Overview

Product Overview

Product Description

HSA Series API BB2 Pump – Built for Severe Process Duty

Radially split, single-stage double-suction design minimizes NPSH and balances axial thrust. Heavy-duty bearing housing with forced oil lubrication. Dual mechanical seals with API flush plans. Centerline mounting absorbs thermal expansion. Wide material selection for sour service, high chloride, or high-temperature hydrogen environments.

KEY FEATURES

  • API 610 BB2 Compliance: Fully compliant with 11th edition API 610 (BB2 type) – radial split, single‑stage, double‑suction design for high reliability in hydrocarbon service.
  • Ultra-High Pressure Capability: Maximum working pressure up to 15MPa (150 bar / 2175 psi), suitable for hydrogenation and high‑pressure pipeline applications.
  • Extreme Temperature Range: Engineered for -80°C cryogenic to +450°C high‑temperature operation, covering LNG, hot oil, and steam systems.
  • Double‑Suction Impeller: Hydraulically balanced design significantly reduces axial thrust, extending bearing and wear ring life.
  • Advanced Sealing & Materials: Single or dual mechanical seals with API flush plans; materials from carbon steel to duplex, high‑temp alloy, and lined options for corrosive/erosion service.

Frequently Asked Questions

What does API 610 BB2 mean, and why is it important for my refinery?
API 610 is the global standard for centrifugal pumps in petroleum, petrochemical, and gas service. BB2 denotes a radially split, single‑stage, double‑suction horizontal pump. This design offers high efficiency, low NPSH, and easy maintenance without disturbing piping. Using an API BB2 pump ensures reliability, safety, and compliance with refinery best practices.
Can the HSA pump handle high‑temperature hydrogenation feed service up to 15MPa?
Yes. The HSA series is specifically designed for high‑pressure, high‑temperature hydrogenation feed applications. With a maximum working pressure of 15MPa (150 bar) and temperature capability up to 450°C, it is fully suitable for hydrocracker and hydrotreater feed services when configured with appropriate high‑temp alloy metallurgy and dual mechanical seals.
What material options are available for sour water or high‑chloride media?
For sour water (wet H₂S), we recommend duplex stainless steel (e.g., 2205) or super duplex to resist sulfide stress cracking. For high‑chloride environments (e.g., seawater or certain petrochemical streams), 316L or higher grade super austenitic stainless steel is available. Please provide your fluid composition and operating conditions for precise material selection.
How is the axial thrust balanced in this single‑stage double‑suction pump?
The HSA pump uses a double‑suction impeller, which has two back‑to‑back vanes that draw liquid from both sides. This design inherently balances hydraulic axial thrust, eliminating the need for complex thrust bearings. Only residual imbalance remains, easily handled by standard angular contact bearings – resulting in longer life and lower maintenance.
What API flush plans are supported for the mechanical seals?
The HSA series supports common API flush plans including Plan 11 (internal recirculation), Plan 21 (cooled recirculation), Plan 23 (thermosiphon with cooler), Plan 31 (cyclone separator), and Plan 53/54 for dual seals. Our engineers will recommend the optimal flush plan based on your liquid properties, temperature, and pressure.
