Product Description

Centrifugal Pump Theory and Standard or Nonstandard Stainless Steel Pump 


QDLF Stainless Steel Pump 

>>> Product Overview

Centrifugal pump theory and standard or Nonstandard stainless steel pump design enables the pump to be installed in a horizontal one-pipe system where the suction and discharge ports are in the same horizontal plane and have the same pipe dimensions. This design provides a more compact pump design and pipework.


All the parts touch with liquid made of 304 stainless steel, 316 stainless steel on request. The pump head and suction & discharge can be made of cast iron on request too.


>>> Application

 Centrifugal pump theory and standard or nonstandard stainless steel pump. It can be used to convey various medium from tap water to industrial liquid at different temperature and with different flow rate and pressure. easy to maintenance booster pump is applicable to conveying non-corrosive liquid, while QDL automatic single booster pump is suitable for slightly corrosive liquid.

  • Water supply: water filter and transport in waterworks, boosting of main pipeline, boosting in high-rise buildings.
  • Industrial boosting: process flow water system, fire fighting system.
  • Industrial liquid conveying: cooling and air-conditioning system, boiler water supply and condensing system, machine-associated purpose, acids and alkali.
  • Water treatment: ultrafiltration system, reverse osmosis (RO) system, distillation system, separator, swimming pool.
  • Irrigation: farmland irrigation, spray irrigation, dripping irrigation.

>>> Pump

QDL/QDLF is a kind of vertical non-self priming multistage centrifugal pump, which is driven by a standard electric motor. The motor output shaft directly connects with the pump shaft through a coupling. The pressure-resistant cylinder and flow passage components are fixed between pump head and inlet&outlet are located at the pump bottom at the same plane. This kind of pump can be equipped with an intelligent protector to effectively prevent it from dry-running, out-of-phase and overload.
