Valve Failures, Clogging & Constant Recalibration

The Problem

Traditional diaphragm, syringe, and peristaltic pumps rely on check valves that wear, clog, and lose their seal over time. Crystallising fluids, particulates, and even plastic fragments from sample containers get trapped in valves, causing blockages, backflow, and accuracy drift. The result: unplanned downtime, failed test runs, and expensive field service calls just to replace parts that were always going to wear out.

How Fluid Metering Solves It

The CeramPump® has no valves at all. A single sapphire-hard ceramic piston performs both pumping and valving functions — nothing to clog, nothing to replace. It maintains 0.5% precision without recalibration, cycle after cycle, for millions of operations. There is no annual valve replacement schedule because there are no valves.

The Pump That Outlasts the Instrument

The Problem

Diaphragm pumps develop cracks near end of life, causing leaks and contamination. Peristaltic pump tubing degrades after hundreds to a few thousand hours and needs frequent replacement. Syringe pumps require glass barrel replacements, paired motor assemblies, and up to four electronic valve actuators per dispensing unit. Every replacement part means downtime, labour cost, and risk of introducing errors back into the system.

How Fluid Metering Solves It

Fluid Metering's CeramPump® is designed to last the lifetime of the instrument. The ceramic piston and mated liner are dimensionally stable and abrasion-resistant — they don't distort, stretch, or degrade. There are zero consumable parts. No diaphragms to crack, no tubing to swap, no glass barrels to replace. The pump you install on day one is the pump still running accurately years later.

Complex Fluidics Driving Up Cost and Machine Size

The Problem

To keep throughput high with syringe or diaphragm pumps, OEMs typically need separate pumps for priming, flushing, and dispensing. That means additional lines of tubing, selector valves, more potential leak points, and a larger instrument footprint. Each added component is another point of failure and another item on the maintenance schedule.

How Fluid Metering Solves It

Fluid Metering pumps are self-priming and valveless, which means a single pump can prime, flush, and dispense — replacing what previously required multiple pumps, selector valves, and metres of tubing. The FENYX® primes 10x–40x faster than a syringe pump. Fewer components means a smaller machine, fewer leak points, lower BOM cost, and dramatically simpler maintenance for end-users.

Aggressive Fluids Destroying Pump Internals

The Problem

Many medical, diagnostic, and industrial applications require pumping corrosive reagents, abrasive solutions, or fluids that crystallise when exposed to air. Conventional pump materials — rubber diaphragms, plastic manifolds, elastomer tubing — degrade under these conditions, leading to premature failure, contamination of samples, and compromised test accuracy.

How Fluid Metering Solves It

CeramPump® internals are made from chemically inert, sapphire-hard ceramics that resist corrosion and abrasion from even the most aggressive media. For crystallising fluids, an optional wash gland isolates the fluid from the atmosphere, preventing crystal buildup entirely. The pump handles whatever your application demands — without degrading, without contaminating, without failing.
