Jiangsu Fengchao Pump Industry Co., Ltd. QDL / QDLF
Fengchao QDL and QDLF are vertical multistage centrifugal pumps for thin, clean liquids without solid particles or fibres. The catalog distinguishes non-corrosive QDL service from mildly corrosive duties using QDLF configurations.

Product details
The vertically stacked hydraulic stages provide pressure development within a compact footprint. A cartridge mechanical seal is described for service access. Material and elastomer compatibility still need checking against the actual liquid rather than assuming that the QDLF suffix covers every corrosive application.
For the QDL8 size group, the catalog lists 5–11 m³/h flow, DN40 connections, motors from 0.75 to 7.5 kW and a 24 bar maximum operating pressure. Stage count determines the selected head. The standard motor specification includes IP55 protection and Class F insulation; higher ambient temperature or installation altitude may require derating.
SELECTION NOTES
Specify the operating duty
Provide flow, required pressure rise, inlet pressure, temperature and liquid chemistry. Confirm size and stage count, seal materials, electrical supply, ambient temperature and installation altitude.
Published limits may describe different configurations within a series. Confirm that the required operating conditions are valid together.
