Horizontal Split Case
HSC Pumps are engineered for reliable operation upon demand. All fabricated
parts are standardized and accurately machined for true alignment, increasing
overall durability. Precision balancing of all rotating components provides
mechanical dependability, reliable operation and minimal maintenance. Impellers
are constructed with double inlets that practically eliminate end thrust while
boosting operating efficiency.
These high-efficiency units operate with
pressures in excess of 390 psi (27 bar), produce heads to 750 ft (229 m) and
flows from 150 to 5,000 gpm (568 to 18,925 litres/min). They are available with
electric, diesel, or dual drive power and vertical or horizontal orientation.
Their simple, split case design allows for in-line service without disturbing
Vertical In Line
The compact, self-contained design of Sentinel™ Vertical In-Line Fire Pumps makes them easily adaptable to new or existing applications. They are a great
alternative to Sentinel HSC Fire Pumps when lower flow ranges are needed,
minimizing energy consumption while lengthening service life.
With the inlet and outlet on a common center line, these pumps are easy to install with simple mounting requirements—only standard piping supports on either side of the
pump. This eliminates the need for costly foundations or pads.
ratings from 40 to 150 psi (3 to 10 bar) deliver flow ranges of 50 to 1,250 gpm
(189 to 4,731 litres/min). Every pump has standard packing and a two-piece gland for durability
Featuring pressure ratings from 40 to 150 psi (3 to 10 bar) and flow rates from 50 to 750
gpm (189 to 2,835 litres/min), Sentinel™ End Suction Fire Pumps are available in
two configurations—frame-mounted or close-coupled, which can be flanged or
threaded. These pumps ably bring Patterson’s rugged performance and reliability
to existing applications or new installations.
Their ease of installation
minimizes foundation and mounting complexity—you simply add standard piping
supports. And thanks to our back pullout configuration, it’s easy to remove the
rotating element without disturbing suction and discharge connections.
Among the most versatile pumps in Patterson's arsenal, the Sentinel™ Vertical Turbine Fire Pump stands on our more than 50 years of vertical pump expertise. Because it embodies the latest design concepts and engineering technology, this pump is
ideal for fighting fire.
Flexible staging enables these units to meet capacity requirements in a minimum of floor space. Standard construction offers cast iron discharge heads with a fabricated steel column, stainless steel head and bowl shafts, or alloy steel line shaft and cast iron bronze fitted bowls. Special metallurgies are also available.
No priming is necessary to
provide flows from 500 to 5,000 gpm (1,892 to 18,925 litres/min), with pressures in excess of 350 psi (24 bar).
