Introduction

Our cGMP-grade XAccurflow^{^®} High-Precision Diaphragm Pump is designed and manufactured in-house, with 316L and medical-grade polymer wetted parts delivering outstanding biocompatibility. Low-shear transfer technology minimizes physical damage to the conveyed medium, while a unique zero-dead-leg quick-disconnect design with the fluid path physically isolated from moving components eliminates residue contamination and leakage risks. Full CIP/SIP support throughout makes it ready for the most demanding biopharmaceutical applications.

Features

High-precision stable output, mass-flow-meter accuracy (±0.5–1%), built-in flow calibration against temperature, pressure and viscosity, smooth ultra-low-flow transfer
Four-diaphragm alternating action, stable low-shear low-pulsation flow at up to 6 bar, preserving biomolecule activity and integrity
Nine models, 0.9–10,000 LPH flow range, linear scale-up from bench to full-scale production
Switchable single-use and stainless-steel pump heads; single-use heads prevent cross-contamination for sensitive fluids and multi-product campaigns, stainless-steel heads for CIP/SIP service
Two pump formats: high-integration system pump for skid-mounted process systems, compact standalone pump for independent transfer units
Modbus_RTU (RS485) and 4–20 mA analog I/O across the range, seamless PLC and supervisory-system integration, dedicated maintenance kit for in-place service

Application Scenarios

Ultrafiltration systems: stable, low-pulsation feed transfer that keeps membrane separation efficiency on target.
Chromatography systems: high-precision flow control for reproducible, high-resolution separations.
Buffer preparation systems: accurate delivery of buffers and media, with full CIP/SIP support.
Filtration systems: low-shear transfer protects biomolecules for clarification and sterile filtration.
Fermentation systems: harvest broth transfer.
Reactor systems: precise charge feeding for consistent reaction performance.
Homogenization systems: stable transfer of high-viscosity fluids to suit high-pressure homogenization.
