As a concrete contractor, you should use concrete pump equipment that is well-maintained so as to ensure maximum possible uptime on-site. If you are a new entrant in the concrete construction business, maintaining your concrete pumps in-house may be quite a costly affair. Therefore, renting the equipment may make better financial sense.

Here is a look at some typical problems that your concrete pump hire company can help you solve when you go for the rental option.

Blockage in the pump line

One of the major issues that concrete pump maintenance crews must constantly be aware of is the possibility of blockage in the pump line. Whenever something is being transported via a pipeline, blockage is always a risk. This can happen due to a number of different reasons, including mix anomalies, system-related problems, and operator errors.

An increase in pump line resistance, for instance, as indicated on the pressure gauge of pump, is a sure-fire sign of blockage. The most likely cause of blockage is a faulty reducer. The reducer is the component that connects the pump to the line system. A rapid increase in pressure prior to the clog indicates the problem is most probably in the pump area. A slow rise in pressure, on the other hand, is suggestive of a clog further down the line, close to the delivery end. 

Whatever the case, technicians from your equipment rental company will inspect the entire system, locate the source of the blockage and clear it before it can lead to complete system failure. 

Cavitation

Cavitation is a common problem with water pumps, but it can also occur in concrete pumps. Concrete pump cavitation normally arises because water is part of the concrete mix, and the mix is pumped in liquid form. It typically takes place when continuing changes in temperature and pressure within the pump system leads to formation of air bubbles in the concrete mix, and the bubbles can't escape. 

Your equipment rental company's maintenance technicians will constantly monitor the temperature and pressure within the pump system, as they tend to fluctuate drastically during the day. If left unattended, cavitation can damage the mechanical components of your pump, but also reduce the efficiency of concrete pumping jobs.

By keeping the above-highlighted issues, as well as any other concrete pump problems that may crop up in check, the maintenance crew from your equipment provider will ensure you get reliable service from your equipment for the entire duration of use.
