/Fileunder:A1.00,BP1.03,A4.00,BP4.03High density solids pumps KOS For coarse-grain high density solids and high pressure applicationsIP 1082-6 GBIP 1082-6 GB 3IP 1082-6 GB2... with a high percentage of solid matter and coarse grain with pressures up to 130 barOne feature of the KOS series is its S-transfer tube. This connection of thedrawing-in and pressure cylinders guar-antees an almost continuous operationwith free passage of the material to beconveyed without valves. Individual for-eign bodies in the material to be convey-ed can easily be conveyed with a particlesize of up to 80 % of the outlet diameter.When the S-transfer tube switches over,minimum return flow can occur in isolat-ed cases at very high pressures. This isusually less than 5 % of the stroke vol-ume.In these exceptional cases, it is advisableto use damping systems which excludethis return flow.KOS pumps have free passage withoutany troublesome resistance to flow. They can thus suck in also the stiffest ofsludges.The simple design with very few movableparts reduces the share of wear parts to aminimum. This pump is thus ideallysuitable for the 3 shift operation withhigh service live.The KOS easily handles highly-viscoussludges such as materials to be con-veyed with a high share of coarse grain.KOS-Pumps are especially robust andresistant. Coarse grain that occasionallygets jammed, does not cause any damage.The main field of application ist thus formaterials with most extreme require-ments. These are, for example:n highly dewatered sewage sludgesn sewage sludges with percentages of foreign bodiesn oil sludges with percentages of foreign bodies n bio waste and other wasten chemical and organic high densitysolids with highest viscosityA variety of task-specific componentsand functions are available for extremeapplication. Here are just some examples:n reinforced S-pipes and S-pipe pistonfor shearing off the foreign bodiesn S-pipe with “ears” for a quiet deliveryline at high pressuren automatic reverse pumping functionsfor preventing and automaticallyremoving blockagesn mixer paddles in the feeding devicefor homogenizing the materialsn agitators in the suction housing forextremely stiff and inhomogeneousmaterials n different materials for the machineelements for handling abrasive andaggressive media (e.g. special steelfor the foodstuff industry)n different types of feeding devices onthe suction siden damping vessels n pipeline flanges on suction inlet ofhopper optional with agitator (horiz-ontal or vertical)Water sludgesSewage sludge from filter press and centrifugesBio-waste, special waste, compostFly ash, tailings, coal paste10111213HSPn fine-grain high density solidsn switch-over wihout short circuitingn no reverse flow at high pressuren simple installation of damping vesselsn better efficiency for materials to be conveyed containing a highdegree of air KOSn for high density solids with a highpercentage of solids and coarse,individual foreign bodies up toapprox. 80 % of the pipe insidediameter, resp. pressure outletn less maintenance and wear as thereare less moving parts n less filling resistance due to large,open material inletn hydraulic circuit reliably separatedfrom the material to be conveyed,also if maintenance is poor1415Differentiating features:2 high density solids pumps KOS 1030 to charge sewage sludge into the garbage incinerator in Dinan,FranceThe largest S-pipe piston pump world-wide, manufactured by Putzmeister: KOS 25200 with a conveying performance of 550 m3/h.

The special advantage here: thanks to thespecial design, only one sealing point isrequired.The automatic ringIt is especially difficult to seal betweenthe S-pipe and delivery line when con-veying at high pressure or when convey-ing abrasive material.The Putzmeister solution here:the automatic ring.Under pressure, wear ring R is pressedagainst wear plate B as Ø A is larger thanØ B. The S-pipe slides back within R andis sealed by the O-ring (Fig. 17).Type Inside-Ø Inlet OutletS 1812V mm 180 120S 2015V mm 200 150S 2018V mm 200 180S 2318V mm 230 180mediumS-pipe with cyl. “full flow“ passageThe KOS with feed device THS 332 LIB.

The delivery rate and pressure may beregulated by process control systems,remotely if required. The CI hydraulic pack is particularlyquiet in operation because of its vibrationdamping frame. The hydraulic fluidreservoir has a special coating on theinside which makes it resistant to corros-ion. The electric and diesel power units yieldbetween 11 and 500 kilowatts, moreunder certain circumstances with specialrequirements. The machine is delivered with an open(EHS) or closed hydraulic circuit (FFHE)depending on the volume of fluid requir-ed. For problem-free operation, all essentialinformation (hydraulic fluid temperature,pressure, level of filter contaminationand motor speed) is displayed and re-corded as required. 1617 18192223HCB LCBLIBLCB21LCBThe prepresser unitFor stiff media which cannot be drawn inas they are, prepresser units with self-cleaning screw conveyors are installedon the intake side. The conveyed product in the hopper isintensively kneaded and mixed in thescrew conveyors and then forced in thecylinders to achieve a high level ofvolumetric efficiency. This enables evencompact, moist and almost dry waste tobe pumped into the cylinders. The design of the screw conveyors de-termines the mixing intensity. The wastecontinues to be mixed in the pump anddelivery line due to the turbulent flow. A Mixopress device can dose severaladditives continuously. The prepresser unit is modular and canbe adapted to best suit each individualapplication.

Pig systems:The pig gate allows pigs to be introduc-ed to clean the delivery line without itbeing necessary to open the latter. Thissystem can also be used when themachine is in continuous deliverymode.Damping vessel:Designed as a force-ventilated dampingvessel (active "power damper") or as afree piston damper, the damping vesselensures smooth delivery without inter-ruption during stroke change of thepump. Pressure peaks in the deliveryline are thereby reliably avoided and acontinuous flow is achieved. Putzmeister has been building pumps forconcrete, mortar and all types of solidssince 1958. Reliable engineering andpractical innovations have placed thesemachines among the best of their kindworld-wide. Putzmeister pumps continueto achieve new records for pumping themost difficult material of all – concrete.With almost 200 bar concrete pressure,they can achieve delivery heights greaterthan 500 m and delivery over distances inexcess of 2000 m. In 1978, Putzmeister developed pumpsfor delivering slurry to be used in sewageengineering and throughout industry as awhole. Together with Putzmeister processengineering, PM high density solidspumps today have a wide spectrum ofuses. In sewage works, waste recycling,power stations, dewatering, mining andmany other industry sectors you will findthe right system for every product andevery purpose: from simple pistonpumps with ball valves, through seatvalve pumps, to the powerful shreddingpiston pumps for hazardous waste andhigh pressure-proven S transfer tubepumps. However, all Putzmeister pumps shareseveral features: they are high quality,robust, reliable and economical. Behindthe scenes is the experienced Putzmeisterprocess engineering team who will beable to offer you the best solution forevery application.

In thisway, extremely viscous media – espec-ially sewage sludge – can be conveyedover great distances with low energyrequirements and at considerably lowerpressure. Central lubrication system: Pistons, cylinders and valve stems areforce-lubricated with grease or oil toallow them to withstand the heavy loadsexerted on them by machines and mater-ials. Maintenance costs are reduced as aresult and the safety of the machineagainst dry running is enhanced.

These pipelines canbe laid in a way which is both economic-al with space and best suited to the con-struction. The ZX delivery line system is completelyleakproof and resists high pressures. Thepipes are designed for the specified oper-ating pressure by dynamic calculation,thus rendering them long-lasting andsuitable for non-abrasive media. This isimportant for ensuring permanent operat-ional safety of high pressure lines. Pipes may also be supplied with DINflanges in addition to ZX delivery lines.IP 1082-6 GB Right to make technical amendments reserved · © by Putzmeister AG 2007 · All rights reserved · Printed in Germany (20702RR)Putzmeister AGMax-Eyth-Str. 10 · D-72631 AichtalP.O.
