Page 5: Warnings
Form no.: L453147GB– revision 06/2013 Warnings 1. Read through the instructions before installing the pump and starting it up. If in doubt, contact your local SPX Flow Technology representative. 2. Check that the specifications of the motor and motor control unit are correct. This applies in particular to applications which carry a risk of explosion. 3. Observe that a pump may be unstable and may tilt to the fore onto its inlet port when having a relatively small motor and being assembled on brackets instead of being equipped with a frame with adjustable feet. Be careful during the installation of such a pump. (For this reason, the W+50/600 pump is equipped with an anti-tilting unit.) 4. Do not start the pump before all pipe connections have been fitted carefully and tightened. Special precautions must be taken when the pump is used to pump hot and/or hazardous liquids. In such cases follow the local regulations for personal safety when working... - Page 6 16. The following values specified for the permissible pressure must not be exceeded: Max. 18 bar W+10/8, W+22/20, W+30/80, W+35/55, W+35/35, W+110/130 Max. 14 bar W+25/210, W+30/120,W+50/600, W+50/8, W+55/35, W+55/60, W+60/110, W+65/350, W+70/40, W+80/80 The a.m. values are also valid for the corresponding models in the Wa+ and Wi+ ranges.

Page 9: Installation Of Pump
Form no.: L453147GB– revision 06/2013 Installation of pump Positioning The following must be observed: The pump must be positioned so that the suction pipe is as short as possible and there is a sloping gradient towards the suction port of the pump. Keep the number of valves, bends and tee-pieces on the suction side to an absolute minimum. There must be sufficient space around the pump for piping and access for maintenance. Lining up the pipe system Ensure that the pipe system is adequately underpinned with pipe supports so that the pump body is not subject to strain from or the weight of the pipe system. During the suction process, the pump may tend Caution! to vibrate. A pipe support should be placed close to the pump suction to prevent pipework vibration... -
Page 10: Start-Up And Operation
Form no.: L453147GB– revision 06/2013 Start-up and operation Before starting the pump, dismantle and clean the suction pipe. Any foreign material in the pump should be removed. Checking the pump for foreign material Remove the pump body as described below. The sectional drawing (page 3) is to be used for reference purposes. 1. Disconnect the power supply. 2. Remove the pump body (items 1a, 1b) by unscrewing the clamp ring (item 9a) or body screws, and carefully extract from the body. 3. Turn the impeller (item 4) to ensure that there is no foreign material behind it. 4. Remove any foreign material from inside the pump. 5. When the pump body is clean and free of foreign material, reassemble the pump. Mount the pump body as described below: 6. Check that the locating pin (item 8), which is installed in the top of the back plate, fits with the detent in the pump body and carefully (to avoid damage to the O-ring) press the pump body (item 1a, 1b) in so it covers the O-ring (item 6). Then fasten with the clamp ring (item 9a) or body screws and apply the correct tightening torque. M10: max. 35 Nm (25 ft-lb) 7. -
Page 11: Checking The Pump
Form no.: L453147GB– revision 06/2013 Start-up and operation Checking the pump Fig. 6 To check that the pump is working satisfactorily, pour water into the pump and start it momentarily. Check the direction of rotation. Fig. 6. Listen for any unusual noises. In pumps with water-flushed or steam-flushed shaft seals, the seal chamber must be filled with water/steam. Never allow the pump to run without liquid, as this Caution! will ruin the shaft seal. Starting the pump Check the following before starting the pump: That the shaft guard has been fitted properly. That there is unobstructed access for liquid and that the pump is primed. That the valve on the discharge side is closed. The valve on the discharge side is closed during start-up to prevent the motor from overloading, but should be opened again as soon as the pump has been started. The p ump s hould n ot b e l eft r unning t oo l ong w ithout p umping Note! (typically 15 minutes if the pumped liquid is not hot), because it will get warm and the priming... -
Page 12: Service And Maintenance
Form no.: L453147GB– revision 06/2013 Service and maintenance Checking the shaft seal Check the pump's shaft seal for leaks on a regular basis. If the shaft seal is leaking, replace it or its relevant parts as described below. Replacing the shaft seal The sectional drawing (page 3) shows the position and construction of the shaft seal (applying both to ordinary seals and seals with liquid/steam flushing). Dismantling the pump To replace the shaft seal it is necessary to dismantle the pump. Follow the steps described below and refer to the sectional drawing (page 3). 1. Disconnect the power supply in the motor isolator by removing the fuses and disconnecting the cables. 2. Turn off the steam and flushing liquid supply. 3. Close the pump suction and discharge point and drain the pump housing. If the pump is used for hot and/or aggressive liquids, special precautions must be taken. In such cases, observe the local regulations for personal protection when working with these products. 4. Open the clamp ring (item 9a) or the housing screws once the inlet and outlet pipes have been properly isolated. - Page 13 Form no.: L453147GB– revision 06/2013 Service and maintenance Checking parts for wear 10. Check the O-rings for signs of stiffness, lack of elasticity, brittleness and/or chemical corrosion. Replace worn or damaged parts. 11. Check the stationary ring (item 5.6) and rotary ring (item 5.7) for signs of wear. Wear surfaces must be completely free of cracks. If this is not the case, both the stationary ring and the rotary ring must be replaced. 11a In the case of water-flushed shaft seals and aseptic shaft seals, check the rear seal rings (item 5.6, 5.7) for wear, and replace if necessary. 12. Fit the new o-rings on the stationary seal face and rotary seal face. Remember to moisten these with water. Caution! 13. Fit the rotary seal face on the impeller without using tools. Fitting The notch in the rotary seal face must be installed Note! so that it fits with the driving pin (item 5.8) in the impeller hub. 13a In the case of double mechanical shaft seals, also fit a rotary seal face (item 5.7) with o-ring (item 5.5) in the location on the shaft –...

Page 16: Technical Data
Nominal flow and 60% operating pressure c) 60% flow and max. permissible operating pressure The nominal flow and max. permissible operating pressure in the case of the W+55/60, for example, are 60 m³/hr at an operating pressure of 5.5 bar, and so on. This information only applies if the motor used is an ABB aluminium motor and the size of the motor matches the power requirement of the pump. The noise level may increase considerably if reducers (reduction/ expansion fittings) are mounted on the inlet/outlet. The values shown apply when the pumps operate at 2900 rpm and there is a shroud over the motor. If the pumps operate at 1450 rpm, the values are reduced by approx. 20 dB. The values for the W+25/210 apply at 1450 rpm.
