Standing guard for the safety of millions
From Europe to Australia, South America to the Far East, commercial, residential and industrial facilities around the globe are depending on Patterson fire suppression pumps and Pre-Pac® engineered self-contained systems.
Millions count on Patterson for their unparalleled knowledge and expertise in developing quality fire pumps and pumping systems that perform reliably when needed in office buildings, schools, dormitories, industrial sites, high-density residential areas, manufacturing plants and commercial sites.
All Patterson Fire Pumps and accessories are engineered to meet, or exceed, all applicable codes, including: UL and ULC listings, FM and NYBSA approvals, NFPA, VdS, LPCB, CNBOP and CE certifications worldwide and all NFPA-20 standards.
Horizontal split case fire pumps
Ideal for both high and low pressure pumping requirements Patterson Horizontal Split Case Fire Pumps are engineered for reliable operation upon demand. Patterson sweats the details
All fabricated parts are standardised 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.
The simple, split case design of these pumps allows for in-line service without disturbing piping while ensuring long, efficient unit life, reduced maintenance costs and minimal power consumption.
These pumps are designed to operate with pressures in excess of 390 psi (27 bar) and flows from 150 gpm to 5,000 gpm (568 litres/min to 18,925 litres/min).
Whether your fire pump application requires an electric motor, a diesel engine or vertical or horizontal orientation, these industry-approved pumps can be configured to meet your specific needs.
High pressure two-stage DMD fire pumps
Engineered for rugged, reliable service when space is at a premium High Pressure Two-Stage Fire Pumps are engineered to produce as much head as two single-stage pumps in series but in a much more compact size. Heavily built, they are highly dependable and have every mechanical feature to assure long life.
Design highlights include dual single-inlet, enclosed impellers, mounted back-to-back, and an interconnecting passage between stages. Bronze or bronze-bushed interstage pieces guard against wear.
Sizes range from 3-in. to 6-in. (7.6-cm to 15.2-cm) discharge for capacities to 1,000 gpm (3,785 litres/min) and heads to 1,150 ft (351 m).
V.I.P. vertical in-line fire pumps
Compact, self-contained design for easy adaptability to new or existing applications Patterson’s V.I.P. series of Vertical In-Line Fire Pumps offer a simple alternative to horizontal split case pumps in fire applications with lower flow ranges. Their unique design also minimises energy consumption while lengthening service life.
These fire pumps are easy to install into existing pipe lines. With the inlet and outlet on a common center line, only standard piping supports on either side of the pump are needed. This eliminates the need for costly foundations or pads.
The precision-cast impeller is dynamically balanced for smooth operation, and it is enclosed for optimum performance and long service life. Balance holes on the back side of the impeller reduce thrust with hydraulic balancing of the pressures.
Designed for durability, every pump has standard packing and a two-piece gland. Coupled to V.I.P.’s standard JP/JM motor, this quality, integral drive system features uniformity of tolerances, minimum shaft deflection and bearings sized properly for the job.
An integral clean-out port on the suction side enables cleaning without having to remove the driver, eliminating the need for a NFPA 6.3.4.1 Pipeline Strainer.
With pressure ratings from 40 psi to 150 psi (3 bar to 10 bar), Patterson’s V.I.P. Vertical In-Line Fire Pumps deliver flow ranges of 50 gpm to 1,250 gpm (189 litres/ min to 4,731 litres/min).
Vertical turbine fire pumps
Flexible staging enables capacity requirements in minimum floor space
Among the most versatile pumps in Patterson’s arsenal, the Vertical Turbine Fire Pump stands on Patterson’s more than 50 years of vertical pump expertise. Employing the latest design concepts and engineering technology, these pumps are ideal for fire fighting.
They can be staged as needed to meet specific pressure requirements, with lengths and construction adaptable to the application. And their space-saving vertical design minimises floor space requirements. 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. Open line shaft construction is standard; special metallurgies are available.
No priming is necessary to provide flows from 500 gpm to 5,000 gpm (1,892 litres/ min to 18,925 litres/min), with pressures in excess of 350 psi (24 bar).
End suction fire pumps
Deliver Patterson performance and reliability to new or existing installations
Choose from two configurations—frame mounted and close-coupled, which can be flanged or threaded. These pumps are engineered to last with a precision-cast, dynamically balanced and enclosed impeller that minimises vibration and maximises bearing life. Engineered for lasting integrity with standard packing and a shaft sleeve, each unit is hydrostatically pressure-tested to 1-1/2 times shut off before shipping.
Removing the rotating element without disturbing suction and discharge connections is easy because of
our unique, back pullout design.
Registered fits at the volute and volute cover maintain pump alignment.
Featuring pressure ratings from 40 psi to 150 psi (3 bar to 10 bar), Patterson’s End Suction Fire Pumps are available in flow ranges of 50 gpm to 750 gpm (189 litres/min to 2,835 litres/min).
