Piston Pump with an S-Transfer Tube for conveying thick media with high solids content The Putzmeister-KOS pump is a valveless two-cylinder piston pump for conveying thick media with high solids content. The pump unit consists of a sturdy pump hopper for reliable feeding of material, two hardened delivery cylinders with one piston each and a so-called S-transfer-tube for connection of the delivery cylinders to the output flange. The changeover of the S-tube is done by two powerful plunger cylinders. Consequently, foreign bodies such as stones or dry running are no problem. Additionally the S-Tube is adjustable to wear in order to use the wear parts extremely long. Two hydraulic cylinders are used as drives for the delivery cylinders. An intermediate waterbox enables flushing and cooling of the cylinders as well as quick replacement of the pistons in case of maintenance. All moving parts are connected to a central grease lubrication (either manual or electrical) system in order to increase their lifetime. Ideal materials to be conveyed with a KOS include sewage sludge and oil sludge with percentages of foreign bodies, bio-waste and other kinds of waste, chemical and organic high density solids with highest viscosity and highly dewatered sewage sludge. The decades of experience in concrete pumping ensure highest reliability and availability to the pump operator. Key Features Reinforced S-pipes and S-pipe piston for shearing off the foreign bodies Low maintenance and less prone to wear and tear due to fewer moving parts Different materials for the machine elements for handling abrasive and aggressive media (e.g. special steel for the foodstuff industry)
