Industry
From the government to the armed forces to councils and local utilities the supply of reliable, 'fit for purpose' pumps and meters is critical. We can offer expertise and experience on a broad spread of applications and solutions and access to the following global leading manufacturers:
Weir Minerals pump division Warman, produce the world's leading slurry pumps. The SP and SPR range of vertical slurry pumps are true cantilevered designs. They incorporate extremely wear resistant metals or polymer covering to withstand abrasion.
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.
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.
Grundfos offers a wide range of dosing pumps representing state-of-the-art technology.
Digital Dosing solutions (SMART Digital, DME, DDI) set new standards in liquid chemical handling and accuracy. The operator can easily install and set up the pump to discharge exactly the quantity of dosing liquid required for the process in a unique drive- and flow-control management concept. The setting of the pump is displayed in ml/h, l/h or gph, and the operation mode is easily identified by means of icons.
The DMH mechanical hydraulic dosing pump range is the preferred choice for industrial and complex tasks. The DMH range is a series of extremely strong, robust pumps for applications where a substantial dosing range and high-pressure capabilities are required
The dosing pumps are designed for handling chemicals within the following applications, among others:
Heavy Duty fully transportable engine driven pumps for a wide range of applications. QP Aussie pumps are designed for local conditions and the range is extensive enough to cover applications.
Fire Fighting Pumps - Designed to out-perform and out-feature all other portable firefighting pumps, the Aussie Fire Chief is the flagship of the Aussie series. The range includes 2” and 3” fire fighting pumps delivers flows to 510 lpm (litres per minute) and heads to 98 metres.
Trash Pumps - Rugged trash pumps in 2”, 3” and 4” with flows to 1800 lpm, heads to 27 metres and suction lift to 7.6 metres. The pumps feature a big front mounted 'cleanout' port and high SG, cast iron, non clog style, open impeller and volute system designed to pump solids in suspension and resist wear.
Transfer Pumps - Aussie gushers (transfer pumps) are available in a range of sizes from 2” to a massive 6″ inlet/outlet. Designed to be ultra reliable, these pumps have applications in the transfer of high volumes of liquid at relatively low pressures. Flows of up to 2900 lpm, (QP602) with heads of up to 33 metres.
Sulzer are the trusted manufacturer of 'process pumps' for critical industries such as petrochem.
