Deepwell turbine pumps are the result of years of research and
constant technical up-dating.  These pumps are used in
artesian or open wells for pumping water from depths of 7 to 100
metres and more, even in continuous operation. Simple and
effective design, high quality
materials, suitable dimensioning and accurate machining, ensure
a long, trouble-free life, high efficiency and reliability.
The PUMP consists of a
multistage body with bowls and impellers made of high quality
line grained cast iron. The mixed flow enclosed
impellers are dynamically balanced and turn on special rubber
wear rings ensuring long resistance to sand abrasion. The
heavy duty carbon steel pump shaft is equipped with impeller
spacing bushes and is supported by rubber bearings. Bronze
impellers, stainless steel pump shaft and footvalve strainer are
available on request.
The DISCHARGE COLUMN assembly
consists of flanged steel column pipe elements, water lubricated
carbon steel line shafts equipped with hard chrome plated
bushings turning on sand resistant rubber bearings supported by
fine grain high quality cast iron retainers. The line
shaft threaded couplings are made of stainless steel.
Stainless steel line shafts are also available on request.
The DRIVE HEAD is available in
four standard versions: vertical pulley, right angle gear,
right angle gear and overdrive, electric motor. The
various types of drive heads available can be used with any type
of power source.
