INTRODUCTION

- This manual contains the instructions for the 

C.S.F. centrifugal pumps of CN series relative to 

receiving, delivery, installation and maintenance.

The information given here in is of a general nature. 

Specific information for each version is given in the 

respective annexes.

C.S.F. INOX SpA reserves the right to amend or 

modify  the  content  of  this  manual  without  prior 

notice. This instruction manual contains the in-

formation necessary to understand and use the 

centrifugal pumps CN series produced by C.S.F. 

INOX SpA. We recommend reading this manual 

and keeping it for future reference in a safe place 

near the pump itself.

- When requesting information, replacement parts 

or assistance, always specify the pump type (*) and 

serial number (**) indicated on the identification 

plate, or the complete part number given in the 

purchase documentation.

SYMBOLS

SAFETY WARNINGS

When the pump is working the following occurs:

- Electric parts are in tension.

- Mechanical parts are moving.

- Pump body, pipelines and articulations are under internal pressure. Therefore do not remove any pro-

tection or locking, do not loosen screws or clampings, as this can cause serious damages to persons or 

objects. 

The clamp joining the pump casing and the cover must be well tightened and it should not be 

easily unscrewed by hand. 

- Non-observance of inspection and maintenance can cause damages to persons and objects, especially 

when dangerous or toxic liquids are pumped.

- When pumping liquids at a temperature over 60°C, adequate protection and warning signals are requi

-

red.

- When you buy a pump with bare shaft, motor coupling operations have to be carried out according to 

technical directions and law, providing adequate protections for joints, gear belts, etc.

- Operations on the electric parts have to be carried out by skilled personnel, according to technical direc-

tions and law, on authorization of the responsible installer.

- Installation must ensure an adequate ventilation, in order to cool the engine, as well as enough space 

for maintenance operations.

Before carrying out any operation which requires to disassemble the pump (inspection, cleaning, seal 

replacement, etc.), the following preliminary operations have to be carried out:

- switch off engine tension and disinsert electric connection;

- close valves on suction and outlet pipelines, in order to avoid the risk of inundation;

- use adequate protections for hands and face, if the pump contains liquids which are injurious to health 

(for example acids, solvents, etc.);

- consider if the liquid which flows out of the pump when disassembling is dangerous and arrange for 

adequate safety measures.
