Modular S
Self-priming Centrifugal Pump
The series of DESMI MODULAR S pumps represents one of
the most distinctive developments in self/priming pumps.
Based on many years of experience in the production of
self/priming pumps we supply a pump series that meets
the future demands for economical and reliable pumps.
The individual design, compact with a clear-cut cylindrical
form, together with the practical advantages such as easy
assembling and MODULAR construction of all components
ensure a long a unproblematic operation.
Capacity range:
1-350 m3/h ~ 5-1500 US gpm at 50 cycles
2-400 m3/h ~ 10-1760 US gpm at 60 cycles
Pressure range:
1-100 mLC~ 3-330 ft at 50 Hz
2-150 mLC ~ 6-490 ft at 60 Hz
Temperature range:
With standard mech. shaft seal max. 80oC ~ 176°F, with special
mech. shaft seal max. 120oC ~ 248°F.
The success of the DESMI pumps is among other things
due to the priming principle which is thoroughly described
on the opposite page.
This principle means that the MODULAR S can pump a
mixture of air and liquid and thus evacuate air from the
suction pipe. Thus, priming can be avoided and a foot
valve is not necessary.
Applications for MODULAR S and S/02
Various combinations of assembling
The pumps of the MODULAR S series can be supplied as
free shaft end, mounted on the base plate with petrol or
diesel engine, hydraulic or electric motor or in a closecoupled design with electric motor. They can also be fitted
with a manual friction clutch and V-belt pulley and with
step/up bevel gear ratio 1:2.
MODULAR S/02 Self-priming centrifugal pumps in closecoupled design
This version of the well-known MODULAR S pumps meets
the requirements for compact and reliable pumps and
does not need special alignment. The pumps is connected
to the electric motor via a rigid coupling and can be
mounted with any standard electric motor. The MODULAR
S pumps are constructed of standard components and this
principle has been further emphasized in the monobloc
version.
For optimum flexibility the pump is designed in such a
way that only the coupling and the motor flange have to
be changed in order to fit the selected electric motor. The
monobloc version is equipped with a separate bearing
house with only one bearing, and the rigid coupling is
mounted on the short shaft.
