The centrifugal pump is suitable for applications where it is required to transport a liquid quickly and continuously. However, before choosing it, it's essential to evaluate all the operating conditions:
- Processed Fluid: A centrifugal pump is a high-performance but delicate machine. Therefore, the working liquid should have low to medium viscosity and a specific weight up to 1.9 kg/L. Higher values would excessively strain the mechanical parts and the impeller, and the operation of the motor would be compromised due to out-of-range absorptions. Despite the open impeller, which allows the passage of dirty liquids, it's not advisable to suction liquids with long solid particles and a diameter larger than one millimeter. Using a centrifugal pump for overly corrosive or very dirty fluids risks damaging the impeller or mechanical seals.
- Temperature: Fluimac centrifugal pumps can be used in a range between -5°C and +65°C if made of polypropylene, otherwise between -20°C and +95°C if the centrifugal pump is made of PVDF. It's important that the fluid always remains in a liquid state.
- Working Conditions: Each centrifugal pump is associated with a specific characteristic curve that shows the head [m] the machine can reach given a certain flow rate [m3/h]. Knowing the conditions of your system before choosing a centrifugal pump prevents the risk of inadequate performance and damage to the system and the machine.
- Configuration: Fluimac offers both horizontal and vertical centrifugal pumps. The former are placed externally to the extraction tank, below the free level of the fluid, with the axis parallel to the ground; the latter are partially submerged in the fluid and positioned with a vertical axis relative to the ground.
- Motor Power Supply: Fluimac centrifugal pumps are designed primarily for electric motor operation, but configurations with pneumatic motors are possible. The system must be suitable and sized to ensure continuous power supply.
