High Pressure Two-Stage DMD Fire PumpsEngineered for rugged, reliable service when spaceis at a premium.High Pressure Two-Stage Fire Pumps areengineered to produce as much head as twosingle-stage pumps in series but in a muchmore compact size. Heavily built, they are highlydependable and have every mechanical featureto assure long life.Design highlights include dual single-inlet,enclosed impellers, mounted back-to-back, andan interconnecting passage between stages.Bronze or bronze-bushed interstage piecesguard against wear.Sizes range from 3-in. to 6-in. (7.6-cm to 15.2-cm)discharge for capacities to 1,000 gpm (3,785litres/min) and heads to 1,150 ft (351 m).High Pressure Two-Stage DMD Fire Pump.Dynamically balancedimpellers are mountedback-to-backReplaceable packing boxbushing protects casingfrom packing wearDeflectors preventwater from enteringbearing housingsHeavy-duty ball bearingsmounted in dust-proofcartridges protect thebearings when rotor isremoved from the casePre-drilled and tappedpacking box drippockets for removal ofpacking box leakage6
V.I.P. Vertical In-Line Fire PumpsCompact, self-contained design for easyadaptability to new or existing applications.Patterson’s V.I.P. series of Vertical In-LineFire Pumps offer a simple alternativeto horizontal split case pumps in fireapplications with lower flow ranges. Theirunique design also minimizes energyconsumption while lengthening service life.These fire pumps are easy to install intoexisting pipe lines. With the inlet and outleton a common center line, only standardpiping supports on either side of the pumpare needed. This eliminates the need forcostly foundations or pads.The precision-cast impeller is dynamicallybalanced for smooth operation, and it isenclosed for optimum performance and longservice life. Balance holes on the back sideof the impeller reduce thrust with hydraulicbalancing of the pressures.Designed for durability, every pump hasstandard packing and a two-piece gland.Coupled to V.I.P.’s standard JP/JM motor,this quality, integral drive system featuresV.I.P. Vertical In-Line Series Fire Pump.uniformity of tolerances, minimum shaftdeflection and bearings sized properly forthe job.An integral clean-out port on the suctionside enables cleaning without having toremove the driver, eliminating the need for aNFPA 6.3.4.1 Pipeline Strainer.With pressure ratings from 40 psi to 150psi (3 bar to 10 bar), Patterson’s V.I.P.Vertical In-Line Fire Pumps deliver flowranges of 50 gpm to 1,250 gpm (189 litres/min to 4,731 litres/min).Balance holes onthe back side ofthe impeller reducethrust with hydraulicpressure balancingThe precisioncastimpelleris dynamicallybalanced forsmooth operationEnclosedimpeller designensures optimalperformanceand service lifeIntegral clean-outport on suction sideenables cleaningwithout having toremove the driver,eliminating needfor NFPA 6.3.4.1Pipeline Strainer7
