RELIEF
The pump by-pass is not intended to be a metering or flow
control device. Its main purpose is to function as a pressure relief
when the desired set point is exceeded. Overheating can occur within 5-10 minutes if the discharge line is completely shut off for extended periods.
Reversing rotation reverses the “IN” and “OUT” ports and the
location of the by-pass ports have to be reversed. The by-pass valve
is factory set at 115 psi/1300RPM. To increase the setpoint, turn the
