Important: It is essential that the isave and vane pump are serviced in conditions of absolute cleanliness. For a better understanding of the vane pump and isave, please see the exploded views in the sections 5 and 6. The weight of the isave is 65 kg / 143 lb and it must be lifted with suitable lifting equipment. To prevent cold welding, lubricate threads of screws with grease; screw them into the component and tighten them by the hand. Use PTFE lubrication type. Tools needed for upgrading vane pump:: - 10 mm socket - Torque wrench - Adjustable spanner - Loctite mm allen key socket (160 mm long) 1.1 Parts included in the vane pump upgrade kit 180F4161 Qty.

3 2. Disassembling the isave 1. Place the isave on a clean table. 2. Unscrew the bolts in the flange. 3. Remove the vane pump. 180R B1455 DKCFN.PI.003.T

4 2. Disassembling the vane pump 1. Gently adjust the spanner wrench around the coupling and use it as back stop. 2. Unscrew the bolt in the middle of the coupling and remove the coupling. 3. Remove all bolts in the HP out connection flange. 4. Remove the flange. 5. Remove side plate and pin 6. Side plate removed R B1455 DKCFN.PI.003.T

5 7. Gently remove the rotor. Note: Loose parts inside the rotor. 8. Remove vanes. 9. Gently remove side plate and pin. 10. Remove the int. flange 180R B1455 DKCFN.PI.003.T

6 3. Assembling the vane pump - with parts from the vane pump upgrade kit 1. Place the new O-ring and guide pin in the int. flange. 2. Place the new side plate on the int. flange. 3. Side plate mounted correct. 4. Place new stator ring on the int. flange. 5. Turn the vane pump around, so the int. flange faces up. Fasten screws with a torque according to exploded view. 6. Place the 4 new pins in the rotor R B1455 DKCFN.PI.003.T

7 7. Gently place the rotor in the bearing. 8. Position the 8 new vanes in the rotor. The pins may be moved by using a screwdriver. 9. Check that all vanes are positioned correctly. 10. One vane is NOT positioned correctly. 11. Replace the new O-ring on the flange and wet the flange properly with clean filtered water. 12. Position the new side plate over the guide pin. 180R B1455 DKCFN.PI.003.T

8 13 Make sure that the new guide pin is located in the locating hole in the side plate. See # Place the pump housing with the pin orientated upwards. Fit the flange including side plate into both the bearing in the flange and in the stator. 15. Make sure that the guide pin is located in the location hole. 16. Change the new O-ring in the HP out connection flange. Ten new screws 17. Bolt the flange onto the vane pump. Tighten the bolt witha torque according to exploded view. 18. Fit the coupling into the pump. Glue the threat on the bolt with Loctite 270 and tighten the bolt with a torque according to exploded view R B1455 DKCFN.PI.003.T

9 19. Change the two new O-rings in the flange. 20. Install the 2 new labels on top of each product label to cover the old code no. as illustrated above. Spare parts must be ordered according to the new code no. 180F Assembling the isave Correct positions 1. Fit the steel coupling onto the shaft of the pressure exchanger. 2. Fit the polymer coupling insert on the steel coupling. Note correct position of the hole in the insert. 3. Orient both the steel coupling and the 2 guide holes on the vane pump to fit into the pressure exchanger. 4. Mount the bolts into the flange and tighten them a torque according to exploded view, 180R B1455 DKCFN.PI.003.T
