- Xylem GV Variable Speed Booster Sets
The Lowara GVF series booster sets are fully automatic booster sets for water supply. They are equipped with 2-6 pumps (where one can be a jockey pump), pressure transmitters and control panel with a SD60 controller and a variable frequency drive, all mounted on a frame for easy installation.
One pump is speed controlled and the rest operates at full speed. With the SD 60 controller it’s easy to set and check the performance either on site or remote via Modbus or internet.
Specifications
- Delivery: up to 750 m³/h
- Head: up to 160 m
- Power: up to 37 kW
- Maximum operating pressure: 16 bar
The GS range of fixed speed booster sets includes models with 2 to 3 electric service pumps, and an additional jockey pump able to adapt to specific requirements within different applications. The start and stop of the pumps is based on the pressure values set on a pressure transducer, in order to deliver the water required. One pressure transducer is connected on the delivery side of the set.
A second one is connected but only as a reserve device. With the cyclic changeover function, duty assignment is rotated to ensure both pumps remain active and with even running hours, so wear is uniform and the use factor is reduced for longer pump life. This system also ensures continuity of operation, in case one of the pumps needs maintenance. The electric pumps used in the GSD range are FHE and SHE series and SV series vertical multistage pumps.Pumps are controlled by an electric control panel with a new electronic card with display on the front door. The electronic card and panel can also be used for waste water applications with up to 3 pumps installed
The Lowara Varispeed booster systems are suitable for mains water supply systems in buildings and facilities.They provide constant pressure thanks to the SD60 controller, the new main board that controls the number of pumps running and the speed of each pump. A Lowara Varispeed booster system includes pumps from the high-efficiency SV range and frequency converter in the panel. The booster set range consists of two to six SV pumps which are fitted on a common base with all components, pipes and fittings assembled. One pressure transducer is connected on the delivery side of the set. A second one is connected but only as a reserve device. The Varispeed system ensures instant control, flexibility, efficiency and energy savings. Thanks to its simple design and shape, the Varispeed booster systems are suitable for all types of installation where space is limited. Achieving constant pressure in the system ensures low maintenance costs, high quality operation, and cost savings. Lowara Varispeed booster systems establish high quality, value and new technologies that work together in a highly efficient system.

Specifications
Lowara Varispeed booster systems
are equipped with SV series vertical
multistage pumps. These high efficiency
pumps with EFF1 motors offer higher
efficiency and energy savings. The
reliability and efficiency of the SV series,
combined with the new SD60 controller,
ensures we provide the best solution for
our booster systems. Thanks to the SD
60, the brain of the Varispeed booster
systems, it is possible to control up to six
pumps, their speed and the number of
pumps in run.
SD60 is linked with a frequency converter
(one for the set or one for each pump)
in order to achieve flexibility and full
control of performance output. In this way
it is possible to ensure constant water
pressure all the times.
Varispeed booster systems are used when
additional pressure and flow is required.
The huge range of Varispeed models is
developed in order to meet all customers’
demands forperformance, control and
system monitoring.
Applications
Water supply
The Lowara Varispeed booster systems
are suitable for water supply systems
and for boosting pressure in high-rise
buildings, hospitals, schools, hotels,
public buildings, industrial premises,
theatres and camp sites, where the
demands of water change frequently and
at different times of the day.
Lowara booster systems ensure the
reliability of the system, maintaining
constant water pressure for all users and
all day.
Irrigation
Lowara Varispeed booster systems are
able to satisfy the demand from an
irrigation system, such as in agriculture,
public parks and green areas, where
constant pressure is required. They
are especially suited to irrigation golf
systems. In line with irrigation software,
they can optimise the flow demands
for each zone and the pressure value to
sprinklers during the irrigation cycle.
Through the SD60 controller it is possible
to integrate with irrigation software in
the user’s PC to control performance and
adjust parameters when necessary.
