BNA - RANGE BNA, API 676

Product catalog summary

Overview: The SEEPEX progressive cavity pumps from the BNA range are specifically designed to meet the stringent requirements of the Oil & Gas Industry, adhering to the American Petroleum Institute (API) standards, particularly API 676.

Specifications: The pumps feature rugged, heavy-duty castings made of super duplex stainless steel, compliant with API 676 3rd Edition. They can handle a maximum containment pressure of 50 bar for both suction and discharge, with flanges conforming to ASME B16.5 standards.

Compliance and Features: The pumps are equipped with fully API 682 compliant mechanical seals and optimized seal plans. They use ASTM materials, offer full traceability, and comply with NACE MR0175. Optional features include NORSOK qualified casing items, motors according to IEEE841/NEMA, and dry-running protection devices.

Key Facts: The pumps have a conveying capacity of 0.1–150 m3/h (0.44–660 USGPM) and a working pressure (MAWP) of up to 48 bar (700 psi). The casing pressure (MACP) can reach up to 50 bar (725 psi).

Benefits: The design eliminates the need for welding, reduces documentation and inspection requirements, and ensures API compliance. The pumps are heavy-duty, with standardized components and favorable lead times.

Components: The stator is available in various elastomer materials for different pressure levels. The mechanical seal is fully API 682 compliant. The lantern is made of cast stainless steel, and the drive includes a reduction gearbox with NEMA or IEC electrical motors. The baseplate can be customized according to API 676 or customer requirements. The pressure branch and suction casing are designed to handle high pressures and are available with Class 300 or Class 150 flanges.
