What is the Ishii Machinery Works PBCSH Boiler Water Circulation Pump?

The Ishii Machinery Works PBCSH Boiler Water Circulation Pump is a horizontal single-suction centrifugal pump specifically intended for boiler water circulation and associated services in marine and industrial systems.

Key Technical Specifications

Specification

Details

Nominal Diameter

φ50 mm, φ100 mm

Capacity (Flow Range)

8 – 40 m³/h

Total Head

20 – 60 m

These performance ranges make the Ishii Machinery Works PBCSH Boiler Water Circulation Pump well suited for mid-head, moderate flow applications where stability and reliability are non-negotiable.

Design Features & Advantages

  • Horizontal, single-suction layout – allows compact base mounting and simplified installation and maintenance.

  • Engineered for continuous service – ideal for boiler circulation and process water use; built with durable materials (to be confirmed per fluid and project standards).

  • Model designations such as “50-PBCSH-3” or “50-PBCSH-5D” help ensure spare parts compatibility, traceability, and correct configuration.

These features combine to give users easy maintenance, reliable operation, and manageability in tight mechanical spaces.

Typical Applications

  • Boiler water circulation (primary application)

  • Auxiliary water services (fresh or sea water), especially where medium head and flow between 8-40 m³/h are needed

  • Marine settings, industrial plants, and systems requiring pumping of water under boiler-rated or process conditions
