Stainless Steel High Pressure Constant Flow Pump For Formic Acid

CX-HL-0010MINI Stainless Steel High Pressure Constant Flow Pump – Reliable Formic Acid Delivery

Introduction

When your application demands precise, pulse-free, and high-pressure delivery of corrosive solvents like formic acid, choosing the right pump is critical. The CX-HL-0010MINI is a compact stainless steel high pressure constant flow pump specifically designed to handle such challenging tasks.

Whether you are working with HPLC systems, chemical dosing, or laboratory automation, this pump delivers laboratory-grade accuracy in a small footprint.

Key Specifications at a Glance

Why Choose the CX-HL-0010MINI for Formic Acid Delivery?

1. 316L Stainless Steel Construction – Corrosion Resistant

Formic acid is a corrosive organic acid that can damage ordinary pumps. The CX-HL-0010MINI is built with 316L stainless steel, offering excellent resistance to formic acid and many other aggressive chemicals. This ensures long-term reliability and prevents contamination of your process fluid.

2. Double Plunger Series Design – Smooth & Continuous Flow

Unlike single-plunger pumps that produce significant pulsation, the double plunger series configuration delivers a much smoother flow. With pressure pulsation as low as 0.5% at 10 MPa / 1 mL/min, your downstream instruments (e.g., columns, detectors, or reactors) experience less disturbance and better performance.

3. Ultra-High Precision – ±0.15% Flow Accuracy

For critical applications like formic acid dosing in analytical chemistry or pharmaceutical synthesis, consistency is everything. The CX-HL-0010MINI offers:

• Flow accuracy of ±0.15%

• Repeatability (RSD) of 0.1%

This means you can trust the pump to deliver the same volume cycle after cycle, day after day.

4. High Pressure Capability – Up to 42 MPa

Working pressures up to 42 MPa (6,090 psi) allow the CX-HL-0010MINI to be used in high-pressure liquid chromatography (HPLC), high-pressure chemical injection, and other demanding applications where low-pressure pumps would fail.

5. Flexible Control – RS232 or LAN

Integration into automated systems is straightforward with RS232 and LAN (Ethernet) communication options. You can remotely set flow rates, start/stop the pump, and monitor performance from your central control system or PC.

6. Compact & Power Efficient – 75W

The MINI in CX-HL-0010MINI means just that – it is small in size yet big in performance. With only 75W power consumption, it can be easily integrated into benchtop systems, portable analytical instruments, or OEM equipment without excessive heat or power draw.

Typical Applications

The CX-HL-0010MINI is ideal for:

• HPLC & LC-MS systems – precise mobile phase delivery, especially for formic acid-containing buffers

• Chemical dosing – metering corrosive acids like formic acid into reactors or mixing vessels

• Laboratory automation – constant flow delivery for long-duration experiments

• Pilot plant processes – reliable high-pressure feeding of reactive chemicals

• Ion chromatography – stable baseline performance due to low pulsation

Practical Tip: Operating at 0.1–0.5 mL/min

While the pump can deliver up to 9.999 mL/min, the recommended operating range for best precision and longevity is 0.1–0.5 mL/min. At these flow rates, you achieve:

• Maximum pressure stability

• Lowest pulsation

• Minimal seal wear

• Excellent repeatability (0.1% RSD)

For formic acid delivery in analytical or fine chemical applications, this range is often exactly what you need.

Installation & Port Sizes

• Inlet: 1/8" fitting – connect to your solvent reservoir or mobile phase bottle

• Outlet: 1/16" fitting – connect to your HPLC column, reactor, or other downstream equipment

Standard HPLC fittings and tubing are compatible, making integration into existing systems hassle-free.
