18 CM COMMON APPLICATION Degreasing and washing of production equipment in industrial environments such as the food and beverage industry mobile-washing units Washing machines vehicle-washing tunnels Units for CIP (Cleaning In Place). Cooling and heating application Pressure boosting

19 GRUNDFOS BOOSTER SET Constant pressure System Standard- On/Off band system Proportional pressure Hydro Multi-S Hydro Multi-E (Electronic) Hydro MPC

20 Note on difficult suction conditions Avoid negative suction wherever possible, if not possible and especially where variable speed drive is required, consider submersible pumps with external VFDs

21 WASTE WATER PUMPS RANGE

22 COMMON WASTE WATER PUMPS

23 SL RANGE

24 SE RANGE

25 SEG GRINDER The SEG pumps are designed with a grinder system which grinds solids into small pieces so that they can be led away through outlet pipes of a relatively small diameter. The pumps are made of wear-resistant materials, such as cast iron and stainless steel. These materials ensure reliable operation. The pumps are available with motors of 0.9 kw and up to and including 4.0 kw

26 WASTE WATER-THE CHALLENGE There has been a major change in the composition of wastewater over the years Moving from largely organic material to huge quantities of man-made materials such as plastics and fibres, as well as a dramatic increase in sand and grit content There has been a significant increase in the number of clogging and jamming incidents There are many water reducing initiatives, such as rainwater harvesting further changing the composition and we are likely to see this trend continue and accelerate in the future
