The company describes centrifugal, investment and static casting, together with CNC turning, grinding, milling and boring. Its published inspection capabilities include direct-reading spectroscopy, metallography, hardness and mechanical testing, non-destructive examination and chemical analysis. These are company-reported manufacturing resources.
The ECP evaporator-circulation family below serves a different hydraulic requirement from a low-head axial-flow pump. Longsheng describes its use where an evaporation loop needs additional head, including higher-resistance or multi-pass arrangements. Its documentation links the pumping principle to loop layout, liquid properties and material selection.
The catalog now distinguishes ECP evaporator mixed-flow service, SPP mixed-flow transfer and HZW-II axial forced circulation. SPP motor selection is shown for different liquid densities; HZW-II lists shaft power separately from a motor rating. Circulation-loop losses, liquid density and available suction conditions should be established before choosing the drive.

Technical enquiry
- Provide circulation flow, loop losses, liquid density and temperature, available NPSH and corrosion or solids conditions. Confirm impeller trim, motor allowance, seal and piping loads.
- Provide required circulation duty, liquid density, temperature, crystal or abrasive loading and loop geometry. Confirm wetted materials, seal arrangement, belt ratio, motor sizing and pipe supports.
