1. Overview
The purpose of this manual is to provide the necessary
information for proper installation, operation and maintenance of
the pumps/electric pump units. The instructions and warnings
provided below concern the standard version, as described in
the sale documents. Special versions may be supplied with
supplementary instructions leaflets. Please refer to the sale
contract for any modifications or special version characteristics.
Always specify the exact pump/electric pump unit type and
identification code when requesting technical information or
spare parts from the Sales and Service department. For
instructions, situations or events not considered in this manual
or in the sale documents, please contact the nearest Lowara
Service Center.
2. Product Description
Information for installers and users
The SV range features vertical multistage non-self priming
pumps which can be coupled to standard electric motors.
In the 1, 3, 5, 10, 15, 22SV series, all the metal parts that are in
contact with the water are made of stainless steel. They are
available in different versions according to the position of the
suction and delivery ports and the shape of the connection
flanges. In the 33, 46, 66, 92, 125SV series, some of the metal
parts in contact with the water are made of stainless steel,
others are made of cast iron. A special version is available, in
which all the metal parts in contact with the water are made of
stainless steel. If you have bought a pump without an electric
motor, make sure that the motor used is suitable for coupling to
the pump.
3. Applications
Information for installers and users
These pumps are suitable for civil and industrial water
distribution systems, irrigation (agriculture, sports facilities),
water treatment, boiler feed, parts washing, cooling - air
conditioning - refrigeration and firefighting applications.
3.1 Working Limits
3.1.1 How to Read the Pump’s Rating Plate
The drawings in section 11, Fig.A and Fig.B, show the
essential data found on the rating plates for electric pump units
and pumps.
3.1.2 Pumped Liquids, Pressures, Temperatures
This pump can be used to pump cold water, hot water, water
with glycol.
The rating plate in Fig.A provides information regarding the
gasket and mechanical seal materials (whose representation is
depicted in Fig.B).
