Double piston pump with S-Transfer Tube KOS
Piston Pump with an S-Transfer Tube
Overview
Built for the way Texas crews work
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.

Reinforced S-pipes and S-pipe piston for shearing off the foreign bodies
S-pipe with "ears" for a quiet delivery line at high pressure
Automatic reverse pumping function for preventing and automatically removing blockages Mixer paddles in the feeding device for homogenizing the materials
Agitators in the suction housing for extremely stiff and inhomogeneous materials Different materials for the machine elements for handling abrasive and aggressive media (e.g. special steel for the foodstuff industry)
Different types of feeding devices on the suction side
Damping vessel pipeline flanges on suction inlet of hopper optional with agitator (horizontal or vertical)
