- Page 18 Maintenance 4. Slide out the air system complete with the air valve and the primary air dome. Fig 6 5. Gripping both diaphragms, unscrew and remove either diaphragm from the thrust tube. Fig 7 6. Withdraw the other diaphragm with the thrust tube attached.
- Page 19 Maintenance Fig 9 8. Standard Divider Seal Using a suitable tool, push the divider seal up into the groove until the bottom can be pulled or pushed out and removed. The groove in the body is machined so that it is deeper towards the top of the pump.
- Page 20 Maintenance Fig 13 12. Use a suitable tool to remove the two delivery manifold ‘O' rings. Fig 14 13. Pumps fitted with optional replaceable seats will have 2 ‘O’ rings per seat. Fig 15 14. Unscrew and remove the two bolts securing the suction manifold to the main body.
- Page 21 Maintenance Fig 17 16. Use a suitable tool to remove the two suction manifold ‘O’ rings. Fig 18 17. Pumps fitted with optional replaceable seats will have 2 ‘O’ rings per seat. Fig 19 18. The Flotronic Slimline pump is now disassembled with the exception of the air valve.

Page 22: Assembly Of The Pump
Maintenance Assembly of the pump Assembly of the Flotronic Slimline pump can be easily achieved by competent personnel. Spares required: As identified during inspection. Supplies required: Suitable lubricant (as per site protocol) To assemble the Flotronic Slimline pump, perform the following procedure: 1. - Page 23 Maintenance 5. Install the suction manifold and tighten the two retaining bolts to the torque value specified in section 5.2 Table Example shown in Fig 24 is 1½” to 2” versions. ½” to 1” versions have two manifold securing bolts through the centre of the footplate and manifold to retain the body.
- Page 24 Maintenance 9. Standard Divider Seal Form the divider seal into an oval shape. Fig 28 10. Bend as shown Fig 29 11. Install the divider seal by pushing the seal up into the groove. The groove in the body is machined so that it is deeper towards the top of the pump.
- Page 25 Maintenance 13. Snap Fit Divider Seal Align the divider seal and insertion tool as shown. Fig 32 14. Position the new seal into the bore and using the insertion tool T-020, apply a sharp tap with a light mallet or similar, ensuring that the seal is held central and square to the body.
- Page 26 Maintenance 16. Screw the first diaphragm onto the thrust tube, ensure thread is lubricated. It is recommended that the thrust tube is held in a vice using soft jaws to aid diaphragm fitting and prevent damage to the thrust tube surface. Fig 35 17.
- Page 27 Maintenance 22. Install the air system complete with the air valve and main dome. Ensure that the air system is inserted with the bearings nearest to the air valve side of the pump as shown in Fig 36. Fig 39 23.
- Page 28 Maintenance 25. Fit and hand tighten the main nut. Fig 42 26. Using a torque wrench, tighten the main nut to the torque specified in Section 5.2 Table 3. It is recommended that the air valve is positioned with the silencers pointing down before final tightening of main nut.
