Carver Pumps

Since we built our first pumps in 1938, Carver Pump has become recognized as one of the leading centrifugal pump companies, building pumps to the most demanding engineering specifications and military standards in the world.

We were one of the first American pump companies to attain ISO 9001 certification – the most recognized standard for quality in the world. This certification is your assurance that our commitment to quality includes not only our hardware, but also superior customer service, leading-edge R&D, and continuous improvement in everything we do.

So whether the job is refueling fighter jets on the deck of an aircraft carrier, supplying paint to an auto assembly line, or bringing water to the fountain in a city park, we put our reputation on the line everyday with every pump we build.

Carver GH End-Suction Centrifugal Pump

GH

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.

Carver Pump Ltd RS Multistage,Ring Section Pump

Multistage, Ring Section Pump

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.

Carver Pump Ltd RS Multistage,Ring Section Pump

For Pressures to 1,500 PSI

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.

Carver Pumps -855 Filtrate Pump, Close coupled and overhead Mounted Pumps

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 Pumps -855 Filtrate Pump, Close coupled and overhead Mounted Pumps

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.
