Fluid Metering's RHV system injects hydrazine

Fluid Metering product story

Fluid Metering's RHV variable-speed valveless piston pumps with ceramic internals are ideal for directly injecting hydrazine into water and steam systems used in power-plant applications.
In most power plants, hydrazine is typically used as an anti-corrosion agent and is pre-mixed and diluted before injection.
This requires special holding tanks, large pumps and constant maintenance.
FMI's RHV system removes the need for these by injecting concentrated hydrazine directly into the water lines at system pressure, without dilution.
The RHV will inject hydrazine at rates as low as 0.2 millilitres per minute up to 180 millilitres per minute at an accuracy of one per cent or better.
FMI's RHV is self-priming and will not lose prime even at very low flow rates.
The integral miniature pump-head features chemically inert, sapphire-hard ceramic internals, which provide millions of maintenance-free, calibration-free cycles of service.
The RHV is controlled using FMI's V300 Variable Speed Controller, which includes a 4-20mA electronic-control input, typically used in process-control applications.
The RHV has a small footprint and is energy efficient.
It operates at less than 50W.
It provides an excellent return on investment, often paying for itself within a few months.
The V300 accepts a universal power input of 100-240VAC 50/60Hz.
