The OB109MB-01J26 is a bronze close-coupled centrifugal pump and motor assembly designed for quiet, efficient fluid transfer in marine, HVAC, and light industrial applications. Featuring a 1 1/4" NPT inlet and 1" NPT outlet, this unit includes a 1/2 HP open drip-proof (ODP) motor and a Buna (NBR) mechanical seal for reliable performance.

This model is a standard in the marine air conditioning industry, offering smooth operation and flexible discharge port orientation. It includes a carbon/ceramic mechanical seal with Buna elastomer, and a Monel shaft for enhanced corrosion resistance in demanding environments.

Recommended Applications:
