Chemical plants use high-pressure, low-flow pumps to feed pressurized reactors, supply spray nozzles and deliver cleaning water at high pressure. The fluid may be corrosive, and its properties can change from batch to batch.
Pitot tube pumps are compared for these services when the required head is high for the flow and steady, non-pulsating delivery is needed.
Liquids charged into reactors or vessels operating under pressure need a pump that can hold discharge pressure over the feed range.
Pressure nozzles in spray dryers, scrubbers and coating lines need stable pressure to keep droplet size consistent.
Cleaning of vessels, exchangers and lines can require water at high pressure and modest flow.
Composition, concentration and contaminants decide the wetted materials for the rotor, pitot tube and casing.
Viscosity and density can change with concentration, temperature and batch recipe, which shifts the operating point.
Hazardous or toxic fluids require a suitable seal arrangement and plant-approved containment.
For suitable chemical duties, a pitot tube pump gives high head in a single stage and steady flow to nozzles or pressurized vessels. Material compatibility and seal selection are confirmed against the safety data sheet and plant standards before a pump is proposed.
Learn how pitot tube pumps work, or review the high pressure low flow pump selection data. If the installed unit is a Roto-Jet® pump, see the Roto-Jet pump replacement process and replacement parts supply.
Start with the minimum, normal and maximum flow, suction and discharge pressure, fluid, temperature and viscosity, plus the current pump model and curve if a unit is being replaced. For chemical service, attach the safety data sheet, composition and concentration range, temperature, viscosity across the batch range and any containment requirements.
