Advertorial HOWTO: Solve These Common Pump Problems By KEN COMERFORD, Vice President, Vanton Pump & Equipment Corp. D espite the fact that the use of pumps for transferring water and other fluids goes back many centuries, there is no end to the creative new pump designs and the development of new materials of construction needed to meet the ever-changing fluid handling requirements of the process and related industrial manufacturing industries, as well as for the municipal facilities serving the water and wastewater treatment requirements of our expanding populations. Our company has been privileged to be involved in these growth and changing markets since the middle of the last century when we were asked to develop a unique pump to safely handle human blood during heart/lung surgical operations… and do it without contaminating the red blood cells. We did this successfully with the unique design of our FLEX-I-LINER® flexible liner rotary pump and the creative genius of chemical engineers who developed the many nonmetallic materials that made it possible for this same pump design to be used for hundreds of different aggressive chemicals. As these new plastic materials were developed, it was natural for them to be used in other pump designs, and of went on to develop a full line of horizontal and vertical centrifugal pumps to take advantage of their superior chemical inertness, abrasion resistance low weight and moldability. We now offer the most comprehensive line of thermoplastic pumps in the industry. But the plastic pump industry still faces a number of significant problems. Here are the major problems and what Vanton has done to solve them. 1. Product Contamination: All Vanton pump designs avoid any metal components in contact with the fluid. The wide choice of thermoplastics includes PVC, CPVC, PP, PE, PVDF, ECTFE and PTFE. Data are available on the suitability of the individual plastics for aggressive and ultrapure fluids, water, pharmaceuticals and semiconductor chemicals. 2. High Maintenance due to corrosion: The thermoplastics do not corrode. They have broad resistance to acids, caustics, solvents, chlorides and halogens. Maintenance costs are minimized. 3. Abrasion problems: The thermoplastics are ten times more resistant than the stainless steels and 80-100 times more resistant than fiberglass reinforced plastic. 4. Customizing: Vanton pumps are not provided off-theshelf. They are engineered to meet individual service conditions as described by the user. Delivery is fast and costs are minimal. Complete records of materials of construction and design features are maintained in permanent files to permit identical duplicate future orders. 5. Pump Seal Leakage: Vanton offers a full line of sealless pump designs. These include our Flex-i-liner rotary pump, vertical pump designs and horizontal magnetic driven centrifugals. 6. Technical Support and Experience: Although many technical articles on the thermoplastics and their applications have appeared from time to time in the trade press, Vanton is the only company that has dedicated its engineering staff to gathering information on the subject and sharing that knowledge and their experience, through creation of an on-going Technical Library of articles they have written and have been published. There are now 172 of these articles, reprinted for free distribution on request to pump specifiers, system designers, consultants, plant engineers, maintenance personnel, purchasing managers and engineering students. AN INDEX of the listed technical articles identifies them in numerical order and includes an alphabetical list of products pumped showing the numerical identification of the article or articles, which describes the installation. A separate alphabetical list of the companies, whose installations are described, identifies the specific articles by listing their numerical identification. If you specify, purchase, operate or maintain pumps for the handling of corrosive, abrasive, hazardous or high purity chemicals… or for the transfer of potable water or wastewater, there is no escaping one or more of the common problems described above. Vanton engineers and experienced sales force of over 400 representatives worldwide are at your service.
