Inspection-friendly progressive cavity pump design
SEEPEX has introduced Smart Joint Access, a new inspection-friendly pump design developed for demanding industrial environments where uptime and reliability are critical.
Integrated into the company’s BN progressive cavity pump, Smart Joint Access (SJA) combines a compact footprint with direct visual access to both joints via a large opening in the suction housing. This enables efficient condition assessment while ensuring precise handling of shear-sensitive, abrasive, or corrosive media.
Designed for space-constrained installations, the BN pump with SJA is particularly well-suited for mobile manufacturing units, underground installations, and skid-mounted or stationary systems. Flexible integration and low-energy operation support reliable performance in applications where downtime is not an option.
Rock blasting
Rock blasting plays a central role in mining, tunnelling, and construction, requiring accurate and consistent loading of explosive emulsions to achieve controlled fragmentation and maintain productivity. In these operations, deviations in pumping performance can lead to blast inconsistencies, rework, or delays.
SEEPEX BN pumps with SJA are designed to meet these operational demands. Quick and easy access to the joints supports reliable emulsion transfer and precise dosing, making the pump well-suited to blast hole loading and other critical chemical handling processes.
“Smart Joint Access enhances availability and operational efficiency for our customers,” said Magalie Levray, Global Business Development Manager Mining at SEEPEX. “Operators gain direct access to the joints through the large inspection opening, reduce downtime, and rely on consistent, precise pumping of viscous, shear-sensitive, and abrasive emulsions. In rock blasting, where every borehole matters, this reliability is essential.”
In addition to the improved access, an equal-wall stator enables high-pressure capability within a compact footprint. The pump can be equipped with a compact hydraulic drive for truck-mounted mobile units or an electric drive for underground or stationary installations. The low-displacement hydraulic option reduces oil requirements and contributes to a low total cost of ownership.
Applications
BN pumps with Smart Joint Access are suitable for rock blasting, shotcrete, mine dewatering, tunnelling, civil works, dam construction, and other industrial processes requiring precise and reliable handling of chemical or abrasive media. In blasting operations, a routine visual inspection of the joints, combined with operational pressure testing, is essential. Smart Joint Access allows operators to assess joint integrity quickly, supporting faster decision-making and continuous operation in uptime-critical environments.
