FJX Horizontal Axial Flow Circulating Pump for Ev | RFQ Sourcing Details

Product overview The FJX series is a horizontal axial flow circulating pump designed for large-flow, low-head service in evaporation, concentration, and crystallization systems.

Listed process areas include caustic soda, phosphate fertilizer, alumina, calcium chloride, sugar, salt, papermaking, and wastewater operations. The published range includes models FJX250 through FJX1000.

Depending on the selected model, listed flow capacity ranges from 300 to 13,000 m³/h, head ranges from 2.4 to 6.8 m, operating speed ranges from 200 to 1,450 r/min, and allocated power ranges from 18.5 to 315 kW. These values are model-specific and should not be treated as interchangeable across the series.

Design and maintenance features The pump is described as a slow-speed, cantilever-rotor design with a horizontally positioned shaft and direct-connected transmission. Its center-supported pump body is intended to keep the rotor thermally neutral.

A rear-door construction permits rotor extraction without disconnecting the pump-body inlet and outlet flanges, supporting more convenient maintenance. The design is also described as suitable for low-liquid-level evaporators and for evaporators with high-resistance heating chambers on the pump inlet side.

Flow and head can be adjusted through blade installation angle and speed changes.

Published shaft-seal options include a cartridge mechanical seal with a stated service life of 6–12 months and a liquid-blocking packing arrangement with a stated packing life of 3–6 months;actual seal life will depend on the selected configuration and operating conditions.

Available construction materials are listed as including Ni-Hard alloy, 1. Cr18. Ni9. Ti, 304L, CW-2, 316L, 904L, CD4MCu, MM-4, 2507, duplex-steel grades, J-1, JM3, JM6, Kazak B, C alloy, Monel alloy, titanium, and nickel alloy.

Material availability does not establish chemical compatibility, so the wetted-material selection must be confirmed against the buyer’s complete fluid data.

Procurement questions to confirm Before ordering, confirm the required duty point, liquid composition, concentration, temperature, density, viscosity, solids or crystal content, inlet conditions, and available NPSH.

Ask for the proposed pump curve, efficiency data, motor rating, blade setting, rotational speed, shaft-seal plan, wetted materials, and corrosion or erosion allowance for the actual service.

Also confirm the exact port sizes and flange standard, motor voltage and frequency, enclosure and hazardous-area requirements, installation orientation, cooling-water requirements, controls, instrumentation, accessories, inspection documents, certification scope, package dimensions, gross weight, manufacturing schedule, and warranty start conditions.

The listing contains both general package data and model-specific performance data, so a configuration-specific datasheet and drawing should be approved before production.
