SEEPEX BN Pumps Boost Rock Blasting Efficiency

2026-02-18

SEEPEX has introduced its BN pumps equipped with Smart Joint Access (SJA), engineered for the precise transfer of abrasive, corrosive and chemical media in mining and construction applications. Designed specifically for rock blasting operations, the pumps enable faster inspection, improved uptime and consistent emulsion dosing across bore holes.

Rock blasting plays a critical role in hard rock extraction and controlled excavation in mining, tunnelling and quarrying. Accurate pumping of explosive emulsions is essential to ensure safe fragmentation, protect personnel and maintain productivity. Even minor deviations in flow can affect blast performance and operational timelines.

The Smart Joint Access feature incorporates a large inspection opening within the suction housing, allowing direct access to both joints without disassembly. This enables rapid pre-operation checks and supports routine maintenance, reducing downtime and strengthening operational reliability.

The BN pumps are designed with a compact footprint, making them suitable for truck-mounted mobile units, skid-mounted systems and fixed plant installations. Operators can choose between compact hydraulic drives or electric drive configurations, depending on site requirements.

Additional features include a low-displacement hydraulic design that reduces oil consumption and supports lower total cost of ownership. The equal wall stator design delivers high-pressure performance within a compact structure, while material options such as stainless steel or steel housings, chrome-plated rotors and stators in NBR, EPDM or FKM provide flexibility for demanding environments.

A leading explosives provider recently deployed BN pumps with SJA in open-pit and underground operations. The upgrade shortened inspection cycles and enabled quicker return of mobile units to active blasting schedules. Direct joint access supported consistent emulsion transfer and reduced downtime linked to joint-related issues.

The pumps are suited for mining, civil works, dam construction and other sectors requiring reliable handling of abrasive or chemical media. By combining progressive cavity pump technology with inspection-ready design, SEEPEX aims to enhance safety, efficiency and reliability in high-pressure, space-constrained environments.
