Thanks to their compact design they have very small
space requirements. All dimensions and connections are
DIN standard; this ensures universal implementation.
BT block centrifugal pumps are normal suction cen-
trifugal pumps in spiral housings for dry installation
with a motor in accordance with IEC standards. They
comprise few parts that are important for their function,
which reduces maintenance work to a minimum. The

few maintenance tasks that are necessary are executed
quickly and easily. Thanks to the low rpm the pumps
are very quiet in operation and are more durable. The
enclosed impeller is highly efficient. The robust BT
block centrifugal pumps are delivered as standard in
grey cast iron. Upon request these pumps can also
be delivered in special materials, such an impeller as
bronze.
