Grundfos offers the market`s widest range of horizontal multi-stage pumps for a variety of different tasks. From pressure boosting to pumping aggressive liquids [including liquids with acids ph2 or alkaline ph13 content], it offers a pump that can handle the job. Grundfos` ch and chn pump ranges are characterized by their compactness and convenient flexibility. And with a failure rate of almost zero, these ranges are the best value-for-money options for professional and domestic applications. Resistance: the two ch ranges are designed to handle liquids of varying aggressiveness. The chn specializes in slightly aggressive liquids and treated water; the ch is geared to handle non-aggressive and non-explosive liquids without particles. Our 100 per cent stainless steel chi pumps are particularly suited to industrial applications as they are able to cope with a variety of liquids at a wide temperature range. Performance: the ch and chn have a maximum head of up to 80 m and the chi up to 75 m. User -friendly: chn and chi pumps are available with an all round shaft seal. This unique-to-grundfos feature enables heavy-duty liquid handling without the need to ever change the shaft seal. Grundfos uses sic-sic composite shaft seals as standard.
