IB Series Close-Coupled End-Suction Centrifugal Pumps

Barmesa IB Series Close-Coupled End-Suction Centrifugal Pumps

The Barmesa IB Series is a line of close-coupled end-suction centrifugal pumps engineered for water transfer, booster systems, chilled water circulation, industrial fluid handling, and high-flow medium-pressure applications. Available in configurations from 1 HP to 15 HP and operating at either 1750 RPM or 3500 RPM, the IB Series provides efficient performance for commercial, industrial, irrigation, and process water systems.

Designed around centrifugal pumping principles, the IB Series converts impeller rotation into fluid velocity and pressure, making these pumps ideal for applications requiring consistent flow rates, dependable pressure generation, and efficient liquid movement. Available suction sizes range from 2" to 3" NPT, with discharge sizes from 1½" to 2½" NPT, supporting a variety of system requirements.

Engineered for Reliability

The IB Series utilizes heavy-duty materials throughout its construction to provide long service life and dependable operation.

Key construction features include:

• Cast iron volute

• Cast iron intermediate coupling

• Dynamically balanced 304 stainless steel impeller

• Stainless steel shaft sleeve

• Buna-N O-rings

• Mechanical shaft seal

• Carbon steel hardware

• Air-dry enamel protective finish

The 304 stainless steel investment-cast impeller is dynamically balanced to promote efficient hydraulic performance and smooth operation across the pump's operating range.
