The 5th Generation MP HPU is a testament to Metso's commitment to listening to customer feedback and addressing real-world challenges. With modernized components, remote monitoring capabilities and sustainable design updates, the newest generation revolutionizes crushing operations and ensures efficient, safe and continuous production. Let’s dive into the details to discover how Metso's customer-centric approach has led to groundbreaking improvements in mining equipment maintenance.

Critical equipment is in constant use and in need of regular upkeep at mines around the globe. Planning around scheduled shutdowns is crucial to ensure the equipment keeps producing. However, due to production schedules and operational pressure, maintenance can be deferred, leading to critical equipment being overlooked. This can eventually result in equipment failure, which impacts production. Unplanned maintenance can also halt downstream processes, further affecting throughput. 

The hydraulic power unit (HPU) is essential for your crushing operation as it controls the pump and motor group that pressurizes and depressurizes a crusher’s hydraulic circuits, allowing for adjustment of the crusher settings and maintenance on the crusher components. Although critical, it is often one of the pieces of equipment that gets overlooked. Over the years, contamination, wear and age result in failures and leaks. As the power unit ages, finding spare parts or replacements becomes increasingly difficult. Constant improvements in electronics design often require a search for replacements or a full update of components to align with modern offerings. This can be frustrating and cause unplanned downtime and lost production if not addressed. This challenge is becoming more critical as knowledgeable crusher experts retire from the industry, making it harder to find qualified replacements. Metso has collaborated with suppliers, customers and support staff to address these challenges by introducing a 5th Generation MP HPU with new functions to increase reliability, reduce maintenance and improve safety. 

Modernization 

Industry trends are moving away from hands-on maintenance and operation to meet operational goals of constantly higher throughput. Crusher stations are increasingly monitored remotely using I/O solutions for complete remote monitoring and control. This demand now extends to lube and hydraulic systems. Metso has improved capabilities in this area, offering ready-to-integrate HPUs with Flex I/O connections for easy PLC control integration. Metso still supports traditional PLC inclusion but offers flexibility to choose the best supply option for your operation. 

While transducers for monitoring HPUs have been used for years, another often neglected solution is monitoring through a controls system. Metso has created an external transducer cabinet for quick, easy confirmation without opening the HPU. External gage clusters have been moved to protected locations to prevent damage and allow quick and easy monitoring during maintenance operations. These changes modernize maintenance and ensure the longevity of your HPU in challenging conditions.  

Keeping hydraulics clean and free of contamination is crucial for continued operation. Crusher applications often face dust and dirt ingress, causing critical damage. Sealed doors and locking handles prevent contaminants from entering the cabinet, extending the life of components like the valve block, pump and motor assembly. The external transducer compartment reduces the need to enter the HPU, further keeping internals clean. An external oil filtration system can also be easily added to the unit, ensuring oil remains in top condition. These changes improve maintenance practices and modernize hydraulics to ensure maximum performance from crushing operations. 

Sustainability 

With growing resource demand, sustainability initiatives are critical to mine planning. Improvements that lower environmental impacts are now a requirement, and no longer just preferable. Updates for hydraulic power units aim to meet our customers’ sustainability goals. Pump and motor groups are streamlined to a single size, reducing the spare stock needed onsite there by lowering CO2 emissions from transportation and building spare components. In addition, the unified pump and motor group pressurizes hydraulic circuits faster for MP800 and MP1000 crushers. 

Manifold block maintenance has always been challenging, even during scheduled downtime. Crews often replace the entire manifold block instead of repairing it, leading to increased environmental impact and waste. New design updates include repair kits for each manifold block function, with balloon drawings and QR codes providing repair teams with the necessary knowledge and parts. Onsite crews can now maintain the manifold block without sending it offsite for a complete rebuild. This reduces the number of parts needed and helps mine sites improve uptime and meet their sustainability targets. 

Safety 

After gathering global feedback from Nordberg™ crusher users, common concerns about HPU maintenance emerged. One major issue was access to the units for maintenance. Installations often required teams to crouch and lift unwieldy parts, risking strains or injury. Updates to the 5th Generation MP HPU provide the solution, including a hinged top for easier access to the manifold block and pump and motor group. Removable front bracing has also been developed to further enhance access into the HPU. These updates enable faster, safer repairs. Quick, reliable and safe service is essential for profitable crushing operations. 

Reducing strain injuries at mine sites is also a common concern for Metso customers. In response, legs have been added to the base of the unit, with 12 and 18-inch extension options to bring the work closer to staff. Accumulator charging is easier with remote charging ports accessible by opening the front panel on the HPU. Tank cleanout is manageable through a side cleanout port, preventing crews from leaning into the unit to clean old or dirty oil. Redundant HPU accumulators also provide flexible repair options, helping to reduce your repair crew’s risk of injury at site.  

A continuous commitment to customer success 

The 5th Generation MP HPU by Metso is a game-changer for mining operations. With modernized components, remote monitoring capabilities, and sustainable design updates, this new HPU ensures efficient, safe and continuous production.
