Built to Solve Biopharma’s Toughest Pumping Challenges

Built to Solve Biopharma’s Toughest Pumping Challenges

Protect shear‑sensitive product

Standard multi‑lobe rotors reduce shear and pulsation—ideal for proteins, cells, and other sensitive media.

Confident cleaning & drainability

Self‑draining cover geometry and innovative internal cusps support fast, effective cleaning and product recovery. Optional zero dead‑leg drain maximizes yield.

Seal the sterile boundary

Choose single or double mechanical seals with flush or quench and biopharma‑ready elastomers—including USP Class VI options—to match your containment strategy.

Process versatility

Handles ultra‑thin buffers to high‑viscosity media; vertical or horizontal ports and Tri‑Clamp connections fit existing skids.

Compliance & documentation

3‑A Hygienic design and CE/UKCA/ATEX compliant models, plus optional performance & material certificates to accelerate validation.

Uptime by design

Front‑loading seals can be changed in‑line. Sealed‑for‑life bearings simplify gearbox care; maintenance kits help extend service life.

Performance at a Glance

Performance at a Glance

Improved Yield

High-efficiency rotary lobe design delivers consistent flow across pressure changes, with low shear for sensitive fluids. Flow is proportional to speed, enabling precise metering with a variable speed drive.

CIP & SIP Ready

Aseptic design supports clean-in-place and steam sterilization in place, reducing downtime and ensuring compliance with strict cleaning standards.

Scalable Performance

From 10 L/min benchtop systems to 2 m³/min (120,000 L/h) full-scale production, SteriLobe® grows with your process—simplifying scale-up and validation.

Easy Maintenance

Front-loading seals can be replaced without removing the pump, minimizing downtime and cost.
