FMI Pump RHB Series Additive Pump, Direct Current, low flow version For Mobile, Remote & Instrumentation. Ideal for agricultural spraying, mosquito control, medical applications and hydrogen fuel cell research and development.

FMI Pumps feature the patented CeramPump® valveless piston pumping technology. The CeramPump® positive displacement design has one moving part in the fluid path, a sapphire-hard ceramic piston to perform all fluid control functions.

The elimination of valves minimizes downtime or the need for re-calibration and our long term drift-free performance delivers millions of “trouble-free” cycles at 1% precision or better.

Chemical Additive Pump Features

  • 2 V DC, 24 V DC, and 90 V DC motors with close-coupled RH/Q FMI Pump Heads
  • Chemical Additive Pump is widely used to inject discrete quantities of additive fluids into main discharge lines of tank trucks and pest control vehicles.
  • Ideal for environmental sampling & injection
  • Offers the advantage of mechanical adjustment of stroke length, plus electrical control of stroke rate by voltage variation
  • Extended motor shaft accepts FMI HES / PRS Rotational Sensor or user supplied rotational sensor.

*GENERAL SPECIFICATION NOTES FOR ALL PUMPS
  1. Physical characteristics of your pumped fluid may affect the rating/capacity relationships shown in the performance tables for each FMI pump.
  2. The maximum flow rates shown in the tables are for H2O at 2 psig.
  3. Flow rates are infinitely variable from zero to maximum capacities shown.
  4. Pumping capacities are reduced approximately 18% when the Pump Drive Module is operating on a 50 Hz electrical supply.
  5. Fluorocarbon cylinder cases (Q line only) are rated for a maximum pressure of 60 psig or the lower pressure shown in the charts.
  6. 3/8″ I.D. tubing or greater is required for flows higher than 500 mL/min.
  7. 1/2″ I.D. tubing or greater is required for flows higher than 1200 mL/min

RHB Chemical Additive Pump Series; Common Serial Numbers:

  1. RH00CTC, RH00SKY, RH00ZKC, RH00CTC, RHB1CKC, RHB1CTC
Accuracy of ± 1%. Can be expected for low to medium viscosity (1 – 500 cps) fluids providing, consistent precise output from microliters to full flow range.
The FMI pump is positive displacement and, in general, viscosity independent. However, viscous fluids should use lower RPM drives (400 RPM or less) with pump heads adjusted to longer piston strokes. There is no absolute value for the maximum viscosity an FMI pump can handle. For extremely viscous fluids, pressure feeding on the inlet side of the pump and/or heating of fluid are commonly used to aid in feeding fluid to the pump. FMI also manufactures temperature controlled pump heads “WT” to help maintain fluid temperatures up to 360 F as it flows through the pump.

On all pumps, flow rates may be altered when operating or at rest. On the “Q” line this is done by turning the Flow Control Knob which moves the flow rate indicator along a fixed 20 unit scale linearly calibrated “10-0-10”. The “10” equals 100% flow rate in that direction, “0” equals zero flow. To improve the fine adjustment of the flow rates on the “Q” line, there is an optional Dial Indicator Kit Q485 which provides for 1000 discrete settings. The “RH” line flow adjustment is accomplished by turning an easy-grip Flow Control Ring graduated in 450 divisions from 0 to 100% flow.

A variety of rotational sensors are available which will provide a signal for monitoring RPM. For pumps which utilize the standard Q style base, hall effect and proximity rotational sensors are available. For stepper motor driven pumps, opto-sensors can be provided.

Yes. Pumps will self prime to 15 feet vertical dry, 26 feet wet.

YES. FMI Sanitary Pump heads are designed for autoclaving, clean in place, or complete disassembly for brush cleaning. Cleaning procedures can be followed without loss of system operating efficiency.
