Pump Efficiency

At Pumpteq we look at all types of pump efficiency from our client’s systems to the individual pumps. We understand that efficiency comes from Life Cycle Costs, Operation Costs, Downtime, Repairs and Maintenance.
We recognize our clients can’t afford downtime and loss of production so we offer new and innovative solutions to ensure they achieve the best efficiency from their pumps.

Client feedback informs us that common areas of concern with regards to efficiency are both mechanical and hydraulic losses.

Mechanical friction losses can be caused by the pump coupling type or driven parts such as bearings, shaft seals and gears depending on your pump type.

The amount of loss will vary, for example rotational speed and pressure will have an effect. Therefore there would be an increased power demand, consequently reducing pump efficiency. These losses may also be known as parasitic losses.

Hydraulic losses occur along the pumps fluid path. These can transpire due to friction or change in fluid direction and velocity.

For example, some of the losses can be caused by flow friction, recirculation losses and leakage.

Flow Friction is where contact is made with fluid and interior surfaces. This cause’s a pressure low, which reduces performance, which in turn reduces efficiency.

Recirculation loss occurs around the main flow which is high velocity. Where recirculation occurs, also known as eddies, these have close to zero velocity. This causes a loss of flow velocity, which in turn reduces performance and efficiency.

Leakage loss is due to gaps between rotating and fixed parts of the pump. One of the most common is the increased gap between the impeller wear ring and case wear ring, this kind of loss reduces flow throughout the fluid path.

The above are only a few of the multitude of hydraulic and mechanical losses that can occur. We look at all losses that can affect your pump efficiency, not just the above mentioned.

To gain optimum life from any pump you need to ensure you maintain the pump with regular and effective servicing. It can be more cost effective to consider upgrades and planned overhauls or change materials of parts, than carrying out frequent repairs.
