Boiler Feedwater Pump for Hydrogen Steam Plant – High‑Efficiency, Corrosion‑Resistant Solution
The boiler feedwater pump for hydrogen steam plant is engineered to deliver precise, continuous flow of ultra‑pure water into high‑temperature hydrogen generators. Designed for continuous‑duty operation, this pump maintains strict water chemistry, minimizes hydrogen embrittlement risk, and supports the demanding thermodynamic cycles of modern steam‑hydrogen facilities.
Application Scenarios
Our pump is the backbone of several critical processes:
- Primary feedwater circulation in on‑site hydrogen reformers where steam‑driven electrolysis occurs.
- Secondary loop circulation for waste‑heat recovery units that feed steam back into the hydrogen synthesis loop.
- Closed‑loop cooling for high‑pressure boiler sections in integrated gasification combined‑cycle (IGCC) plants that produce hydrogen as a by‑product.
- Water‑hammer mitigation in large‑scale hydrogen production facilities requiring rapid pressure adjustments.
Each application demands a pump that can handle temperatures up to 350 °C, pressures of 25 bar, and a duty cycle of 24 × 7 months‑on‑end. Our design meets those thresholds while delivering energy‑efficient performance.

Key Benefits & Features
- Energy‑saving hydraulic design: Optimised impeller geometry reduces motor load by up to 12 % compared with conventional units.
- Hydrogen‑compatible sealing: Double‑lip mechanical seals with PTFE‑lined faces eliminate leakage of hydrogen‑laden water.
- Robust corrosion protection: Use of SS316L or duplex 2205 guarantees >10 years service in high‑temperature, low‑pH environments.
- Integrated condition monitoring: Optional vibration and temperature sensors feed real‑time data to plant SCADA systems.
- Modular construction: Quick‑change impeller and motor assemblies minimize downtime during routine maintenance.
- Compliance and safety: Engineered to meet ASME, IEC 61508 (functional safety), and ISO 9001 quality standards.
Industry Certifications & Safety
Our pumps carry the following certifications, ensuring they can be installed in regulated hydrogen production sites worldwide:
- ASME Boiler and Pressure Vessel Code (BPVC) – Section I & VIII.
- IEC 61508 SIL‑2 (where a safety‑instrumented system is required).
- ISO 9001:2015 Quality Management System.
- EN 13445 (European pressure equipment directive).
- ATEX/IECEx certification for equipment operating in explosive atmospheres (optional on request).
All materials and welding procedures are traceable, and each pump undergoes hydrostatic testing at 1.5 × design pressure before shipment.
Frequently Asked Questions
What is the minimum order quantity (MOQ) for a custom‑size pump?
We typically require an MOQ of 2 units for fully custom designs, allowing us to program dedicated tooling and validate performance. Standard‑size models are available with a single‑unit MOQ.
Can the pump be integrated with existing VFDs?
Yes. All units are supplied with a 400 V, 3‑phase motor that accepts standard VFD signals (0‑10 V, 4‑20 mA, or Modbus). A factory‑installed VFD kit can be added at no extra engineering cost.
What is the typical lead time?
Standard models ship within 15‑25 days after order confirmation. Fully customized configurations require 30‑45 days, depending on material selection and testing scope.
Is there a warranty and what does it cover?
All pumps come with a 24‑month or 2000‑hour warranty covering defects in material and workmanship. Extended warranties and on‑site service contracts are available on request.
