Centrifugal pumps are capable of providing efficiencies up to 93 percent and even the smallest pumps have an efficiency that falls into the 50 to 70 percent range. Centrifugal water pumps convert mechanical energy into hydraulic energy (flow, velocity and pressure), while a centrifugal motor i.e., AC motor converts electrical energy into mechanical energy.
Countless nitty-gritty details and factors are carefully monitored to ensure that the efficiency of centrifugal pumps is maintained and increased if possible. Let’s take a look at the methods followed to up the efficiency of the pumps:
- By employing high specific speed
As pump’s efficiency is directly dependent on the specific speed, the higher the latter is the better the efficiency is, resulting in energy conservation
- Using good wear ring with proper clearance
Though even a well-designed pump comes with a diametral clearance of 0.2 to 0.4%, as long as it remains between 0.6 to 0.8 % there is no issue. But the moment it starts increasing beyond this limit, the efficiency of the pump drops. As pumps continuously wear with time, the best option here is to continuously switch the wear ring, having good quality.
- Avoid running one pump instead of two
It is often seen in many installations that two pumps are operating simultaneously even when the required supply can be managed by a single pump. This not only leads to wastage of energy but also limits the pumps to work at their full efficiency.
- Maintaining good insulation and ensuring that there is steam tracing in the suction line of the pump
An often neglected yet necessary arrangement, insulation and steam tracing help in diminishing the damage done by a liquid’s viscosity which causes fluid friction and disc friction. The higher the viscosity of the liquid, the lesser is the pump’s efficiency
- Selecting a pump ideal for its application
Every pump generates different amounts of flow at different pressures, so often it happens that a pump, improper for its application, is chosen. It’s either too large or too small and ends up reducing the system performance as it results in inadequate flow.
