BNA Range

BNA Range

SEEPEX progressive cavity pumps from the BNA range are designed to fulfill the exacting requirements of the Oil & Gas Industry and meet American Petroleum Institute (API) standards.

BNA range pumps have rugged, heavy-duty castings in accordance with API 676 3rd Edition and casing parts made of super duplex stainless steel.

The maximum containment pressure for both suction and discharge is 50 bar. The flanges are according to ASME B16.5 – suitable for two times the external forces and moments required by API 676.

Additionally, SEEPEX offers fully API 682 compliant mechanical seals with optimized seal plans. ASTM materials, full traceability and compliance with NACE MR0175 are standard features. The pump can also be designed for gas hazardous areas.
