Ball valve pump KOV
A Low-Cost Piston Pump with Ball Valves
The Putzmeister KOV-pump is a low-cost two-cylinder piston pump with
ball valves for the economical transport of fine-grained mortar and
slurries. Small foreign objects up to a maximum size of 20 mm can be
easily transported. The pump unit consists of two hard-chromed
delivery cylinders and each of them alternately pumps the medium into
one delivery line (KOV) or into independent delivery lines (KOV DUO).
Following this method, the pump can also supply two injection sites
at the same time. An intermediate water-box enables flushing and
cooling of the cylinders as well as quick replacement of the pistons
during maintenance work. The number of parts which are prone to wear
and tear is minimal.
Heavy duty ball valves are used for rigid media and in case of
flow-able media, rubber-coated balls will be used for sealing and in
order to prevent the steel head from wearing out. Decades of
experience in concrete pumping ensure highest reliability and
availability to the pump operator. Valve discs and valve seats are
made of highly wear-resistant steel which ensures long life of the
pump and reliable operation.
