Pumps, re circulation systems and controllers for domestic and commercial building services from the most trusted manufacturers in the world:
Available as either a frame-mounted (GHF) or close-coupled (GHC) unit, the GH is based on the same product platform as our vertical pumps and shares many of the same parts.
For added simplicity, the entire series is covered by only three bearing frames and comes in whole pump or modular kit form. The GHC is fully compatible with standard, off-the-shelf NEMA JP and JM frame motors, and all models feature a back pull-out design and casings rotatable in 90° increments for different field piping orientations
Other common features for the GH include 316 SS shaft sleeves, keyed impellers to prevent accidental spin off, dynamic balancing to ISO G2.5 guidelines, and re re greaseable bearings secured with locking rings, as standard. These features combine to produce shaft deflection values so low that they exceed the requirements of ANSI B73.1M-1991 and overall, provide some of the most efficient hydraulics in the industry.
Options for the JP include replaceable wear rings, cartridge seals, and flush plans. Along with these, higher alloy material options such as Ni-Al-Br and CD4MCuN and a full range of motor and baseplate choices are also available.
Our process duty, horizontal ring section multistage pump. Designed for moderate to high-pressure pumping, the RS is available in seven basic sizes with overall performance to 2,600 HP.
The RS is offered with Class 300 ANSI R.F. inlet flanges and Class 600 or 900 ANSI R.F. discharge flanges, depending on the pressures and number of stages involved. Hydraulic performance extends to 2,000 GPM and 3,400 ft. TDH, making it ideally suited for the most demanding industrial and process applications.
The RS design incorporates a product-lubricated, advanced composite material, sleeve-type radial bearing at the outboard (discharge) end. The thrust bearings are two matched angular contact ball bearings located at the inboard (suction) end of the pump. An optional outboard mechanical seal with an inboard radial ball bearing is also available. The RS has oil-lubricated ball bearings, which can be water cooled. Larger units can also be fan cooled.
The available materials of construction, from ductile iron to duplex stainless steel, offer combinations suitable for all applications from general water services to light abrasives and corrosive applications. Our proprietary advanced composite material, available for wear rings and interstage bushings, offers high-temperature performance, and exceptional resistance to wear and corrosion.
Nomad polypropylene air operated double diaphragm (AODD) pumps offer the following technical advantages:
