The mining industry fluctuates by the prices of the items you’re mining. As you know, that means that opportunities come up fast. If you’ve ever experienced a jump in price for gold or copper, you know how important it is to act quickly. Being able to react requires durable, reliable pumps to remove ground water from your mine or quarry. As mines are further developed, you need higher heads to keep the site dry and allow for further development. Not all high head submersible pumps are the same. These are the three main considerations to finding the right high head pump.
High Head Submersible Pump Conditions
In certain mining applications, you can only rely on a high head dewatering pump to meet the desired conditions. This is the case when you require heads between 150’-350’ total dynamic head (TDH). TDH is the combination of the static lift (the elevation difference between the water level and the end of the pump discharge piping) and friction loss through the piping system.
High head pumps help you with high static lift needs or when you have a long run of pipe with friction loss. For example, if you have one mile of 4” piping, the friction loss would be 320’ at 300 GPM. You need a high head pump capable of pushing the water all the way through the pipe with enough force to account for that friction loss.
Heavy Duty Construction
In most cases, you not only need a pump that can reach the heights you need, you also need to handle some abrasive particles. The reality is that truly clean water in mines is rare. There is always some kind of stone or coal dust mixed into the liquid. This can quickly wear out general dewatering pumps that aren’t suited for these applications. Hard metal high head pumps stand up to these abrasives.
The hard metal components, like high chrome iron impellers and hardened wear rings and volutes, withstand abrasive materials better than cast iron and rubber-lined pumps. This prolongs the pumps’ service lives with minimal maintenance and repair needs. Many customers also use vertical turbine pumps, but vertical turbine pump designs use very tight tolerances, and are typically meant for clean water applications. Abrasives easily damage them and shorten their lifespan.
High chrome agitators keep the bottom of the pit clean by mixing solids within the liquid to keep from settling and causing clogs. Agitators are not available for most high head pumps. BJM Pumps offers the only high head dewatering pump with an optional agitator.
BJM’s high head dewatering pumps also feature a top discharge design. This design allows the pumped liquid to cool the pump so you can pump down to extremely low levels without overheating the motor. This is in contrast to side discharge pumps that leave up to three feet of liquid because it must remain submerged to avoid overheating.
Short Lead Times
When your pump wears out and fails, you need to replace it fast. Lost production due to downtime is expensive, costing up to $100,000 PER HOUR! Most of you don’t have the time or budget to wait for replacement pumps with long lead times. If you’ve had to play the waiting game in the past, you know that puts you far behind schedule.
Nobody understands that better than BJM Pumps. With our strong network of distributors combined with our fast factory deliveries, we get you back up and running fast. We’re known for our short lead times of two weeks or less, including for our new KHD and KHH high head dewatering pumps. Compare that to the industry average lead time of six to eight weeks…some manufacturers are even higher at 12-14 weeks!
Since 1983, BJM Pumps and our expertly-trained distributors have designed the solutions you need for the mining industry. Adding our new high head dewatering pumps was result of feedback from customers like you. With these new pumps, BJM offers the full range of pumps needed for all mining applications. Customers receive unparalleled service from specification through installation and continued support throughout the life of the pump. Contact us at 860-399-5937 or request more information.
