Product Description

Performance parameters:

Applicable temperature range, installation size same as IS type single-stage single-suction centrifugal pump, applicable to ship water supply and drainage. The IS and CIS pumps are simple in structure, reliable in performance, small in size, light in weight and high in efficiency, low in noise, low in vibration, low in NPSH, and easy to use and maintain. IS and CIS pumps have a total of 29 basic models and hundreds of specifications, but only use four axes and four suspension components, and the degree of generalization of parts is as high as 92% or more.


Parameter range:

Flow  5.4 to 400m3/h

Head  4~125m


Model Description: 

CIS100-65J-200A

CIS--Single-stage single-suction centrifugal pump for ships

100--intake diameter (mm)

65--Outlet diameter (mm)

J--J indicates speed reduction

200--The nominal diameter of the impeller (mm)

A--A, B, and C represent the first, second, and third cuts of the impeller outer diameter, respectively


Structure type:

The pump is horizontally mounted with horizontal axial suction and spouting radially upwards. The pump is of the suspension type structure. It is not necessary to disassemble the inlet and outlet pipelines during inspection, and the rotor components can be taken out for maintenance. The pump is connected with the motor through ordinary elastic coupling or lengthened elastic coupling. The pump shaft seal adopts soft packing seal or mechanical seal. The bearing is a single row radial ball bearing and is lubricated with lubricating oil.


Rotational direction:

From the motor side, the pump rotates clockwise.

The main part material: The material of the flow passage part is generally ordinary gray cast iron.


Complete Scope:

Complete sets of pumps, motors, common bases, couplings, etc. Also available are bottom valves, check valves, and gate valves.

When ordering, please specify the material of the main parts. If there are special requirements for the pump and motor, please consult with the company about the technical requirements.


440V, 220V, 60Hz, 50Hz power supply can be configured according to customer requirements.
