Mining

As specialists in WARMAN pumps we are also proud to offer the WEIR range of knife gate valves, including the USA made Delta range and more cost effective ISOgate range. The range also includes pneumatic pinch valves, mining quality check vales (non return) and the Autoball AB3 valve.

‍

There are a number of processes within a mine site which require specialised valves designed to handle highly abrasive environments.

Delta Industrial™ knife gate valves are ideal for many of these demanding processes.

Mill circuit

The mill circuit presents a number of issues when selecting a valve. Large particle sizes, high percentages of solids, and high specific gravity make selecting the correct valve critical to achieving the least possible downtime. We can customise our Delta Industrial™ valves to provide optimal performance in any part of the mill circuit. The Delta Industrial™ 15 series and Centre, Block and Bleed (CBB) valves provide outstanding isolation performance, with zero leakage shut-off and no discharge to the nvironment during operation.

Tailings and slurry transport

Tailings consist of ground rock and process effluents that are generated in a mine processing plant. Mechanical and chemical processes are used to extract the desired product from the run of the mine ore and produce a waste stream known as tailings. The pressure in these lines can exceed 50bar (725psi), necessitating engineered valve solutions for safe and reliable operation. We have developed the Delta Industrial™ 60 series valves for such applications, being capable of handling 102bar (1480psi).

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.

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

Lubrication & Circulation Pumps

Tuthill lubrication pumps handle a wide range of viscosities and sustain a constant flow at any pressure.

Standard Metering Pumps are engineered to safely measure and dispense preset batches of product from drums and tanks. The unique design eliminates the need for scales and pails as product can be metered directly out of your source vessel. Available in both Industrial and Sanitary configurations.

Standard Pump motors are designed to operate in the most demanding of environments. An extensive line ofExplosion Proof, TEFC, Open Drip-Proof and Air motors provide durability and safety regardless of the environment.

Our complete range of pump tubes provide an ideal solution for applications ranging from corrosive chemicals to light oils. Pump tubes are available in Polypropylene, PVDF, CPVC, Stainless Steeland Aluminum.

Blackmer® offers Ebsray® RC Series regenerative turbine pumps to the Americas market for LPG (propane) and Autogas applications. Regenerative turbine pumps are also known as peripheral pumps or centrifugal regenerative pumps.

Recognized as a global leader in Autogas handling applications – with decades of reliable performance in thousands of installations worldwide – Ebsray regenerative turbine pump products are known for efficiency, reliability, and performance.

Ebsray RC Series regenerative turbine pumps have been specifically designed and precision-built for high-pressure transfer in Autogas applications. The secret to the success of these pumps is the innovative impeller design, which optimizes hydraulic performance resulting in high differential pressures even at low flow rates, a critical consideration for Autogas applications. Ebsray turbine pumps also feature a smooth, quiet operation and long pump life.

LEWA diaphragm and plunger pumps, which are reciprocating positive displacement pumps, provide the greatest possible metering accuracy. They set the standard for safety, reliability and efficiency, especially when it comes to pumping supercritical fluids.

Every metering pump made by LEWA is designed with particular strengths: Whether your needs include energy-efficiency, low maintenance costs, or an extremely long service life for diaphragms. Or perhaps you are looking for a metering pump model that can handle supercritical fluids and liquid gas, or one that meets the highest requirements and demands of the oil and gas, chemistry, cosmetics, pharmaceutical and biotechnology, or food and beverage industry.

An air operated diaphragm pump (also known as AODD pump or membrane pump) is a type of positive displacement pump that uses compressed air as a power source. The compressed air is shifted from one chamber to the other by a linked shaft that allows the chambers to move simultaneously. This back-and-forth motion, forces liquid out of one chamber and into the outlet manifold, while filling the opposite fluid chamber via the inlet manifold. Upon changeover, the fluid section that was filled on the previous shift empties into the outlet manifold and the fills the opposite chamber via the inlet manifold. The rapid changeover allows for reduced pulsation at the outlet.
