Introduction
This manual deals with the installation, operation and maintenance of VOGT S.A. L
series centrifugal pumps.
This model is a multistage centrifugal pump, with closed impeller, radial flow with
horizontal axis, cylindrical diffuser type casing, with lateral horizontal suction and
vertical discharge upwards. The suction and discharge ports are for nominal pressures
PN-16 and PN-40, PN-64 according to DIN 2543, DIN 2545, DIN 2546 respectively.
The operation of a centrifugal pump, chosen in accordance with all the technical background, can give poor service for
various reasons. This is generally due to poor installation and/or operation of the pumping equipment.
Efficient service is only achieved by installing and operating the pumping equipment correctly, therefore, the instructions
in this manual must be fully complied with. Pumps should not be used for purposes other than the service conditions
stipulated at the time of purchase.
The nameplate attached to the pump describes the most important features of the equipment purchased.
The design, materials, and workmanship incorporated in the construction of VOGT pumps allow for a long, trouble-free
service life. The life and satisfactory performance of VOGT pumping equipment, in any case depends on a correct
application, installation and also on a periodic inspection and careful maintenance.
VOGT S.A. will not be responsible for physical injury, damage or other inconvenience caused by improper installation,
operation or maintenance.
The warranty is only valid when the equipment is used for the application for which it was ordered.
In case of any doubt or additional information regarding the installation, operation or maintenance of the pumping
equipment, contact qualified technical personnel by calling the head office or any authorized distributor.
VOGT S.A., reserves the right to make changes at any time without notice and without incurring any obligation.
The contents of this publication are based on the latest product information at the time of going to press.
No part of this publication may be reproduced without written permission from VOGT S.A.
This manual should be considered a permanent part of the pump and should remain with the pump if sold.

Safety
Instructions
Indicates a procedure, operation, etc., with a strong possibility of severe personal injury, loss of life or irreparable
damage to equipment, if not performed properly.
Indicates a procedure, operation, etc., with a strong possibility of severe damage to the pumping equipment, if not
performed properly.
THE CONTENTS OF THIS MANUAL MUST BE READ AND UNDERSTOOD BEFORE INSTALLING AND OPERATING THE PUMPING
EQUIPMENT. CAREFULLY READ AND UNDERSTAND THE MOTOR MANUAL, ATTACHED TO THIS MATERIAL, PROVIDED BY THE
MOTOR MANUFACTURER, BEFORE OPERATING THE PUMPING EQUIPMENT.
•Learn how to stop the pumping equipment quickly and understand the operation of all controls. Do not allow
pumping equipment to be used without proper instructions.
•Never place your hands, feet or any part of your body near rotating or moving parts.
•Never operate the pumping equipment if any protection of the rotating parts is missing.
•Never operate the equipment without first charging and verifying the correct oil level in the bearing body, in
models that use oil lubrication.
•To ensure the correct lubrication of both bearings, it is required that the equipment is correctly leveled
(horizontal).(horizontal).
•Always keep the pump at least one meter away from building walls or other equipment during operation to avoid
fire and to provide adequate ventilation.
•Always perform inspection before starting the pump. In this way you can avoid an accident or damage to the
equipment.
•Children and domestic animals should not go near the place where the pump operates, let alone touch it, because
they could be injured by touching the equipment activated by the motor.
•Never place flammable items such as fuel, matches, etc., near the pump while it is running.
•Never place objects or items of any kind on the motor or pump, as this may create a fire hazard.
•Always maintain good cooling air circulation if the pump is to be operated in a small room.
