2. GENERAL
2.1. Definition of Pump and Usage Areas
The HEXA multistage in-line centrifugal pumps are
designed for the following applications:
• Municipal water supply and pressure boosting
• Domestic water supply
• Boiler feed and condensate systems
• Cooling water systems
• Irrigation and dewatering
• Fire fighting
• Washing plants and washdown
• Water treatment plants
• Reserve osmosis systems
Thin, non-explosive, non-corossive liquids, containing
no solid particles or fibres.
When pumping liquids with a density and/or viscosity
higher than that of water, motors with correspondingly
higer outputs must be used, if required.
CAUTION
Please contact MAS DAF MAKINA SANAYI A.Ş. for
liquids that have different chemical and physical
specifications.

Product Information as per Regulation No. 547/2012 (for
Water Pumps with a Maximum Shaft Power of 150 kW)
Implementing "Ecodesign" Directive 2009/125/EC
Minimum Efficiency Index for MAS OMK-V Pump Series
is shown on the pump label.
MEI values of MAS OMK-V Pump Series are shown on
the pump characteristic curves.
Minimum Efficiency Index for MAS OMK-V Pump Series;
Minimum 0.4. (MEI≥0,4)
‘Vertical multistage water pump’ (MS-V) means a
glanded multi stage (i>1) rotodynamic water pump in
which the impellers are assembled on a vertical
rotating shaft, which is designed for pressures up to 25
bar, with a nominal speed of 2900 rpm and a maximum
flow of 100 m 3 /h.
Efficiency values of the pump characteristic curves,
which are cut diameter, are expressed in %.
OMK-V Series water pumps, the pump efficiency can be
achieved more than fix speed in case of variable speed
control.

2.2. Performance Information
Actual performance of the pump can be obtained from
the order page and/or from the test report. This
information is given on the pump label. The
performance curves given in the catalog are valid for
water whose density and viscosity are ρ =1 kg/dm
3
and
ν =1 cst. respectively. For those liquids whose densities
and viscosities are different from those of water, please
consult with MAS DAF MAKINA SANAYI A.Ş. since the
performance curves vary with density and viscosity
CAUTION
Do not operate the pump with a motor that has a different
power except for the given catalog and label values.
The pump is not to be operated at off-design point given in
the order and supplied from the firm.
It is necessary to ensure that the instructions are obeyed
for the safe running of the pump.
2.3. Warranty Conditions
The entire products in our selling program are warranted by
MAS DAF MAKINA SANAYİ A.Ş.
The warranty conditions will only be valid when all the
instructions about installation and start-up operations of
the pump unit are taken into account.
2.4. Test
All Pumps are dispatched for sale when all the performance
and pressure tests are completed. Proper assurance of
material and fault-free operation of pumps whose
performance tests are made is under the warrantyof MAS
DAF MAKINA SANAYI A.Ş.
2.5. Pressure Limit
Pressure at the discharge flange must not exceed 10 Bar. A
special order is necessary for applications with higher
pressures.
