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
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.

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 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).
