2.2 Operating conditions

2.2.1 pH-value
APG pumps in permanent installations can cope with
pH-values ranging from 4 to 10.
2.2.2 Liquid temperature
Liquid temperature: 0 °C to +40 °C.
For short periods up to +60 °C.
2.2.3 Density of pumped liquid
Maximum density of pumped liquid: 1100 kg/m
2.2.4 Installation depth
Maximum 10 metres below liquid level.
2.2.5 Level of pumped liquid
The lowest stop level must always be above the top
of the pump housing.
2.2.6 Operation
Maximum 15 starts per hour.
The pumps are designed for intermittent
Note
operation only.

2.3 Sound pressure level

The sound pressure level of the pump is lower than
the limiting values stated in the EC Council Directive
98/37/EEC relating to machinery.

3. Safety

Warning
Pump installation in wells must be carried
out by specially trained persons.

4. Transportation and storage

The pump may be transported and stored in a
vertical or horizontal position. Make sure that it
cannot roll or fall over.
Always lift the pump by its carrying handle, never by
the motor cable or the hose/pipe.
For long periods of storage, the pump must be
protected against moisture and heat.
After a long period of storage, the pump should be
inspected before it is put into operation. Make sure
that the impeller can rotate freely. Pay special
attention to the shaft seals and the cable entry.
