Petrochemical plants have many small but demanding services: injecting water or solvent into high-pressure streams, feeding pressurized reactors and columns, and supplying water to steam generation packages.
Where the head is high for the flow, a pitot tube pump can be compared with multistage and positive displacement pumps.
Quench, wash or solvent streams injected into high-pressure process lines need a pump that overcomes line pressure at modest flow.
Hydrocarbon or solvent feed into pressurized equipment requires stable discharge pressure across the feed range.
Small boilers and steam generators need feed water at boiler pressure with flow following steam demand.
High vapor pressure fluids leave little suction margin, so NPSH available must be reviewed with temperature and piping losses.
Seal arrangement, emissions limits and hazardous-area motor requirements follow the plant classification.
Owner specifications may reference industry standards for pumps, seals and testing; state which apply with the inquiry.
A pitot tube pump reaches high head in a single stage and delivers non-pulsating flow, which suits injection and feed duties at modest flow. Suction conditions, fluid vapor pressure, seal requirements and plant specifications are reviewed before a configuration 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 petrochemical service, include fluid composition and vapor pressure, hazardous-area classification, seal and emissions requirements and the applicable plant specifications.
Send Operating ConditionsInjection, feed and small boiler feed duties that need high pressure at modest flow are typical candidates, subject to suction conditions and fluid properties.
Vapor pressure, temperature, suction pressure and piping losses are used to confirm suction margin before the pump is selected.
