Vacuum Regulators

Equilibar precision vacuum regulators are designed specifically to control a highly stable inlet pressure across widely varying input conditions. These regulators show very little effect from either variation in supply vacuum or changes in flow rate. Equilibar precision vacuum regulators work differently than traditional vacuum control valve designs. The Equilibar uses a flexible diaphragm as the only moving part. This diaphragm is used to directly seal against the internal valve orifices. This eliminates the “stiction” commonly found in traditional vacuum control valves that rely on dynamic o-ring or wiper type seals. The friction caused by these seals prevents the regulator from making tiny adjustments. The Equilibar design is frictionless and can control vacuum with very high resolution.

Humidifiers, Evaporators & Filling/Dosing Systems

In these busy times, our customers sometimes ask us to build the products we supply into finished or semi-finished assemblies thereby allowing their engineers to focus on the more important aspects of the project. These “systems” can therefore be complete packages for gas and liquid supply, mixing, dosing, filling, evaporation and vapour source generation or, just as easily, they can be gas-sticks, manifolds or simple panels. Whilst existing designs can be supplied it is far more common that a specific configuration is required and PCT can help throughout the whole design process.

Valveless Piston Pump

Advantages of a valveless piston pump:

- There are no valves to service, leak, hang up, or clog.

- Features only one moving part.

- Equipped with ceramic internals.

- Ensures drift-free operation.

- Offers precision dispensing with a variation coefficient of -0.5%.

- Flow rates range from microliters to 2.3 liters/min.

- Provides positive displacement up to 6.9 barg.

- Capable of self-priming up to 4.5 meters.

- Features instant reversibility.

- The fluid path is inert, made of ceramic and fluorocarbon.

- Performance is viscosity independent.

- Comes with a wide selection of drives.

Fluid Metering Inc. has been a leading manufacturer of metering pumps and dispensers for over 60 years in the USA, having introduced the first valveless rotating and reciprocating piston metering pump. Over time, FMI's metering pumps have been refined and remain a benchmark for accuracy, precision, and durability in the industry.
