Cole-Parmer Bronze Close-Coupled Gear Pump System; Relief/2.1 GPM/ODP -- GO-70738-42




• Rugged corrosion-resistant bronze construction provides long service life
• Compact footprint with close-coupled design
• Easy assembly to NEMA and IEC motor frames
These rotary gear pumps are suitable for all liquids that are compatible with bronze—most common liquids are water, oil, and mild chemicals (pH from 4 to 11). Long service life is achieved through thoughtful design and chosen materials of construction: bronze pump housings and gears, 303|stainless steel shafts, carbon-graphite bearings, and Buna N lip seal.
Choose a gear pump head to mount to your own motor (adapters for NEMA or IEC motors are sold separately below) or select a complete system with the pump head conveniently mounted to a standard (NEMA 56C) TEFC motor.
