Machining and Manufacturing Pumps
Duff has a broad range of pumps for industrial processes with built-in intelligence. Specifically, we can supply you with the industry standard in the machining industry, with high efficiency pumps for filtration applications; unsurpassed accuracy in machine tool applications; cooling and heating pumps to easily handle hot water and thermal oil; and reliable pumps for part washer applications.
If you are looking for a pump solution as reliable and accurate as it is efficient, Grundfos is the obvious brand to turn to. Grundfos’ thoroughly tested range of pumps targeted at machining processes is built on more than 60 years of experience and specifically developed to operate flawlessly and with great precision in even the most demanding applications. There’s a reason why Grundfos is the global No. 1 brand in pumps.
Grundfos MTR, SPK, CRK, and MTC pumps are vertical multistage centrifugal pumps designed for pumping of cooling lubricants for machine tools, condensate transfer and similar applications. The pumps are designed to be mounted on top of tanks with the pump stack immerged in the pumped liquid. Grundfos’ range of high-efficiency pumps offers unsurpassed accuracy and stability in a variety of machine tool applications, including:
- Grinding, Milling, Boring and Sawing
- Wire Cutting
- Spark Erosion
Depending on the specific application, the pumps can be customized to perfectly match every requirement. Grundfos’ multistage pumps are available in different lengths and with the exact pressure and flow required for different materials. Equally suitable for vertical and horizontal installation, the pumps even offer complete freedom in terms of design. Furthermore, the pumps can be optionally supplied with integrated frequency converters or an advanced E-solution to increase system efficiency and optimize processes, including lowering the heat input into the cooling lubricant.
Specifically for grinding and boring processes, Grundfos’ impressive range of high-pressure pumps includes models that efficiently handle up to 120 bar (1740 psi) – which is required, for example, with deep hole boring. The entire pump range targeted at machine tool applications is available in stainless steel as well as cast iron. These pumps can be equipped with special seal solutions, motors with integrated HAN10Es plug, motors for 50/60Hz drive as well as with motors for every possible voltage requirement.
Grundfos manufactures a line of pumps that are perfect for part washer applications, and which can be customized in terms of flow and pressure to accommodate individual requirements. The single-stage or multistage centrifugal pumps operate in temperatures up to 356°F (180°C) and at pressures up to 40 bar (580 psi) in two types of applications:
- Box washers
- Tunnel washers
On top of the range of standard pumps available for part washers, Grundfos also offers special pumps developed to handle different media. If the water contains oil, the shaft seal material must be able to withstand this specific liquid – while particularly aggressive detergents require that the pump material has been designed for this challenge.
Naturally, all pumps for part washers can be supplied with chemical dosing pumps that accurately dose the detergent and solvents.
Offering a vast variety of industrial pumps, Duff is the proven leader in the manufacturing industries, offering pumps specialized, for example, in the following industries:
- Plastic & Rubber
- Machinery & Equipment
Decades of experience allow Duff to cover every pumping requirement in new systems and in replacements, including all the utilities, and to handle even the most difficult challenges. Whether you are dealing with hot liquids, flammable or aggressive medias or high pressure, Duff is able to provide you with a dedicated solution that will keep the production running smoothly—day in and day out. This is true if you are faced with space problems or demands for increased energy efficiency.
If you are building a new system or production, we recommend that you talk to us as early in the development process as possible. By far the majority of pumps can be easily adjusted to match your specific requirements and optimize the entire system.
In addition to an impressive range of high-quality pumps, Duff offers a wide array of motors, speed controls and monitors that will efficiently optimize your machine tool processes – as well as your energy consumption.
Ask about the Grundfos integrated MLE motor with variable frequency drive (VFD), and whether it can be retrofitted to the pumps that you use. If so, we could help you realize substantial efficiencies and energy savings.
Duff offers machine tool specialists to assist you in any development process or problem-solving scenario.
Duff is always by your side—or by the side of your customer. Duff has emergency service 24 hours a day, 7 days a week. Plus, Grundfos is present in 45 countries, making expert know-how and support easily accessible in the local language.
