5.2 Starting up the product
After installing the product, do the following:
1. Open all isolating valves. Make sure that the water supply is
sufficient on the inlet side of the pump.
2. Turn on the power supply to the pump, and the pump will start.
If there is a suction lift, it can take up to five minutes before the
pump delivers water. This period depends on the length and
diameter of the inlet pipe.
3. Open the tapping point that is highest or furthest away from the
pump to let out air trapped in the system.
4. When water flows through the tapping point, close it.
5. Startup is completed, and the pump is ready for operation.
5.2.1 Shaft seal run-in
The shaft seal faces are lubricated by the pumped liquid. A slight
leakage from the shaft seal of up to 10 ml per day or 8 to 10 drops
per hour may occur. Under normal conditions, the leaking liquid will
evaporate. As a result, no leakage will be detected.
When the pump is started for the first time, or when the shaft seal
has been replaced, a certain run-in period is required before the
leakage is reduced to an acceptable level. The time required for this
depends on the operating conditions, that is, every time the
operating conditions change, a new run-in period will be started.
Leaking liquid will drain through the drain holes in the motor flange.
Install the product in such a way that leakage cannot cause
undesirable collateral damage.
6. Product introduction
JP PS
Grundfos JP PS pumps are designed for domestic use and ensure
a constant supply of clean water to households and gardens as well
as light commercial applications.
JP PS is a self-priming, single-stage centrifugal jet pump. The jet
pump has excellent suction capacity and is designed for long and
trouble-free operation. The built-in ejector with guide vanes ensures
optimum self-priming properties. JP PS is small and compact. The
pump housing is made of stainless steel.
JP PS pumps have a built-in pressure switch. The pressure control
allows the pump to start and stop automatically according to
demand when you open the tap.
