SQFlex
Curve conditions
The SQFlex Solar performance range shown on page 3
is based on:
• solar radiation on a tilted surface
• H
T
= 6 kWh/m
2
per day
• 20° tilt angle
• ambient temperature: +86°F
• 20° northern latitude
• panel voltage: 120 VDC
• an 11 hour standard solar day.
The SQFlex Wind performance range shown on page 3
is based on:
• average wind speed
• calculations according to Weibull’s factor k = 2
• continuous operation over 24 hours.
The performance charts on pages 24 to 27 are based
on the following guidelines:
• All curves show mean values.
• The curves must not be used as guarantee curves.
• Typical deviation: +/–15%.
• The measurements were made at a water tempera-
ture of +86°F.
• The curves apply to a kinematic viscosity of 1 mm
2
/
s (1 cSt). If the pump is used for liquids with a vis-
cosity higher than that of water, this will reduce the
head and increase the power consumption.
• The performance curves are inclusive of inlet and
valve losses at the actual speed.
• Supply to pump: 120 VDC.
Wiring diagram for pump
Connection of the MSF motor to the power supply must
be done according to the wiring diagram shown below.
As the intelligent motor electronics can handle both
connection possibilities, it makes no difference how the
wires "+" and "–" or "N" and L" are connected.
