GENERAL DESCRIPTION
PRODUCT DESCRIPTION
A Flowtronex Silent Storm Variable Speed
Pumping System is custom built to the
requirements provided by the purchaser. The
Silent Storm pumping system is a modular
variable speed system designed to maintain a
constant discharge pressure while providing a
variable flow rate to match the water demand of
the system. The system minimizes power
consumption by combining a variable speed lead
pump with constant speed lag pumps. The Silent
Storm utilizes a microprocessor-based controller
to efficiently manage pump operation to match a
wide range of pressure boosting applications.
Silent Storm Variable Speed Pumping Systems
are self-contained, pre-assembled and factory-
tested pumping plants. Silent Storm utilizes state
of the art technology, yet employs a simplistic and
straightforward design that makes installation,
operation, and maintenance an easy task, even for
the most inexperienced of operators.
This manual serves as a guide to understanding
the features of Silent Storm Pumping Systems and
provides a quick and clear reference for answers
to most questions pertaining to its service. Every
attempt has been made to explain all facets of
system operation and maintenance. However,
should you have specific questions not addressed
in this manual, you are encouraged to contact your
nearest Flowtronex Authorized FlowNet
representative, or the factory (800-786-7480
Ext. 3).
