2.3.2 Liquid temperature
32-104 °F (0-40 °C).
For non-explosion-proof pumps, a temperature of
up to 140 °F (60 °C) is permissible for short
periods (maximum 3 minutes).
2.3.3 Ambient temperature
32 °F to +104 °F (0 to +40 °C).
Explosion-proof pumps must never
FM
pump liquids at a temperature higher
than +104 °F (+40 °C).
2.3.4 Density and viscosity of pumped liquid
When pumping liquids with a density and/or a
kinematic viscosity higher than water, use motors
with correspondingly higher outputs.
Keep a minimum flow velocity to
avoid sedimentation in the piping
system.
Flow
Recommended flow velocities:
velocity
in vertical pipes: 2.3 ft/s (0.7 m/s)
in horizontal pipes: 3.3 ft/s (1.0
m/s).
Free
2" - 4" (50-100 mm), depending on
spherical
pump size.
passage
Operating
Maximum 20 starts per hour.

2.4 Identification
2.4.1 Nameplate
The nameplate states the operating data and
approvals applying to the pump. The nameplate is
fitted to the side of the stator housing close to the
cable entry.
Fix the extra nameplate supplied with the pump to
the cable end in the controller.
