General Data
Application
The MSV, MSVC and MSVN series of centrifugal pumps are multifunctional products designed to convey various
fluids ranging from tap water to industrial liquids at different temperatures, flow rates and pressures. The MSV Series is
designed for non-corrosive fluids, while the MSVC(304SS) and MSVN(316) are suitable for slightly corrosive liquids.
Listed below is a sampling of applications:.
Water Supply Systems: Water filtration and transfer, and pressure boosting in
high-rise buildings.
Industrial Booster Systems : Process flow systems, cleaning systems, high-pressure washing
systems,and fire fighting applications.
Industrial Liquid Transfer Systems : HVAC systems, boiler water supply, condensing
system, car wash systems, and alkalis.
Water Treatmen t Systems : Ultrafiltration systems, reverse osmosis systems,
distillation systems, separators, swimming pools.
Irrigation Agricultural : Farmland irrigation, spray irrigation, dripping irrigation.
Operational Parameters
Thin, clean, non-flammable and non-explosive liquids containing no solid granules and fibers.
Liquid temperature:
Normal temperature type: +70°C, +158°F
Hot water type: +70°C… +120°C, 158°F…+248°F
Ambient temperature: up to 40°C, 104°F
Altitude: up to 1000m, 3280 ft.
Pumps
MSV, MSVC and MSV N Series are vertical non-self priming multistage centrifugal pumps, coupled
to a TEFC IP55 electric motor. The motor output shaft directly connects with the pump shaft through
a coupling. The cylinder and flow passage components are assembled between the inlet and
outlead heads using industrial grade connecting rods. The inlet and outlet are located at the pump
bottom in the same plane , and designed for inline piping connections. The pump can be equipped
to prevent dry-running conditions, phase loss, over and under voltage, over-current, plugged
coditions,and outfitted with other sensory devices designed to protect the pump and process.

General Data
Minimum Inlet Pressure NPSH
In the event that the pressure in the pump is lower
than the steam pressure used to convey liquid,
cavitation will occur. To avoid cavitation, a minimum
pressure at the inlet side of the pump shall be
guaranteed. The maximum suction head can be
calculated with following formula:
H = Pb x 10.2 - NPSH - Hf - Hv - Hs
Pb= atmospheric pressure [bar] (can be set as 1bar)
In a closed system, Pb means system pressure [bar]
NPSH= Net positive suction head [m], It can be read out from
the point of possible max. flow rate shown on NPSH curve
Hf = Pipe and fitting friction loss at the inlet [m]
Hv= Static pressure [m]
Hs= Safety margin Minimum 0.5m delivery head
If the calculated result H is positive, the pump may run
under the max. suction H. In case the calculated result
H is negative, a minimum delivery head at the inlet
pressure is necessary.
En s u r e t h a t t h e p u m p w i l l n o t o p e r a t e i n
c ond it ions t hat c r eat e c avit at ion.
Parallel Operation
Connecting several pumps in parallel will increase
the system output more than a single large pump.
- Applicable to different working states necessary in a
variable flow system.
- Increasing the possibility of water supply when the
pump is in failure. Because in case of pump failure, only
part of the system flow is effected.
Multiple pumps can be connected in parallel to
increase system capacity demands.

Performance Curves
1. All the performance curves are based on the
measured values of a motor at a constant speed
of 3500 rpm.
2. Performance curve tolerances conform
with ISO.
4. Operation of the pump must be within the
performance region shown by the heavier line on the
performance curve to prevent overheating caused by
insufficient flow or motor overloading caused
by excessive flow rates.
3. Measurement is with 20 °C air-free water,
kinematic viscosity of 1mm2 /sec.
