Double piston pump with S-Transfer Tube KOS
Piston Pump with an S-Transfer Tube
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.
