2.1 Description of the pump
2.1.1 CombiLine (CL)
The CombiLine is a built-in in-line circulation pump range. These pumps are easy to
install in straight pipelines, inlet and outlet flange connections have the same size and
pattern and are positioned in-line.
2.1.2 CombiBlocHorti (CBH)
The CombiBlocHorti is a close-coupled foot-mounted pump range. These pumps are
characterised by a compact build and a pump casing with horizontal inlet and vertical
outlet.
2.1.3 General
CL and CBH share the same impeller, shaft seal, and drive section (Back-Pull-Out unit).
For this design the electric motor is provided with an extended, stainless steel motor
shaft. The impeller is directly mounted onto the motor shaft. The pumps are provided with
a rubber bellows mechanical seal, according to EN 12756 (DIN 24960).
The pumps are available with single- and double-speed electric motor. Frequency
controlled motor drives are available for the single-speed electric motors. These electric
motors are standard suitable for 50 Hz and 60Hz. The speed of the electric motor can be
controlled in a frequency range from 10 Hz - 60 Hz.
➢
Running the pump at the lower speed will result in considerable energy savings.
