Single piston pump of the EKO series - Putzmeister Solid Pumps

For media that you previously thought ofas ”not capable of being pumped“In contrast to the alternative transportmethods, „closed“ transport in pipelineswith efficient piston pumps is becomingmore and more widespread.Possible applications■ Highly dewatered sludge from filterpresses12Older types of high density solids pumpswith double pistons are limited in theirapplications by the fact that the cylindermust be filled with material before thefeed stroke takes place.The EKO single piston pump, on theother hand, works on the thrust principle.Bulky material is fed into the feedchamber – if needed, forced in. Finally, apiston pushes the medium out of the feedchamber into the delivery line.Since the feed chamber has a large opening,it can be fed with bulky or hard tohandle materials.■ Dried paper pulp■ Hazardous waste from barrel comminution,including shredded barrels■ Screenings from sewage treatmentworksThe variantsDepending on the requirements, the EKOcan be supplied in either single pump,dual pump or crown version.The Single EKO is designed for standardapplications and is particularly suitedfor charging of incinerators.Shredded barrel material pumped with sludgeBiomass13Where a semi-continuous delivery orlarger feed output is required, the EKODuo is used (Fig. 10). Two independentsingle cylinder pistons feed into a shareddischarge line.14The EKO Crown handles the most difficulttasks and is even able to cut uplarge foreign bodies contained in thematerial.Screenings from sewage plantsHousehold refuseProcess flow diagram for the conveyanceof paste-type and solidwaste materials to a rotary kiln15Barrel shreddingRotorblades IIntermediate bunkerFilter cake ofpaste-type wasteEKO 14100Mixing bunkerRotorblades IILevelmeasurementSludge lanceRotary kilnAshFly ashWasherChimneyIP 2253-3 GB
