VS Series Boiler Feed Pump Model Selection & Specifications

Specialized Boiler Feed Water Solutions

Our vertical multi-stage pumps are the industry standard for boiler feedwater applications. When dealing with high-temperature fluids and requiring continuous, high-pressure water supply, reliability is non-negotiable. Boiler Feedwater Pump Guide

  • Energy Efficiency: Integrated VFD and PLC intelligent control systems reduce energy consumption by up to 40%.
  • Advanced Metallurgy: Choose from durable Cast Iron, SS304, or SS316 to suit high-temperature deaerated and softened water requirements.
  • Low NPSH Performance: Optimized hydraulic designs minimize vibration and prevent cavitation in high-temperature loops.

High-Pressure Vertical Multistage Series

Structure of boiler feedwater pump

FILIPUSI Vertical Boiler Feed Pump Structural Integrity:  Engineered for industrial steam boiler systems, our vertical multistage feedwater pump features a heavy-duty pump body, precision-balanced laser-welded impellers, high-temperature resistant shafts, and specialized mechanical seals. The optimized hydraulic design with axial thrust balance systems significantly lowers the failure rate under continuous high-pressure conditions.

  • Main components: The boiler feedwater pump consists of key components such as the pump body, impeller, shaft, bearings, and sealing device.
  • Working principle:The motor drives the impeller to rotate at high speed, generating centrifugal force, which sucks in and pressurizes water before transporting it to the boiler.
  • Performance characteristics: The pump has high temperature and high pressure resistance, which can ensure the stable water supply demand of the boiler system.
  • Advantages of self balancing multi-stage pump:FILIPUSI adopts advanced structural design, effectively reducing failure rate, and is suitable for boiler feedwater systems.

Boiler Feed Pumps Procurement - FAQ

Q1: What materials do you offer for high-pressure boiler feed pumps?
A1: FILIPUSI provides standard cast iron, cast steel, SS304, SS316, and Duplex Stainless Steel (SS2205) configurations. For heavy-duty supercritical or highly corrosive feedwater applications, we highly recommend custom SS316L or duplex steel to maximize pump wear life.

Q2: Can your boiler water supply pumps be customized with automated control systems?
A2: Yes, absolutely. All FILIPUSI vertical and horizontal boiler pumps can be fully integrated with custom-engineered VFD (Variable Frequency Drive) and PLC intelligent control panels, enabling automated millisecond-level steam-water balance tracking.

Q3: What is the typical lead time and manufacturing standard for B2B bulk or custom orders?
A3: Standard specifications generally ship within 7–15 business days. Custom engineering configurations requiring specific material casting or complex auxiliary valves take approximately 25–40 days. All pump manufacturing strictly aligns with international safety and industrial testing protocols.
