Indentification of safety instructions

Non complience of safety instruc-

tions identified by the following 

symbol could affect safety for 

persons 

Safety instructions where 

electrical safety is invol- 

ved are identified by: 

Safety instructions which shall be considered 

for reasons of safe operation of the pump 

or pump unit and/or protection of the 

pump or pump unit itself are marked 

by the sign: 

Introduction

A screw pump from IMO is a quality product that is designed for a long problem free operation in tough environ-

ments. As all other mechanical products they do however requires a certain grade of maintenance and service in 

order to guarantee a faultless and economic favourable operation.

A recommendation is to go through the pump each 5 year in order to replace wear details such as ball bearings and 

certain gaskets and o-rings. A relatively small review of a screw pump from IMO means that the pump in most of 

the cases will be in a condition “as new” and therefore give the operator another long and problem free operation.
