KOS S-Tube Piston Pump

 Features and advantages


In the KOS series the intake and delivery cylinders are connected by an S-tube. This permits the material to be pumped straight through without interruptions or mechanical obstacles and without any valves. Foreign substances in the material can therefore be conveyed without problems up to a maximum particle size of 50 % of the delivery material.

The KOS pump is particularly suitable for conveying highly viscous sludges and other material with a high content of coarse solids. The KOS series finds its principle application with materials presenting the most extreme requirements, such as dewatered sludges which contain solids, oil sludges, high-viscosity solids, etc.

A wide range of application-specific components and functions are available from Putzmeister. The easy installation of the pump as well as the little quantity of wear parts form a robust and low-maintenance pump working with low operational costs.
