    3. Installation 3.3 Flushed seal arrangements and pre-start up checks Step 1 A flushed seal arrangement is fitted in order to cool or clean the seal area. It is important that : The flush is correctly connected (see below). A compatible flushing fluid is used and supplied at the correct pressure and flow rate. The flush is turned on at the same time/prior to starting the pump, and turned off at the same time/after stopping the pump.
  • Page 12 3.3 Flushing seal arrangement 3. Installation and pre-start up checks Step 4 Flushing fluid The choice of flushing fluid is dependent upon the fluid being pumped and duty conditions i.e. pressure and temperature. Usually water is used for cooling or flushing water soluble products. For advice on selecting a suitable flushing fluid please contact pump supplier.

  • Page 14: Maintenance Schedule

    4.2 Maintenance schedule 4. Maintenance It is advisable to install pressure gauges on both sides of the pump so that any problems within the pump/pipework can be monitored. Maintenance schedule Your weekly schedule should include : Checking the oil level in the gearcase with the pump stationary. Checking the seals for leakage and replacing as necessary.

    4. Maintenance 4.3 Disassembly Step 1 Before disassembling the pump refer to safety precautions. See exploded view drawings (chapter 6). Removing rotorcase cover. Remove rotorcase cover nuts (13) and cover (12). Step 2 Removing rotors Insert a plastic/wooden block between the two rotors (17) to stop them turning.
  • Page 16 4.3 Disassembly 4. Maintenance Step 5 Removing rotorcase 1. For flushed mechanical seal arrangements, remove the seal housing retaining nuts and ease the seal housing from the rotorcase. 2. Remove the rotorcase retaining nuts (4) and washers (4A). 3. Tap both sides of the rotorcase (9) with a soft mallet. 4.
  • Page 17 4. Maintenance 4.3 Disassembly Step 9 Removing timing gears 1. Release clamp plate screws (40) on pump models SSP-X1, 2 and 3. Release the torque locking assembly screws in several stages on pump models SSP-X4, 5, 6 and 7. 2. Remove gears (36) using the tapped extraction holes provided, or remove shaft assembly as shown in step 10 below.

    4.4 Assembly 4. Maintenance 4.4.1 Fitting bearings to shafts Take care not to damage shaft surfaces, in particular where the seals will be located. Ensure all fasteings are tightened to torque settings as shown in Technical Data (chapter 5). On models SSP-X1, 2 and 3 pumps, bearings do not require heating. For models SSP-X4, 5, 6 and 7 pumps, heat the bearing inner cones to 110°C (230°F) .
  • Page 19 4. Maintenance 4.4 Assembly 4.4.2 Fitting Shaft Assemblies Step 1 Replace the shaft abutment spacer (27) in : On models SSP-X1, 2, 3 and 4 pumps, the bearing bore opposite the rotorcase mounting face with the additional machining mark. On models SSP-X5, 6 and 7 pumps, the right hand bearing bore when viewed from the front of the pump. Step 2 Identify drive and auxillary shaft positions according to gearcase cover (5) orientation.
  • Page 20 4.4 Assembly 4. Maintenance 4.4.4 Checking rotor abutment alignment Step 1 Incorrect setting of rotor alignment will damage the pump. Fit rotors onto shafts (24 and 25) and tighten rotor retainers (22). Step 2 1. Using a depth micrometer ensure axial alignment is within tolerance of 0.012mm (0.0005 in) .
  • Page 21 4. Maintenance 4.4 Assembly 4.4.6 Adjusting rotor timing Step 1 If the rotor timing requires adjustment (and assuming the pump has not yet been re-built), it is important to establish the cause for the rotors mistiming before proceeding. To allow timing adjustment ensure that one shaft is able to rotate within the torque locking assembly/element. The other torque locking assembly/element should be tightened to the recommended torque.
  • Page 22 4.4 Assembly 4. Maintenance 4.4.7 Fitting gearcase cover Step 1 Clean the gearcase cover bore and remove all gasket material from the face. Press a new lip seal (7) into the cover (5). Step 2 Apply liquid gasket to the face of the cover where it mates with the gearcase. Step 3 Carefully slide the cover over the shaft ensuring the lip seal is centred and not cut or damaged.
  • Page 23 4. Maintenance 4.4 Assembly 4.4.9 Fitting primary seals Step 1 Refer to section 4.5 for seal fitting instructions. 4.4.10 Fitting rotors Step 1 If fitted, carefully slide the O rings (18) over the shaft spline until they fit tightly against the shaft shoulder. Step 2 Locate one rotor (17) on to the drive shaft (24) with the dimple at the top.
