Select a number to investigate the pumping challenges in the Ready-Mix industry
Pumps play a vital part in producing ready-mix concrete. The high-pressure, competitive nature of this industry puts a premium on maximising production and avoiding downtime. Delays due to a pump taken out for repair can lead to problems such as a wedge pit becoming inoperable, mixing trucks not being cleaned and batching plants coming to a halt.
It is vital to select the correct pump for the application as this will give the most production for the best wear life. Here’s a brief guide to the main applications found on a ready-mix site and our recommended pump solutions.
Main Water Feed
As this is usually clean water, you can use a high-efficiency water pump to give you the required pressure and volume to feed your plant. It is better to over-specify on this pump as this supply is crucial to production. Lowara centrifugal pumps (page 10) are ideal for this application. Please note these pumps are not suitable for recycled water feed.
These pumps are used to add liquid additives to the concrete being mixed in the batching plant. Many sites use Mono pumps or equivalent small electric gear pumps. Spares for these pumps are also readily available.
Spray Bars and Wash Down
This application requires reasonably high pressure, the ideal pump is vertical multistage. It is important to note that using the pump for more than one application has a significant impact on performance; ideally use a separate pump for wash down and spray bars. As these pumps are designed for clean water only, filter as much as possible. If pumping dirty water, you should consider the Audex AW range.
Wedge Pit Pumping
This application involves pumping dirty water or slurry, containing aggregate particles and fibres. The Audex AW range are ideal for this, being designed for solids handling, having a robust construction and an agitator to prevent clogging. They also have strainers that can handle small solids, and high-head versions are available. Also consider JS Pumps or Varisco for this application.
Recycled Water Feed Back to Plant
As this water can be dirty, and could possibly contain solids, it is important to use a pump designed for solids-handling and clean water pumps will not last in this application. Audex AW, JS Pumps, and Varisco Pumps are suitable. Attention should be taken to the condition of the fluid in the storage tank (may need agitating to stop it getting too thick).
