1 Rotary Joints Series DP

2 Rotary Joints Series DP DP rotary joints are suitable for: hot and cold water modified design -00 for thermal oil Small Series also for hydraulic oil and compressed air high speeds possible due to low frictional torque can be delivered with Atex certification -00 radial and axial housing connections with right-hand thread G/BSP (ISO ). Axial thread with screw plug and gasket. Due to the low frictional moment anti-rotational devices are not required. DP is available in four variants: DP 0, the Small Series, page 11 DP up to 0 with variation -00, page to DP up to 0, the Large Series, page 12 to 1 DPN, the Stainless Steel Series, page 1 to 1 The Standard Series DP -0 Other advantages low frictional torque (important for plastic foil production) long service life easy field repair and maintenance. Both housing and elbow are made of brass and are beadblasted without harm to the environment. The bearings are protected by drain holes in the housing. Rotor made of stainless steel. Two ball bearings, factory-lubricated, maintenancefree up to 0 C; for higher temperatures relubrication through easily accessible grease point required. The internal mechanical seal is balanced and can be easily replaced with other sealing combinations. Combination 1 suitable for water up to 0 C, 3 for water and thermal oil up to 10 C, 4 recommended for contaminated water, for air. Series -00 for thermal oil, equipped with heatstabilised ball bearings, Viton O-rings and axial shaft seal for additional bearing protection. Connection to rotating pressure system by means of standardised connection pieces with right-hand or left-hand male thread G/BSP (ISO ) or NPT (ANSI) sealing and centring face for gasket at end of thread K-flange and conical inner ring ( and larger) fixed flange (F / and larger), sealing with groove and O-ring. Radial housing connection with right-hand thread G/BSP (ISO ) or NPT (ANSI), axial with righthand thread NPT (ANSI) and screw plug. For series Elbows DP Rotary Joints are supplied as one way flow unions which can be converted to two way flow unions by using elbows: P 2... for non-rotating inner pipe (with thread) PR 2... for rotating inner pipe (directly located in elbow) PO 2... for non-rotating inner pipe, which floats within the elbow and O-ring, anti-rotational protection by means of screw. Inner pipes for type PO2 are available. PO as PO 2, but with Viton O-ring for sealing between elbow and housing. Drain Plug and Hose Coupling for drain holes In dusty environment we recommend to block the drain holes with plugs to protect the seal. A drain hose coupling for a mm pipe shall be connected to the o clock position drain hole. 1 set (art.no ) = 4 drain plugs + 1 hose coupling, suitable for all sizes. 2 Subject to technical changes

3 The Large Series DP -0 The advantages of low frictional torque have been maintained. High speeds are possible, too. Balanced mechanical seal. The springs are situated outside of the medium flow. Housing made of lacquered steel. For perfectly fitting cross sections we offer 3 types of housings: for one way flow, two way flow, non-rotating and rotating inner pipe. The inner pipes are supported in the housing, no elbow required. Bearings are factory-lubricated, lubrication point easily accessible. Connection to the rotating pressure system same as Standard Series. Sealing with groove and O-ring. Radial and axial housing connection with righthand female thread as per G/BSP (ISO ) or NPT (ANSI). Anti-rotation device despite low torque to protect the hoses. Set of drain plugs fits Large Series as well. All other technical features same as Standard Series. The Stainless Steel Series DPN The design of series DPN corresponds to that of the Standard Series. DPN is suitable for applications in the food industry or for aggressive media or area. The standard design is made of 4F (1.44) steel. For demanding applications a modified design type -0 is available in 31Ti (1.471). One way flow design is available with radial (1B) or axial (1C) connection. The two way flow design is available for non-rotating (2) or rotating (R2) inner pipe. The radial connection can be used in any position on a radius of 0. Ball bearings, factory-lubricated for life. Connection to rotating pressure system by means of standardised connection pieces with right-hand or left-hand male thread as per G/BSP (ISO ) or NPT (ANSI). Radial and axial housing connection with righthand female thread as per G/BSP (ISO ) or NPT (ANSI). All other technical features same as Standard Series. The Small Series DP 0 Housing made of anodised aluminium. Atex design without anodisation. Ball bearings, factory-lubricated for life. Housing only available for one way flow with radial connection, right-hand female thread G/BSP (ISO ) or for installation into the roll journal with axial connection. Connection to rotating pressure system by means of standardised connection pieces with right-hand or left-hand male thread, only in G/BSP (ISO ). Subject to technical changes 3
