Operating conditions
FX RANGE pumps are suitable for continuous operation always immersed in the pumped liquid. The FX RANGE pumps allow operation
with the motor NOT IMMERSED for short periods (10min).
pH value: 6.5-12 (Warning: indicative range, the pH value alone is not exhaustive in defining the aggressiveness of the pumped liquid)
Temperature of the operating liquid: 0 °C to +50 °C (non-Ex versions only).
For short periods a temperature of up to +60 °C is permissible (non-Ex versions only).
Explosion-proof pumps must never pump liquids of a temperature higher than +40 °C.
Ambient temperature
For non-explosion proof pumps, the ambient temperature may 40 °C for a short period.
For explosion-proof pumps, the ambient temperature on the installation site must be in the range from 0°C + 40 °C.
Density and viscosity of the pumped liquid: viscosity and density comparable to those of water.
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
Operating mode
Maximum 20 starts per hour.
FOR FURTHER LIMITATIONS OF THE OPERATING RANGE, REFER TO THE IDENTIFICATION PLATE.
3. DELIVERY AND HANDLING
3.1
Transportation
Before lifting the pump, check that the tools and equipment used for handling, lifting and lowering it into the sinkhole
are suitable for the weight to be lifted, efficient and complying with the applicable safety laws.
The weight of the pump is declared on the pump identification plate and on the label on the packaging.
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.
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.
The impeller may have sharp edges – wear protective gloves.
If stored outside the limits indicated, pay particular attention to the conditions of the mechanical seal, the O-rings, the oil and the cable gland.
