2. HANDLING
Read these instructions carefully before beginning installati-
on. Lift and handle these pumps carefully. PVM/PVMI/PVMX
series are vertical multi-stage non-self priming pumps cou-
pled with standard electric motors. This manual applies to
standard version pumps and for standard applications.
3. APPLICATIONS
PVM/PVMI/PVMX series in-line pumps booster pumps are de-
signed for a wide range of applications in various industries
– for water treatment, water boosting, water supply, cooling,
cleaning, etc.
Pumped liquids
These pumps are designed for use with clean, non-viscous
and non-explosive liquids that do not contain abrasive matter.
WARNING: These pumps are not designed to be used with
abrasive, solid containing, explosive and corrosive liquids.

4.1 Temperatures
Ambient temperature: 0°C to +50°C
WARNING: If ambient temperature is above +50 degrees C,
or if the pump is located at elevations more than 1,000 me-
ters above sea level, the motor’s output must be decreased
to compensate for less effective cooling, and may have to be
replaced with a larger motor.
Liquid temperature: -15°C to +120°C
4.2 Maximum operating pressure
See appendix
4.3 Minimum inlet pressure-NPSH
To avoid cavitation, make sure that there is a minimum pres-
sure on the suction side of the pump.
NPSH

: Net Positive Suction Head Available
— The net positive suction head available is a function of the
pump suction system.
