Oberdorfer S2071FCB 316 Stainless Steel Chemsteel Gear Pump
This Oberdorfer S2071FCB is a precision-engineered Chemsteel gear pump designed for demanding industrial fluid handling applications. Constructed entirely from 316 stainless steel, this pump delivers exceptional corrosion resistance, making it ideal for aggressive chemicals, solvents, and high-purity fluids. Its positive displacement design ensures consistent, non-pulsating flow, even when handling high-viscosity liquids.
With a flow capacity of up to 4 GPM and operating speeds up to 1750 RPM, the S2071FCB provides reliable performance in metering, dosing, and transfer systems. The combination of stainless steel gears and PTFE components reduces noise and wear while extending service life. Its bi-directional operation adds flexibility for systems requiring reversible flow.
Engineered for durability and easy maintenance, this pump features a rugged three-section construction with O-ring sealing and a mechanical seal system designed for long-term reliability. It is widely used across chemical processing, pharmaceutical production, and industrial fluid transfer environments where contamination-free operation is critical.

FAQs
What makes the S2071FCB suitable for corrosive fluids?
Its full 316 stainless steel construction and chemical-resistant seals allow it to handle aggressive fluids like acids, solvents, and caustics safely.
Can this pump handle high-viscosity liquids?
Yes, it can handle viscosities up to 100,000 cP when operated at reduced speeds, making it suitable for thick fluids like resins and polymers.
Is the flow pulsation-free?
Yes, as a gear pump, it provides smooth, continuous, non-pulsating flow ideal for precision metering.
Does this pump require a relief valve?
Yes, like all positive displacement pumps, a pressure relief valve is recommended to prevent over-pressurization.
Can the pump run in reverse?
Yes, it supports bi-directional operation by reversing motor rotation.
