1.05 Manufacturer's Qualifications


A. Equipment under this section shall be furnished
by a single supplier.


B. The supplier shall have the sole responsibility
for proper functioning of the system and equipment supplied.


C. Equipment shall be products that the manufacturer
regularly produces.


D. Manufacturer shall have in place a quality assurance
program.


E. Manufacturer shall have thirty years manufacturing
and pump system application experience.


F. Manufacturer shall have a facility capable of testing
the specified system at design flow and system pressure. Facility shall
be capable of providing suction pressure throughout the specified range.


1.06 Warranty


The SyncroFlo internal multistage pumping assemblies
and pressure regulating valves shall be guaranteed for one year from
date of shipment against defective material and workmanship. The motors
shall also be guaranteed for one year from date of shipment against
burnout from any cause when equipped with the pumping system manufacturer's
over-temperature protection and maintained according to instructions.


The complete pumping system shall be guaranteed in
writing by the manufacturer for a period of one year from date of startup
or eighteen months from shipment, whichever comes first, against defects
in design, materials, or construction. Warranties and guarantees by
the suppliers of various components in lieu of single-source responsibility
by the manufacturer will not be accepted.


1.07 Spare Parts


Ship the following spare parts with the system: 1
pint of touchup paint, spare control power fuses, and spare light bulbs.


PART II. PRODUCTS


2.01 System Performance


A. Attributes


1. Normal Operation


The lead pump shall start based on system pressure.
Lag pumps shall be sequenced on and off by an insertion-type paddlewheel
flow sensor. As backup, lag pumps shall be sequenced on and off by the
low system pressure sensor.


Automatic sequencing shall include the following features:



Successive and 24-hour alternation of equal capacity
pumps
Pump overlap during 24-hour alternation
Lag pump exerciser function
Sequential pumps starts and stops
Minimum run and stop delay timer for each pump
Field adjustable time delay for low system pressure
start signals

2. Low Flow Operation


Provide pressure sensor and a flow sensor to automatically
control lead pump operation. These controls shall prevent lead pump
short-cycling while maximizing the stored water available from the HydroCumulator
tank.


3. Emergency Alarms and Control


Automatic alarm sequencing shall include the following
features:



Sequence shifting that adjusts the pump sequence when
any pump is disabled
Each pump shall have a t</span><span class="Normal--Char" style=" font-size: 12pt;

Sequencing to reduce hydraulic or electric surges
after power restoration or alarm reset
All pumps shall stop and require manual reset in the
event of low system pressure, high system pressure, or low suction pressure
alarm condit</span><span class="Normal--Char" style=" font-size: 12pt;

B. Code Compliance


All packaged equipment shall be Nationally Recognized
Testing Laboratory (NRTL) certified as a packaged pumping system suitable
for the intended use in accordance with OSHA Federal Regulations and
National Electric Code (NEC) Article 90-7. Safety certification label
shall be permanently attached to pump system.


C. Factory Prefabrication


The entire booster system shall be factory prefabricated
on a structural channel or I-beam steel stand with all interconnecting
piping and wiring completed and operationally tested prior to shipment.
The assembled package shall also include lug type butterfly or full
port ball valves for isolating pumps. Suction and discharge headers
shall be stainless steel. Header piping connections shall be flanged.
All discharge-side piping shall be rated for the specified maximum suction
pressure plus pump shutoff pressure. Tubing for pressure switches and
gauges shall be copper with brass isolation valves. The only field connections
required will be to the suction and discharge headers, and the power
connections at the control panel.


D. Factory Test and Certification


The factory shal
