For SEEPEX’s next generation of pumps, the designer leans on more than 50 years of engineering to deliver mining, wastewater, chemical and industrial applications.
SEEPEX’s latest pump innovation is Smart Joint Access (SJA), which is engineered for the reliable and precise transfer of abrasive, corrosive and media in mining and construction.
Designed for rock blasting, SJA pumps feature a large inspection opening for quick joint checks, a small footprint for mobile or skid-mounted installations, and flexible drive and material options to ensure consistent performance and uptime.
“Operators can inspect joints quickly and rely on precise pumping of shear-sensitive and abrasive emulsions,” SEEPEX global business development manager mining Magalie Levray said. “This is particularly critical in rock blasting, where every borehole counts for productivity.”
Rock blasting is essential for extracting hard rock and shaping safe excavation profiles in mining and construction. Accurate and consistent loading of explosive emulsions helps to ensure controlled fragmentation and maximise productivity.
As efficiency is consistently at the forefront of SEEPEX’s innovations, SJA is designed for inspection-friendly operations. The large opening in the suction housing provides direct visual access to both joints, enabling rapid pre-operation checks while maintaining high operational reliability. Technicians can assess joint condition in minutes, supporting continuous, reliable operation.
The equipment is engineered with a small footprint that fits easily into truck-mounted mobile units, skid-mounted systems and factory installations. It offers flexible drive options, accommodating compact hydraulic and electric drive configurations.
The system is built for high hydraulic efficiency, utilising a low-displacement design that significantly reduces oil requirements and supports a low total cost of ownership. In addition, the equal wall stator design delivers high pressure without expanding the unit’s compact profile.
Constructed for material flexibility, the pumps are available in stainless steel or standard steel and feature chrome-plated rotors paired with stators made from nitrile butadiene rubber (NBR), ethylene propylene diene monomer (EPDM) or fluoro elastomer (FKM).
Operators benefit from shorter inspection cycles, reliable dosing, seamless integration, and fast delivery through framework agreements, maintaining uptime in critical rock blasting processes.
The fact operators can visually assess both joints on SJA products without disassembly enables immediate verification of pump readiness before blast hole loading. This reduces downtime, preserves product integrity, and ensures accurate, consistent emulsion transfer with uniform dosing across multiple bore holes.
The combination of compact integration, flexible drives and progressive cavity pump technology ensures continuous, reliable operation even in limited-space, high-pressure environments.
Pumps with SJA support mobile manufacturing units at large open-pit iron ore and gold mines. Rapid pre-operation inspections enable consistent emulsion dosing for blast hole loading.
With equal wall stator design and compact hydraulic drives, pumps integrate easily on mobile units navigating complex mine layouts, maintaining stable, controlled pumping of viscous, shear-sensitive and abrasive emulsions. SJA inspection openings on both sides of the suction housing reduce installation complexity and costs.
“Using Smart Joint Access, we complete joint inspections in minutes, keeping blasting operations on schedule,” a mine operator said. “Smooth flow preserves chemical properties, reduces usage, and improves fragmentation.”
