Installation
P1
P2a
Do not expose the pump to higher pressures than
which the pump is suitable according to the curve.
Prevent dirt particles in the medium (only clean
filtered medium allowed)
With volatile, flammable liquids only a clean, filtered
medium may be used)
P2b Prevent dirt particles larger than the dirt passage of
the rotor from arriving in the suction line and pump.
P3 Make sure that the pump (unit) is mechanically well
shielded while operating.
P4 Make sure that pump is installed without any
stresses.
Including coupling and E-motor.
P5 Ensure the correct coolant for mechanical shaft seal.
P6 Ensure the correct coolant and temperature for the
medium to be pumped.
P7 Make sure the rotation direction arrow is present.
P8 Connection between pump and ground (earthing).
P9 Ensure the good alignment of the pump and drive
gear.
P10 Ensure the good fitting of the coupling on the pump
shaft and drive gear.
Startup/Use
G1 Prevent pump being exposed to temperatures below
freezing point if it is filled with liquid.
G2 Make sure that liquid supply to the pump is smooth
and oxygen-free.
G3 Ensure the correct direction of rotation.
G5 Prevent the pump for dry running.
G6 Make sure the pump does not pump against a closed
valve.
G8 Make sure that the pump is filled with liquid at the
correct temperature.
G9 Make sure that the mechanical shaft seal
cooling/lubrication is in good working order.
G10 Ensure sufficient coolant
G11 Prevent the sudden closing of valves so a water
shock originates.
