CeramPump Valveless Technology for Precise Metering

Traditional metering pumps rely on check valves that are prone to clogging, sticking, or failing over millions of cycles. Based on FMI’s proprietary CeramPump® valveless piston principle, this system offers accurate positive displacement metering with only one moving component in the fluid path.

This elegant design minimizes mechanical drift and drastically reduces maintenance requirements. Because the pump is reversible, it supports bidirectional metering without the need for check valves or complex bypass lines, maintaining stable performance even during continuous high-cycle dosing.

RH1CTC Ceramic Pump Head Performance

The RH1CTC head belongs to the elite RH pump head family, which utilizes a completely nonmetallic ceramic (or zirconia) piston and matching ceramic cylinder liner. This provides exceptional wear resistance and tight volumetric control, delivering a highly stable performance with a Coefficient of Variation (CV) of ≤0.5% for repetitive dispensing.

With the QV drive’s variable speed and a fully adjustable stroke length (from 0 to 100%), operators can seamlessly tune flow from microliters per minute up to robust transfer rates. When operating at full stroke and rated maximum speed, this 1/4-inch piston configuration delivers a maximum flow rate of up to approximately 576 mL/min.

Extreme Chemical Compatibility & OEM Integration

Equipped with chemically resistant casing materials such as PVDF, ETFE, or polypropylene, the RH1CTC head provides broad compatibility with aggressive industrial chemicals and high-purity fluids. Furthermore, the compact 1/4-inch shaft design makes mechanical integration straightforward, ensuring this pump is ready to be dropped into OEM analyzers, automated chromatography systems, and pilot plant skids.

Frequently Asked Questions (FAQ)

What is the maximum flow rate of the FMI QV pump with the RH1CTC head? When operating at full stroke and rated maximum speed, this specific configuration (utilizing the 1/4-inch piston RH head) can achieve a maximum flow rate of up to approximately 576 mL/min.

What fluids can the RH1CTC pump head handle? The RH1CTC pump head is designed for broad chemical compatibility. It features a completely nonmetallic fluid path consisting of a ceramic piston and cylinder liner, housed in a highly resistant PVDF, ETFE, or polypropylene casing. This makes it ideal for safely handling aggressive industrial solvents, harsh acids, and high-purity laboratory fluids.

How accurate is the FMI CeramPump design? The CeramPump design is exceptionally accurate for both continuous metering and batch dosing. Because it uses a valveless positive displacement mechanism with a precision ceramic piston, it eliminates the inconsistencies caused by sticking check valves, achieving a remarkable Coefficient of Variation (CV) of ≤0.5% for repetitive dispensing.
