Middle Level Commissioners,
Cambridgeshire UK
The Middle Level is the central and
largest section of the former Great
Level marshland region, which was
drained in the 17th century. The task
of the Middle Level Commissioners
is to protect the reclaimed land in
the Middle Level area against floo-
ding and to keep the groundwater at
a constant level.
BEVERON concrete volute casing pumps – reliable protection against flooding.
The main body of farmland in the Middle Level area is located up to 3 metres
below sea level and is therefore extremely prone to flooding. The modern pumping
station of St. Germans systematically drains the water into the Great Ouse River
shortly before it flows into the sea, protecting the areas against flooding.
The water level in the Middle Level area represents a particular challenge for the
pumping station: the volume of water varies according to the seasons and the
surface level of the water fluctuates with the tide. Consequently, the pumping
station‘s output has to be continually adapted to the required flow rate and head
which is ensured by variable speed pumps designed to always run at the optimum
operating point.

The particular efficiency and reliability of the BEVERON
pump has proven its worth with large flow rates compa-
red with tubular casing pumps, dry-installed pumps and
horizontal propeller pumps. Furthermore, the impressive
expertise already demonstrated by KSB with Bosman in the
Netherlands was another key factor in the decision to use six
BEVERON 210 concrete volute casing pumps.
In addition to the technical requirements for the pumps,
the customer also wanted to use particularly reliable and
environmentally friendly pumps. The pumping station was
therefore equipped with BEVERON pumps. The customer
was impressed with their wear-resistant Residur® ceramic
bearings, which require no additional coolants or lubricants.
Lubrication is provided by the pumped fluid, supporting the
constantly high efficiency of the pump. The bearing is chemi-
cally and physically resistant to all fluids and solids, making
it extremely durable.
