HXK Horizontal Rotary Casing Chemical Centrifugal | RFQ Sourcing Details

The HXK is a horizontal rotary casing centrifugal pump, also described as a pitot tube pump. Its rotating drum and rotor cover are designed so that the impeller and liquid rotate together.

The stated design intent is to reduce the disk-friction losses associated with some high-speed and multistage pump arrangements while providing stable hydraulic performance for small-flow, high-head duties.

The listed configuration uses a motor drive, single-suction impeller, combined horizontal split casing, and either mechanical-seal or packing shaft sealing. Transmission options include direct coupling, gearbox, V-belt, and universal joint arrangements.

Available listed materials include SS304, SS316, SS316L, titanium, Monel, 2205 duplex stainless steel, and CD4MC. The flange standard can be customized. Published selection limits include a maximum head above 150 m and maximum capacity of 2,050 m³/h.

These figures describe the listed product range and should not be interpreted as a guaranteed operating point for every material, drive, or configuration.

Buyers should request a model-specific performance curve and confirm the required flow, differential head, speed, power, efficiency, and allowable operating range before ordering. The identifies mechanical seals and O-rings as the principal wearing parts.

It also states that the seal is exposed only to inlet pressure and that the performance curve rises continuously from maximum flow toward shutoff.

Suitability for a specific chemical remains dependent on the selected metallurgy, elastomers, sealing arrangement, temperature, concentration, solids content, and operating conditions.

Listed application areas include coal chemical processing, petroleum and petrochemical operations, natural-gas and fine-chemical processing, chemical fiber production, desulfurization and denitration, thermal and biomass power generation, mining, nonferrous-metal smelting, iron and steel metallurgy, wastewater treatment, evaporation and concentration, MVR systems, ocean engineering, and lithium-battery production.

Before procurement, confirm the exact pumped-liquid composition, design and operating temperatures, suction conditions, required NPSH margin, pressure rating, motor and electrical requirements, hazardous-area needs, flange dimensions, seal materials, rotation direction, installation arrangement, inspection documentation, and included accessories.

Also verify the final package dimensions and gross weight because the supplied listing contains different general specification and delivery-package measurements.
