TECHNICAL OVERVIEW
What Is A
Boiler Pump?
A Boiler Circulation Pump is a high-pressure centrifugal pump installed within the boiler circuit of a steam power plant — maintaining forced circulation of water through the evaporator tubes and boiler drum.
SYSTEM REHABILITATION
BCP Overhauling
BCPs typically operate under extreme conditions: system pressures from 100 to 200+ bar, water temperatures approaching saturation point, and continuous duty cycles with minimal planned downtime.
Most modern BCPs use a canned motor or wet motor design where the rotor operates submerged in process fluid — eliminating mechanical shaft seals and associated leak risk at high pressures.

DEI VOX CAPABILITIES
BCP Specialist
Services.
A comprehensive suite of services around the Boiler Circulation Pump lifecycle — built on direct field experience across multiple plant types and pump configurations.
BCP Overhauling
Complete strip-down, component inspection, dimensional measurement, and restoration to original tolerances. Includes impeller reconditioning, bearing replacement, can liner inspection, and full-load performance testing.
In-Situ Casing Machining
Precision in-situ machining of pump casings without removing them from the boiler piping — minimising plant outage time and risk when BCP casings develop leaks at flange faces or body joints.
Motor Rewinding
Rewind of canned motor stators using high-temperature insulation rated for continuous immersion in hot process water. All rewinds are tested to IEC standards with IR, hi-pot, and surge comparison testing.
Spare Parts & Reverse Engineering
OEM spare parts for older BCP models are frequently discontinued. DEI VOX uses reverse engineering to recreate precise dimensional replicas of impellers, wear rings, bearing housings, and can liners.

MAINTENANCE FRAMEWORK
BCP Maintenance
Best Practices.
01
Continuous Condition Monitoring
Vibration, temperature, and differential pressure trending to detect bearing degradation or flow disturbances early.
02
Water Chemistry Control
Maintain oxygen levels, pH, and conductivity within boiler water quality standards to minimise corrosion of motor internals.
03
Planned Overhauls
At OEM-recommended intervals or based on condition trigger points — typically every 18,000–25,000 operating hours.
04
Wear Component Replacement
Wear rings, thrust bearings, can liner integrity checks at each planned outage to maintain OEM-spec clearances.
05
Emergency Response
24/7 on-site support when pump trips or abnormal performance is detected. DEI VOX mobilises within 24–48 hours anywhere in India.

FREQUENTLY ASKED
BCP
Questions.
Q1
What is a Boiler Circulation Pump (BCP)?
A BCP is a specialised centrifugal pump that circulates water through the boiler drum and evaporator tubes of a high-pressure steam boiler. It maintains controlled water flow rates to ensure uniform heat transfer, prevent tube overheating, and protect the boiler from thermal stress.
Q2
How often should a Boiler Circulation Pump be overhauled?
Typical overhaul intervals range from 12,000 to 24,000 operating hours depending on water chemistry, operating pressures, and manufacturer recommendations. DEI VOX recommends a condition-based maintenance approach with regular vibration monitoring and seal inspections.
Q3
Can DEI VOX repair BCPs from all major manufacturers?
Yes. We have extensive experience overhauling BCPs from all major OEM manufacturers including KSB, Sulzer, Weir, BHEL, and imported units. Our reverse engineering capability also enables us to produce hard-to-source spare parts for legacy pump models.
