  • Page 8: Applications

    Applications The SSB Retractor can be used to clean from simple tanks and ductwork, to complex process applications with agitators where it is not possible to use fixed spray balls. Applications such as Storage Tanks, Reactors, Mixers and Spray Dryers including Ductwork and Vent Lines can all be cleaned by use of one or multiple SSB Retractor units.

  • Page 26: Maintenance

    Maintenance The units are designed to be self cleaning and should require very little or no maintenance between service intervals. The units are a simple design with only the central telescopic bore being wetted. Performance will be effected by contamination from debris or particles where the CIP system is inadequately filtered or swarf in the system after installation.
  • Page 27 Maintenance (continued) Carefully withdraw the Inlet Adaptor from the Main Body tube. Ensure to be careful & keep the Inlet Adaptor parallel with the Body Tube as it is withdrawn. Two seals will now be visible on the end of the inlet adaptor stem. The larger seal at the end of the inlet adaptor stem is the cleaning media seal and the second smaller seal is an air seal.
  • Page 28 Maintenance Continued) Remove the second clamp between the Main Body tube and the Home Chamber and carefully slide the Body Tube from the Piston to reveal the spring. See Figure 10. Figure 10 There is another Solid Gasket Spacer Ring & two O-rings between the Home Chamber & the Body Tube.
  • Page 29 Maintenance (continued) Once the Body Tube is removed the Piston Slide ring will fall away from the Piston. This is normal. See Figure Figure 12 CAUTION: To remove the Piston the Circlip inside the recess of the Piston has to be removed. The Spring is under compression at this stage so the Piston must be held downwards as the Circlip is removed to avoid the Piston being ejected by the spring.
  • Page 30 Maintenance (continued) The remaining seal visible on the Piston in Figure is the Main Air Seal. This seal is a PTFE ring with an O-Ring underneath to energise the seal. Figure 14 Look inside the piston, there is an O-Ring which seals the piston to the spray stem. This seal should be carefully removed using a small sharp pointer pressed into the O-Ring.
  • Page 31 Maintenance (continued) Remove the spring from the remaining body of the SSB Retractor. Remove the Orientation Screw (if fitted) from the Spray Stem as shown in Figure 8 using a 2.5mm Allen key. Retain the screw as it will be required in the re-build. The Orientation Screw is fitted to ensure the orientation of the spray pattern.
  • Page 32 Maintenance (continued) Once the orientation screw is removed, push the spray stem forward to reveal the spray ball. The Sprayball is retained by a 2mm diameter pin which passes through the neck. Straighten the end of the pin with a pair of pliers. See Figure 17. Figure 17 Once the Pin is removed the Sprayball can be unscrewed (anti clockwise) &...
  • Page 33 Maintenance (continued) The spray stem can now be drawn out of the main housing. See Figure 19. Figure 19 To remove the sleeve from the main housing the 3mm dia. roll pin should be driven into the housing using a 2.5mm pin punch. (When rebuilding, a new pin must be used.) See Figure 20. Figure 20 Instruction Manual, SSB Retractor - Mini Retract-A-Ball Page 31...
  • Page 34 Maintenance (continued) Remove the Sleeve from the main housing to reveal the O-Ring seal. This seal should be carefully removed with a small pair of long nosed pliers & discarded. See Figure 21. Figure 21 The product seal can be seen in the large end of the sleeve. This Seal should be carefully removed using a pair of long nosed pliers &...
  • Page 35: Re-Build & Fitment Of New Service Repair Kit

    Re-Build & fitment of New Service Repair Kit The Service Repair Kit for the SSB Retractor unit is- TE75P287-90 for standard EPDM seals. For units TE75P231 & TE75P251 TE75P287-94 for Perfuorolastomer seals. For units TE75P231-04 & TE75P251-04 Both of the above will also require a Seal Installation Tool Kit to help fit the seals TE75P299 - Seal Installation Tool Kit.
  • Page 36 Re-Build & fitment of New Service Repair Kit (continued) Carefully hold the Inlet Adaptor Body in soft jaws in a vice & using a 13mm spanner unscrew the Inlet Adaptor Stem (anti clockwise). The end of the stem is fitted with an O-ring. Remove the O-ring & thoroughly clean around the O-ring groove.
  • Page 37 Re-Build & fitment of New Service Repair Kit (continued) Place the Air Seal Fitment Tool Part TE75P593 over the end of the Inlet Adaptor Stem as shown Figure below in This will allow the Air Seal part No. TE75P518 to be slid over the tool & into position on top of the Energising O-ring.
  • Page 38 Re-Build & fitment of New Service Repair Kit (continued) This process will stretch the seal & it will appear to be too big. Remove the tools & begin squeezing the seal with fingers to reduce its size. Move around the seal several times with fingers until the seal has returned almost to its original size.
  • Page 39 Re-Build & fitment of New Service Repair Kit (continued) Fitting of Stem Product Seal Part No. TE75P543 Place the Stem Product Seal in the end of the Sleeve. Position the seal so that one side of the seal enters the seal groove. Carefully work around the seal, pushing it into the groove. Care must be taken not to kink the seal.
  • Page 40 Re-Build & fitment of New Service Repair Kit (continued) Fitting the Sleeve into the Home Chamber. Lightly wet the O-ring on the Sleeve with clean water & offer up to the Home Chamber. Rotate the Sleeve until the 3mm Spring Pin hole aligns with the hole on the Home Chamber. Push the Sleeve into the Home Chamber &...
  • Page 41 Re-Build & fitment of New Service Repair Kit (continued) Fitting the Spray ball to the Spray Stem. Ensuring it is clean, gently screw the Spray Ball all the way onto the Spray Stem. Slowly back off the ball on the thread until the small slot in the neck of the ball aligns with the hole in the Spray Stem.
  • Page 42 Re-Build & fitment of New Service Repair Kit (continued) Fitting the Spring. Push the Spray Stem up so that the Spray Ball enters the Home Chamber. If the Orientation Screw is required (if a targeted spray pattern is being used) rotate the Spray Stem until the M3 thread is visible through the guide slot in the Sleeve &...
  • Page 43 Re-Build & fitment of New Service Repair Kit (continued) Fitting the Piston/Stem Seal Part No. TE75P541 or TE75P575. Fit the Piston/Stem Seal into the Internal O-ring groove inside the bore of the Piston. See Figure 38. Figure 38 Fitting Piston Seal & Energising O-ring Parts TE75P515 & TE75P516 or TE75P546. Put one side of the O-ring (TE75P516 or TE75P546) into the O-ring groove of the Piston &...
  • Page 44 Re-Build & fitment of New Service Repair Kit (continued) Fitting the Piston. Stand the Retract-A-Ball assembly on the face of the Home Chamber so that the Spring points upwards. Place the Piston Spacer onto the Spring as shown. Place the Ring Magnet onto the Spring Spacer if required.
  • Page 45 Re-Build & fitment of New Service Repair Kit (continued) Place the Piston onto the Piston Spacer & push downwards, compressing the Spring so that the Spray Stem enters the Piston. Push down until the Piston is fully seated. Warning: DO NOT LET GO OF THE PISTON AS THE SPRING IS UNDER COMPRESSION. Fit a new Circlip Part No.
  • Page 46 Re-Build & fitment of New Service Repair Kit (continued) Ensure the Body Tube is clean & check the internal bore for scratches as this bore forms the air seal with the Piston. Carefully lower the Body Tube over the Piston & Air Seal, take great care not to damage the Air Seal.
  • Page 47 Re-Build & fitment of New Service Repair Kit (continued) Carefully align the end of the Inlet Adaptor Stem in the end of the Spray Stem & push down. Ensure that both seals on the Inlet Adaptor Stem pass in the Spray Stem & do not snag. See Figure 45.
