Factors That Affect Maintenance Time

Maintenance is an integral part of selecting well pumps and other types of water pumps such as submersible pumps, centrifugal pump, hydraulic pump and gear pump. This is because frequent maintenance is not only costly, it is also extremely inconvenient for pump owners. Hence, it is important to purchase water pumps from high quality manufacturers such as Grundfos, this is because Grundfos pumps are able to operate for long periods of time with little or no maintenance. When it comes to duration and maintenance there are two important factors to consider:

• Mean Time Between Failure (MTBF)
• Downtime costs

MTBF refers to the time between when the pump is working and when it breaks down, while downtime costs refers to the total time taken for fixing the broken pump. The objective of Grundfos pumps manufacturers, is to extend the MTBF time as much as possible and to keep the downtime costs as short as possible. This is because the longer MTBF is, the less time is taken for repairs, while if downtime costs are short, it means repairs can be done quickly and efficiently. Reducing downtime costs depends on a number of costs such as having the best personnel and the best plan for fixing broken down well pumps.

The Importance Of Casing And Other Factors In Grundfos Pumps

Casing is another important factor of maintenance, pump manufacturers tend to use several different materials for casing in the creation of well pumps. These materials include cast iron, graphite and stainless steel alloys, selecting the right material is very important because pump manufacturers do not select material for casing based on strength alone. For example, stainless steel is a hard material able to absorb impact, but it doesn’t always mean it should be used in pump manufacturing, for example, cast iron is not hard as stainless steel, but it is very ductile and can be used in different pumps.

Grundfos manufacturers use a number of methods to prolong MTBF and reduce downtime costs, for example the right pump parts are chosen to manufacture Grundfos pumps. The right pump parts, refer to components or parts of the pump that use the right amount of power does not put any excess load on the pump parts and components. There are other factors that affect maintenance time, such as the ability to replace case rings quickly and easily and 'back pullout' which refers to the ability to remove the rotating assembly without disrupting the pipe.
