylene glycols (non-silicate inhibitors), propylene glycols and polyalphaolefins (PAO), providing very low leakage rates over relatively long service intervals. The Model 801 FRU can be used as a standalone unit, or can be integrated with electrical slip rings and / or fiber optic rotary joints.

Features

  • 2-pass for supply and return
  • G 1/2 inch BSPP housing ports
  • M14 shaft ports
  • 2x G 1/8 inch BSPP drain ports for leak collection
  • Through bore (for fiber or electric pigtails)
  • Rotational speeds up to 120 rpm continuous
  • Continuous 360° rotation
  • Custom flanges and adaptors available
  • Light weight
  • 100 million revolution life
  • 0.12 mL / hour leak rate

1 Operational life is dependent on pressure, temperature, rotational speed and duty cycle. Maximum values do not apply concurrently. Please consult the factory for actual value.
2 Break-in torque may be higher.
Flexible conduit should be used to couple to the rotating component. The torque arm must be loose coupled.
