ECP201L PREPARATIVE PUMP

Significance of the topic

The ability to deliver large solvent volumes at high pressure is critical for preparative liquid chromatography in pharmaceutical, biotechnology, and industrial purification workflows. Robust and precise pumping systems enhance throughput, reproducibility, and overall process efficiency when isolating target compounds on a preparative scale.

Objectives and overview

This summary examines the ECP201L preparative pump by ECOMAC, detailing its key design features, operating range, control options, and suitability for high-throughput separations. It highlights how the pump addresses common demands in preparative chromatography.

Methodology and instrumentation

The ECP201L employs two parallel pistons (20 mm diameter) to achieve pressures up to 15 MPa at flow rates from 1 to 1000 mL/min. Its control architecture integrates with ECOMAC and Clarity software via RS232, LAN, USB, and I/O interfaces. A high-pressure gradient mode allows coordination of up to four pump units from a PC. For buffered solvents, piston back-washing maintains seal integrity.

Main results and discussion

Performance specifications include:

• Flow rate range: 1–1000 mL/min in 1 mL/min steps
• Repeatability: ±1 %
• Accuracy: ±2 %
• Maximum pressure: 15 MPa at maximum flow
• Wetted materials: stainless steel, PEEK, Tefzel™, Kalrez®, ceramic, ruby
• Power requirements: 100–240 V AC, 500 VA
• Footprint: 276 × 153 × 620 mm, weight 26 kg

This blend of high flow capacity, precision, and chemical compatibility supports demanding preparative protocols while ensuring long-term reliability.

Benefits and practical applications

The ECP201L pump offers:

• Scalable throughput for industrial-scale purifications
