Liquid temperature
0 °C to + 40 °C.
For short periods (maximum 3 minutes) a temperature of up to
+60 °C is permissible (non-Ex versions only).
Ambient temperature
For non-explosion proof pumps, the ambient temperature may
exceed +40 °C for a short period (max. 3 minutes).
Density and viscosity of pumped liquid
When pumping liquids with a density and/or a kinematic viscosity
higher than that of water, use motors with correspondingly higher
outputs.
Flow velocity
It is advisable to keep a minimum flow velocity to avoid
sedimentations in the piping system. Recommended flow
velocities:
• in vertical pipes: 1.0 m/s
• in horizontal pipes: 0.7 m/s
Maximum solids size
From 50 to 100 mm, depending on pump size.
Operating mode
Maximum 20 starts per hour.
3. Delivery and handling
The pump may be transported and stored in a vertical or
horizontal position. Make sure that it cannot roll or fall over.
3.1 Transportation
All lifting equipment must be rated for the purpose and checked
for damage before any attempts to lift the pump. The lifting
equipment rating must under no circumstances be exceeded.
The pump weight is stated on the pump nameplate.
3.2 Storage
During long periods of storage, the pump must be protected
against moisture and heat.
Storage temperature: -30 °C to +60 °C
If the pump has been in use, the oil should be changed before
storage.
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 condition of the shaft
seal, O-rings, oil and the cable entry.
4. Identification
4.1 Nameplate
The nameplate states the operating data and approvals applying
to the pump. The nameplate is fitted to the side of the motor
housing close to the cable entry.
Fix the extra nameplate supplied with the pump to the cable end
in the control cabinet.

Warning
Explosion-proof pumps must never pump liquids
of a temperature higher than +40 °C.
Warning
For explosion-proof pumps, the ambient
temperature on the installation site must be in
the range from -20 °C to +40 °C.
For explosion-proof pumps with WIO sensor, the
ambient temperature at the installation site must
be in the range from 0 °C to +40 °C.
Warning
Always lift the pump by its lifting bracket or by
means of a fork-lift truck if the pump is fixed on a
pallet. Never lift the pump by means of the motor
cable or the hose/pipe.
Warning
If the pumps are stored for more than one year or
it takes a long time before it is put into operation
after the installation, the impeller must be turned
at least once a month.
