Slurry Pumps: The solution

Successfully extending the working life of a slurry pump requires a three-pronged approach that addresses the following:

1. Effective monitoring
2. The right mechanical packing, seals and lubrication
3. Protecting the internal workings of the pump

The right solution can dramatically extend the working life of a slurry pump and reduce the need for costly maintenance shutdowns. Sealing experts Chesterton has brought innovative solutions to market designed to be used in both isolation and combination to create a powerful solution to each challenge.

1. Effective monitoring with Chesterton Connect

Imagine a device that could monitor equipment process and operating conditions. Now imagine that it could do so remotely and in harsh conditions. Finally, imagine the ability to connect to multiple sensors, receive alerts, and monitor the data via a simple app.

This is not a figment of imagination, nor is it a prototype. This is a proven and new-to-market product known as Chesterton Connect – simplified equipment and process monitoring unit for pumps and sealing systems.

Not only is it easy to install, but this data acquisition tool allows users to accurately monitor vibrations, surface temperature, process temperature and process pressure. Using Bluetooth technology, undesirable events can be far better understood, leading to effective maintenance and preventative actions to extend longevity.

Once we understand that slurry pump failure is almost always down to a lack of knowledge about the pump’s health and working conditions, the effective provision of the other two aspects becomes easier to manage.

2. The right lubrication, mechanical packaging and seals

The choice of grease is an essential element of slurry pump longevity. Ensuring that it can cope with extreme pressure and the corrosive elements associated with slurry is essential. Chesterton has designed a range of greases that provide outstanding performance in various conditions，both of which provide exceptional lubrication capabilities.

However, applying good grease at the right amount at the right time has always been a challenge.  This innovative solution has been pivotal in solving many unnecessary slurry pump failures. Indeed, such is its success that the Lubri-Cup/Chesterton Grease combination has effectively extended slurry pump lifespan by over 100%, as shown in this case study.

When it comes to mechanical packing and mechanical seals, the key to slurry pump health is to eliminate expensive external seal flushes and withstand the harsh environment. 

Whether used in isolation or combination with any of the above slurry pump measures, these environment-specific seal remedies have provided a revolutionary way to improve slurry pump performance.

Of course, we can’t ignore the corrosive effect that slurry has on the internal workings of the pump. Chesterton’s ingenious coating has been formulated to dramatically negate the effect of dry, coarse particle erosion and sliding wear abrasion.
