Rotary Joints
Series DCDCL and DC Rotary Joints
DCL and DC rotary joints are suitable for hotwater (series DCL up to 180°C, 16 bar and series
DC up to 250 °C, 40 bar) and speeds of up to
1200 min-1. Series DC rotary joints are also suitable for steam up to 250 °C, 40 bar. Typical applications include coating and laminating systems, paper, nonwoven and textile calenders aswell as dryers.
When these media are sealed, there is the dangerof dry run at the seal which reduces reliabilityand service life. The internationally patented
system of series DC successfully prevents thisproblem (EP 0806578, US 5778971). The temperature in the area of the mechanical seal isreduced by means of cooling water to ensure
proper functioning of the units. Flow and temperature sensors monitor operation. Clean,treated and filtered water is required.
Advantages and Features:
䊏 Considerably longer service life as comparedto other rotary joints.
䊏 Greater application data range as comparedto other rotary joints.
䊏 Longer machine running times, easily forecastable maintenance due to temperature
sensor at the mechanical seal. This sensor
monitors the function of the mechanical seal
in the rotary joint.
䊏 The mechanical seal is pressurized from theoutside for superior reliability and low friction
torque.
䊏 Usage of cooling water for the integrated
cooling system.
䊏 An insulating disk protects the mechanicalseal from abrasive pollutants and prevents
the dissipation of heat from the heating circuit
to the cooled seal area.
䊏 Rigid tapered roller bearings for high speed,pressure and additional loads.
䊏 DCL and DC bearing lubrication with hightemperature grease up to 220°C, 25 bar.
2

䊏 The static support in the rotor of the version
with rotating inner pipe (version B2) preventswear at this point.
Special Advantages and Features of DC:
䊏 Double-walled rotor with air gap protects thebearing and seal area from excessively hightemperatures.
䊏 PTFE shaft seal between steam and condensate channel separates the steam from thecondensate chamber to assure reliable discharge of condensate.
䊏 The roller bearings are lubricated by meansof a recirculating oil system in the range from
220°C-25 bar to 250°C-40 bar.
Technical information:
䊏 Rotor and seal housing made of stainless steel.
䊏 Housing parts made of stainless steel(spheroidal graphite cast iron for DCL DN 80– DN 125).
䊏 Housing connections at B and C for DCL
DN 32 and DN 40 through right-hand thread
ISO 228. Other versions with housing connections as per DIN 2635. Flanges according toANSI are available.
䊏 Housing connections B and C can be turnedin increments of 8 x 45° each.
䊏 Connection to rotating pressurized system bymeans of screw flanges.
䊏 Anti-rotation device can be swiveled in increments of 8 x 45°.
䊏 Cooling water supply connection for DCL atposition 180° (for DC at position 0°), coolingwater return connection at position 0°, connection with female thread according to ISO
228. The position of the given connections
must not be changed.
䊏 Bleed screws for DN 80 – DN 125 in the seal
housing 3 x 90° G 1/2.

We reserve the right to technical modifications.
