2. HANDLING
Read these instructions carefully before beginning installation.
Lift and handle these pumps carefully. VPC & VPS series are
vertical multi-stage non-self priming pumps coupled with
standard electric motors. This manual applies to standard ver-
sion pumps and for standard applications. Contact your supplier
or the factory for information about special pump versions and
applications.
3. APPLICATIONS

4. TECHNICAL DATA
4.1 Temperatures
Ambient temperature: 32 F to +104 F
If ambient temperatures are above +104° F
or if the pump is located at elevations more
than 3,000 feet above sea level, the motor's
output must be decreased to compensate
for less effective cooling, and may have to
be replaced with a stronger motor.
Liquid temperature: -5 F to +248 F
4.2 Maximum operating pressure
Refer to page 8
4.3 Minimum inlet pressure-NPSH
To avoid cavitation, make sure that there is a minimum pressure
on the suction side of the pump.
NPSHA: Net Positive Suction head Available
The net positive suction head available is a function of the pump
suction system.
NPSHR: Net Positive Suction head required
The net positive suction head required is a function of the pump
design at the operating point on the pump performance curve.
