BNA RANGE
FOR LOW TO HIGH VISCOUS MEDIA WITH OR WITHOUT SOLIDS
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 725 PSI (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.
- Conveying capacity: 0.44 GPM–660 GPM (0.1–150 m³/h)
- Working pressure (MAWP): up to 700PSI (48 bar)
- Casing pressure (MACP): up to 725 PSI (50 bar)
BENEFITS
- All process parts are cast or machined – no welding required
- Reduced number of documents and fewer inspections
- API compliant
- Heavy duty design
- Standardized pump components
- Favorable lead time
