Applications in NZ and the South Pacific Include:
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.
The API Maxum Series is Carver's offering specifically designed to meet the needs of the Hydrocarbon Processing Industry. Fully compliant with the latest edition API 610 specifications, the API Maxum is a horizontal, end suction - top discharge, centerline mounted unit. Designed for optimum reliability, these units feature rugged construction and state of the art mechanical design features. These units are well suited for applications that include petroleum refining/production/ distribution, petrochemical/chemical processing, boiler circulation/high temperature applications, and general industrial use. A workhorse in the industry, these pumps are designed for years of service, in some of the toughest environments imaginable. Created specifically for the Hydrocarbon Processing Industry, the API Maxum benefits other markets as well. Hydraulic performance extends to over 9,000 GPM and 720 feet of head. Capable of operating up to 400°F without external cooling and 600°F with cooling makes this pump ideal for mid-high temperature applications.
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.
The 855 Series is Carver's offering specifically designed to meet the needs of Filtrate Pump users. Since developed in the late 1950s at the request of a large Original Equipment Manufacturer (OEM) of vacuum filtration equipment, a wide variety of options are now being included as standards into each pump produced. Flange mounting directly to the receiver tank eliminates suction piping/NPSH problems and allows pumping to resume even after short periods of interrupted flow. Capable of operating in vacuum conditions up to 26" Hg, the specially designed semi-open impeller assures pumping from a trickle to full capacity.
Carver filtrate pumps can be used to replace Krogh pumps, which although widespread across the NZ pulp & Paper industry, Krogh have disappeared.
Capacities range to 1000 GPM, depending on discharge head and speed of operation. Available in 6 sizes ranging from 1”-4”; standard materials of construction include All Iron, CD4MCu and Rubber Lined. The 855Series features an overhead v-belt drive arrangement as a standard, with options for close coupled or frame mounted drives. By utilizing either belt drive or variable frequency drive, performance characteristics can be fine-tuned to match most system requirements. Maintenance is simplified as the vertically split case maybe disassembled to expose the entire wetted area. Standard features include a rotatable discharge casing which allows flexibility in locating desired discharge flange orientation, packed stuffing box with seal water connections provided to insure lubrication and eliminate vacuum/air leakage and 2” diameter stuffing box bore on all units. Pumps come with discharge flanges dual drilled for both 150lb / PN 10 connections. 17-4pHstainless steel shafts are utilized to both strengthen the shaft and eliminate the need for shaft sleeves (duplex shafts with CD4MCu). Impellers are keyed to the shaft ,providing a secure fit and protection should momentary reverse rotation occur. The Swing-Out Mount is popular as an optional feature, allowing inspection of the pump or quick access to the tank interior.
