Where Rotary Jet Pumps Are Used

The standard range is 0.05–70 m³/h, with head up to 1,050 m. The liquid, speed and pick-up tube determine the selected operating point. Different processes can need the same head but different temperatures and inlet conditions.

Use the series limits for a shortlist and the selected performance curve for the actual requirement.

Boiler feedwater needs high head at a small flow, which this pump produces in one stage.

Send us: water temperature, feed flow, required head, inlet pressure, NPSHa and low-load demand.

Single-stage pressure generation and steady pressure at small flows suit carbon black quench-water supply.

Send us: water properties, particles and their size and hardness, normal and maximum flow, head, inlet conditions and any observed tube wear.

Reverse-osmosis feed needs high water pressure at the system flow, without several pressure-building stages.

Send us: water properties, temperature, flow, required delivery pressure, inlet pressure and changing demand.

A shared cleaning supply can keep steady pressure as outlets close, with a continuous bypass maintaining flow near the shut-off point.

Send us: flow with the intended outlets open, minimum demand, head, temperature, inlet supply and controls for the bypass.

Water injection and produced-water reinjection need high head within the selected pump flow range.

Send us: water properties, temperature, flow, inlet and outlet pressure, gas and solids. Increasing gas reduces flow and head; particle content affects tube and material selection.

Chemical and petrochemical transfer can require high pressure at modest flow, with wetted materials and seals selected for the liquid.

Send us: liquid name and composition, density, viscosity, temperature, flow, head, inlet pressure and seal-flushing requirements. Materials include carbon steel, ductile iron, 304 and 316 stainless steel, or duplex stainless steel; API seals and flushing systems are available.

Paper-machine showers benefit from steady water pressure as demand varies within the selected operating range.

Send us: water flow, head, temperature, inlet supply, solids and demand range. State whether one shower or a shared supply is served, so the low-flow bypass can be reviewed.

Choose a bare-shaft pump, motor-pump set or complete skid. For replacement work, identify any piping and drive to retain. Photos are optional.

The proposal includes the selected speed and tube, a performance curve and project drawings. State where inlet and outlet pressures are measured if head has not been calculated.
