Bluepump installationinstallation Afripump 1_30

Photos 26 – 30. Installation on an old India MK II or III pedestal.

Before the installation
 
  • Fit a locknut on all the rods
  • Glue a socket on each pipe PVC 70 / 80 mm and the flange on the last pipe
Only keys number 17 and 24 are needed to complete the whole installation.
  
  1. Drill a borehole Ø6 – 8 inches until you have at least > 700 l/h or use an existing borehole and then proceed with nr. 8, or in the case of replacing an old handpump with nr. 11.
  2. Install a PVC casing Ø4 - 4,5 inch with a filter screen of 0,5 – 0,7 mm.(Bluepump 70 / 80 mm casing can also be used by itself, without using other casing) 
  3. Measure the groundwater level and calculate installation depth: >> 5 m below (seasonal) water table fluctuations.
  4. Temporarily close the top.
  5. Put filter sand around the filter screen.
  6. Put clay packer on top of filter sand.
  7. Fill in the space around the casing.
  8. Construct platform (100x30x200cm).
  9. Construct pedestal (50x50x70 cm), use the mold to place the 4 anchor bolts. Wait 5 days for the cement to harden.
  10. Make an open >> 5m. cemented drainage line towards an infiltration pit.
  11. Fit the blue pump box on the anchor bolts or on the existing pedestal.
  12. Attach the rope to the cylinder pipe and wrap the rope around the handle stop.
  13. Lower with the rope the pipes inside the borehole, use handle bearings bolts to secure the rope during the gluing.
  14. Glue the next pipe into the socket. Use the anchor mold to hold the pipe while pushing the pipe into the socket. Lower directly the pipes in the borehole; the rope will hold the weight of the pipes.
  15. The flange comes on the last pipe. Wait 10 minutes for the glue to harden before hanging all the pipes on the flange.
  16. Secure the end of the installation rope inside blue box.
  17. Connect piston rod with pump rod and lower cylinder slowly inside the pipe.
  18. Lower all rods inside the pipe; secure centralizer and all nuts firmly by using two spanners. Use of Loctite is optional. Secure the rod bearing to the last rod.
  19. With the last rod the conical cylinder top should enter into the PVC conical seat.
  20. Move the rods slowly up until you feel that the piston touches the top of the cylinder. Free space should be > 10 cm.
  21. Fit T-piece inside blue box. Put a plastic extension pipe over the outflow. Equally tighten the 4 nuts to avoid leakage.
  22. Fit the spout to the blue box and secure the 2 round nuts inside the blue box.
  23. Fit the handle with the bearings to the blue box and connect the rod bearing.
  24. Measure the discharge per minute, and verify that the water level inside the PVC pipes does not drop after pumping.
  25. Close the blue pump box with the special key and the Bluepump is ready for operation.
