General Data
Pump
Non-self-priming single-stage centrifugal volute pump
With axial suction port, radial discharge port and
horizontal shaft components.
The ND pumps have dimensions and nominal
performances according to DIN 24 255 (10 bar) but are
designed for 16 bar operation wherever the shaft seal type
allows it. ND pumps according to DIN 24 256 (16 bar) are
described in a separate booklet.
For a pump of same the model, the performance can be
changed by trimming the outer diameter of the impeller.
Only four shafts are required to cover the total range, and
this gives many common interchangeable parts for pumps
fitted to the same shaft. Just like the shaft, the bearing
house has only five sizes for the whole series.
The pump has a back pull-out design, and when a suitable
spacer coupling is fitted to a direct coupled unit, the
casing and motor can remain in position while all other
pump parts can be removed for simple and quick
maintenance.
ND pump set are comprised of ND pump and standard
electric motor which are connected by coupling and
mounted on a steel metal base.
The advantage is that we could easily select the motor
and couple to the ND pump. The coupling adopts the
flexible pin and bush design, which makes the pump set
more stable with minimal vibration and longer life-span as
compared to the ‘claw-type’ coupling. The steel metal base
is joined by profiled steel bar for strength. Fitting surface
where the pump and motor foots seated, are lapped
by machine with high precision. The coupling guard is
designed to cover the coupling to provide greater safety
and security.
