Impeller

According to stress a double volute type is adopted

toreduce radial force, ensuring limited bearing stress

Easy to instal. The pump cover can be automatically

aligned.

Relative position of inlet and outlet pipelines of motor

and pump body can be adjusted according to the

requirements ofthe user's site.

There is no vortex at inlet. Operation is stable with

lowloss.

Volute

Rolling bearing which is lubricated bygrease.

Easy to maintain. Bearing is enlargedto have a

long service life.

End bearing is installed with bearing sleeveand

key, which is fixed, reliable and easy todismount.

High quality mechanical seal without leakage.

Mechanical seal shaft sleeve is made of

stainless steewhich is resistant to corrosion and

is easily maintained.

Asbestos-free soft packings which meet

environmental requirements are used.

Injection type of soft packing which has the

function ofon-line maintenance is used.

There is no need to shutdown for maintenance,

which can avoid cost lossesassociated with

stopping production. Friction power lossis low

without leakage.

Advantages of motor:

According to requirements, KYSB can be equipped with 380V, 6kV and various types of protected (IP23, IP44, IP54) motors.

The Y2 series low-voltage (380V) motor can be used with a matching power of 630kW or less. It is a new type of high-quality

motor that is superior and of a higher grade than the Y series. It has an attractive appearance, low noise, a protection grade of

IP54, and an insulation grade of F (B grade assessment). Meanwhile, The Y2 series motors with a power of 315kW and below

also have installation interchangeability with the Y series (IP44) motors.

Explain of model name

The KYSB series of split-case single-stage double-suction centrifugal pumps is a new type of split-case double-suction pump independently developed

by our company based on market demands and extensive absorption of advanced technologies from similar products. Its notable features are:

a complete and universal type, excellent model, novel structure, and convenient maintenance.

At present, our company produces a wide variety of KYSB pump models, with over 40 types and nearly 400 basic specifications. By changing the basic

type to the improved impeller and cutting the outer diameter of the impeller, the type range of this series of pumps is full and wide, and the usage

efficiency is increased. Within the performance range of the type spectrum, we can provide pumps that appropriately meet the operating points of any

flow and head required by users.

The products have been meticulously manufactured and subject to perfect quality control, reaching the leading level in China. Our company has

obtained ISO9001 quality certification. The product quality can fully guarantee that this series of pumps comply with the standards of 1S02548C,

GB3216C and GB/T5657.

This product is widely applicable to urban water supply and drainage as well as urban water supply. Water supply and drainage for centralized heating

systems Steel and metallurgical enterprises, petrochemical refineries, paper mills, oil fields, thermal power plants, and airport construction.

Water supply and drainage for chemical fiber factories, textile factories, sugar factories, chemical plants and power stations; Water supply for fire

protection systems and air conditioning systems in factories and mines; Farmland drainage and irrigation, as well as various water conservancy projects.

Usage

Rotational speed :990,1480 and 2960r/min

Voltage :380, 6kV or 10KV

Inlet and outlet diameters :150-600mm(Flange dimensions comply with GB/T17241.6-1998)

Flow range :68-3975m ³ /h

Head range :6-230 meters

Temperature range: The maximum liquid temperature ≤80℃(-120℃); The ambient temperature is generally ≤40℃. The maximum working pressure

(inlet pressure + pumping pressure) is 1.0MPa(G)(Hsp≤75m) or 1.6MPa(Hsp>75). Special configurations can reach 1.6MPa(G) or 2.5MPa(G) respectively.

The medium that can be conveyed is clear water. If the medium is other liquids, please contact our company.

Sealed water pipe components: Do not install when the inlet and outlet pressures are ≥0.03MPa(G)

Structural design: Single-stage double-suction axial splined-case volute centrifugal pump, horizontally installed. The drive unit (electric motor or internal

combustion engine) can be set on the left or right side of the pump as required (i.e., facing the outlet).

The drive rotates counterclockwise on the left side and clockwise on the right side.
