Durco® Mark 3™ Iso Mag Magnetic Drive Chemical Process Pump

Simplify installation, provide maximum safety, minimize total cost of ownership and more with Durco Mark 3 ISO MAG pumps.

Durco Mark 3 Iso Mag Magnetic Drive Chemical Process Pump

Flowserve now offers the Durco® Mark 3™ ISO pump with a sealless magnetic drive to meet your hard-to-seal chemical process needs. It’s well-suited for applications involving the movement of acids and other hazardous or toxic fluids

There can be no one-size-fits-all approach to safety, so we offer three configurations of the Durco Mark 3 ISO MAG pump: CBMM Long Coupled; CBME Close Coupled for fluids up to 350oC (662oF) without cooling; and CBME Heat Barrier for fluids up to 400oC (752oF) without cooling. Each configuration comes in 32 sizes

Heating/cooling jackets are available for high- and low-temperature applications. In addition, two back pullout options make maintenance safe and easy, while three containment shell selections (Alloy C-4, High-efficiency Alloy C-4 and Ceramic no eddy current losses) feature 1:1 interchangeability.

The Mark 3 ISO MAG pump complies with ISO 2858, ISO 5199, ISO 15783 and CE standards. Models that comply with the following directives are also available:

  • ATEX II 2G T1–T5 (2014/34/EU)
  • CUTR

Target industries

  • Basic Chemical
  • Fine and Specialty Chemical
  • Petrochemical
  • Pharmaceutical

Maximum safety

Ensure personal and environmental safety in hazardous and/or toxic conditions. Seal-less magnetic drives provide leak-free performance across a wide range of applications. High quality containment shells, in three material selections, combined with secondary control ensures that even in the case of containment shell damage, the pump will handle hazardous liquids safely and reliably.

Simplified installation

The Mark 3 ISO Mag pump can replace any ISO standard (2858, 5199 & 15783) sealed pump already in service as a direct 1:1 swap out. For tight clearance locations, the closed coupled design with its compact footprint can be used to save space. Both features allow customers to quickly replace “bad actor” pumps that are causing environmental or safety issues without significant effort.

Reliability and efficiency

Flowserve engineered the Mark 3 ISO MAG pump to operate over long periods between maintenance and to reliably operate in extremely low and high temperatures. Three containment shell options give our customers tremendous operational flexibility, energy efficiency and cost savings.

Minimized total cost of ownership

The modular design of the Mark 3 ISO MAG pump features standard and contained back pullout options. Long-lasting magnets, maintenance-free slide bearings and different options to maintain the pump help to avoid unplanned downtime and costs.

Market-leading delivery times

Durco Mark 3 ISO MAG pumps with a sealless magnetic drive are available in four weeks in the bare shaft configuration and in six weeks in standard configurations.

Advancing Safety: Rupture Discs for Sanitary Applications

From ipegstl.com

If you’re in the pharmaceutical, biotech or food and beverage industry, you know the importance of protecting your equipment, vessels and systems from overpressurization. In many cases, a rupture disc is the most advantageous of pressure relief devices. It’s precise, leak tight and cost effective.

There are many types of rupture discs, and facilities operating with sanitary and hygienic applications must find rupture discs that are manufactured in accordance with specific codes, standards and approvals. The SANITRX HPX product family from Continental Disc Corporation is one of the most advanced lines of rupture discs available. It has a proven performance in excess of five million cycles, operating up to 95% of burst pressure.

Improve Energy Efficiency with VFD Technology

From ipegstl.com

We turn off the lights when we leave the room. We turn down the A/C when we go on vacation. We turn off the water faucet when we’re not using it. So why are many companies running their pumps at full speed when it’s not needed?

Variable Frequency Drives

Variable frequency drives (VFD) reduce the total energy cost and life cycle cost (LCC) of an industrial pump, fan or compressor. The load profile for any industrial motor varies depending on multiple factors such as weather conditions and facility usage. VFDs are often a good choice for motors that don’t need to constantly run at 100%. They are able to monitor demand and change the motor output to match the load profile, ultimately making the motor more efficient and increasing energy savings. Also, VFDs help reduce the life cycle cost of a motor when it isn’t running at full speed at all times.

Read this article from Yaskawa to learn how to determine if a VFD motor is the right fit for your application. If you’re looking to speak to someone about your specific needs, contact OTP or ask the OTP experts.

Premature Seal Failure in Your Heating Hot Water Pump?

From ipegstl.com

Seal Failure

How is the heating hot water (HHW) pump working in your building? Do the seals seem to wear out far too quickly? Does it always look black when you open it, as though it is burnt on the inside? I have seen these symptoms on a number of occasions—usually in older buildings. What typically happens is that the same parts are put back into the pump, and six months later the seal is leaking again. Our objective at IPEG is to always increase the mean time between failures of your pump, particularly if we are aware there is an ongoing problem. We will look at options, materials of construction, type of pump and other possible factors.

The first thing to do is assess the problem before it is possible to find a solution. If there is premature seal failure, there are always several questions to answer. . .

Clean in Place (CIP) Vs. Clean Out of Place (COP) Sanitary Pumps

From ipegstl.com

There are many levels of “cleanliness” with regard to the sanitary pump market, and the requirements to achieve these levels and certifications vary.  Making the correct decision on which pump technology best fits an application requires some basic information, such as:

  • Fluid (product pumped)
  • Cleaning Process
  • Hygienic Requirements

Wright Flow Technologies offers three pump models to cover various hygienic levels.  These models are: TRA10, TRA20 and Revolution . . .

From ipegstl.com

Although magnetic drive pumps (mag-drive pumps) have been around for almost 70 years, it wasn’t until recently that the general industry lowered their resistance and started embracing the use of mag-drive pumps. Plant managers, engineers, and maintenance supervisors all had the same arguments for why they would not use mag-drive pumps in their plants:

  • Mag-drive pumps are too expensive
  • Catastrophic failure upon “dry-run”
  • Pump and part deliveries are too long

There was no arguing of these points a decade or two ago, but today things have changed. Corporations are looking at additional key driving points than just the initial cost of the pumps. Safety, environment, skill set and reliability are now part of the decision making process.Today the reverse arguments can be made to the above . . .
