YZL Horizontal Forced-Circulation Axial-Flow Pump | RFQ Sourcing Details

The YZL is a horizontal, low-pressure forced-circulation axial-flow pump intended for industrial circulation duties. The listed configuration uses a single-stage, single-suction open impeller, an integral-cast combined casing, and variable-frequency drive control.

Published operating data gives a maximum capacity of 15,000 m³/h, a maximum head range of 1.5–7 m, and selectable rotational speeds of 320, 360, 380, 400, 500, 730, or 980 rpm. Supported construction and operating facts The impeller material is specified as customizable according to the application.

The pump is described with integral casting for the impeller, casing, and short pipe, plus a heavy-duty bearing assembly and wear-sleeve protection for the main shaft. The listed shaft deflection at the seal chamber is below 0.05 mm.

Temperature information includes a general operating range of -20°C to +180°C and bearing temperature ratings up to 120°C with grease lubrication or 180°C with oil lubrication.

The published product information reports a 5%–8% efficiency improvement over its referenced standard prototypes and a mechanical-seal service-life increase of two to three times compared with conventional designs.

These are comparative listing claims;buyers should request the test basis, reference pump, duty point, and acceptance criteria before using them in a project evaluation.

The listed applications include sodium aluminate evaporation, caustic soda and salt production, ammonium sulfate crystallization, flue-gas desulfurization, sodium-chloride evaporation crystallization, copper- and nickel-sulfate evaporation crystallization, alcohol concentration, citric-acid and sugar-solution evaporation, and black-liquor concentration.

Suitability for any specific fluid must still be confirmed against its concentration, solids content, crystal characteristics, corrosiveness, temperature, and required duty point.

Procurement questions to confirm Before ordering, provide the required flow, head, operating and design temperatures, fluid composition, solids or crystal content, density, viscosity, vapor pressure, and site elevation.

Confirm the selected impeller and casing materials, seal arrangement, lubrication method, inlet configuration, motor voltage and frequency, required speed-control method, and whether the supplied motor meets site efficiency or hazardous-area requirements.

Buyers should also obtain the model-specific performance curve, efficiency and NPSH data, dimensional drawing, flange details, motor rating, inspection plan, and applicable standard documentation.

The listing identifies ISO 5199, ISO 9906, and API 610, but the exact scope of conformity and supplied records should be verified for the ordered configuration. The stated package dimensions are 300 × 170 × 150 cm with a gross weight of 5,000 kg, packed in a plywood box.

Confirm whether these figures apply to the selected pump, motor, base, and accessories. Also confirm the final warranty terms, production schedule, spare-parts scope, commissioning support, preservation method, and shipping documentation in the purchase contract.
