1. Description

KN series non-clogging water pumps are the single stage, axial suction and cantilever non-clogging centrifugal pump. There are four types of impeller for selection.‘B’ impeller - closed non -clogging impeller;‘D’ impeller -closed multi-vane impeller;‘E’ impeller -open impeller;‘Z’ impeller -free-flow impeller.
Typical application

It is specially used for the city water supply, the sewage and effluent treatment, chemical, iron&steel industries and the paper,sugar & caned food industries. It can deliver all kinds of sewage, clear water, seawater, bittern water, waste water and sludge so that it can be used in water supply plant , sewage treatment works, breweries, mines as well as the chemical and construction industries. Type KN pump normally is suitable for delivering the neutral media( PH value is 6-8 about ). For the application of corrosive fluid and other special requirements, please quote this information when making order.
2. Features

●  High efficiency, Non-clogging, Reliable operation, Little vibration, Low noise, Easy maintenance.
● The series KN pump is supplied with 4 kinds of impeller for selection.
   ‘B’ impeller-closed non-clogging impeller.
   For clear water, the sewage and fluids containing solids and sludge which do not liberate gas.
   ‘D’ impeller-Closed multi-vane impeller
   For clear water, the fluid containing slight suspension such as treated sewage, screen water, pulp water,sugar juices,and so on.
   ‘E’ impeller-Open impeller
   Same applications as ‘D’ impeller but also including fluids containing air.
   ‘Z’ impeller-Free-flow impeller
   For fluids containing coarse solids liable to bunch or plait(such as long fiber admixtures, sticky particles and so on)and fluids containing air.
● Shaft seal:
   Gland seal:there are two kind of design:standard’s and high-temperature’s.
   The high temperature type should be used when the temperature is higher than 90℃.
   The stuffing box of this type can be cooled in order to be suitable for the transporting duty in high temperature.
   Mechanical seal: It also can be used for the application where leakage is not allowed.
● Drive:
   In general, they are directly coupled. Type are also indirectly coupled with belt, the range of drive ratio is from 1:1 to 1:2.
