'Sealless Centrifugal Pumps' by Tom Marcone
(published on and in printed magazine)

Sealless Centrifugal Pumps Sealless pumps have an advantage over AODD pumps in clean chemical applications. While air-operated double-diaphragm (AODD) pumps are widely accepted and used in many applications, their use on clean chemical transfer can be argued as inefficient. The word clean is emphasized in this article. AODD pumps are monsters at pumping liquids that include viscous and dirty fluids. Clean chemical is defined as having particles under 50 microns in size and less than 5 percent by volume.

Most chemicals delivered by rail, truck or tote fit into this category. Many facilities that use AODD pumps on dirty or viscous processes will also use this technology on clean processes. The availability and familiarity of AODD pumps make them an easy choice for almost any application. Unfortunately, what is sometimes overlooked is the cost associated with running an AODD pump in an application in which a sealless centrifugal pump could be used. AODD pumps have three detriments—maintenance, pulsation and air consumption.

AODD pumps require preventive maintenance on their diaphragms and other wear parts. The wear items need to be replaced before a stated number of strokes occur. To replace the wear parts, the pump must be removed from the system. This may lead to downtime if a spare pump is not on hand, although having a spare pump on hand is an added cost. Once the pump is removed, a cost is associated with the replacement parts and the labor to rebuild the unit. Once rebuilt, the pump will require additional labor to be reinstalled. Pump rebuilding is not a one-time process. It must be rebuilt every time it approaches the defined maximum stroke limit.

AODD pumps are positive displacement pumps. Because of this, pulsation occurs when the diaphragm reciprocates. This pulsation causes pipe stress and vibration that must be monitored. Although pulsation dampeners can be installed to help alleviate the surges, this adds an expense.

Air Consumption
AODD pumps consume air, not electricity. The cost to generate and maintain air is increasing. Plant air is not free, and air compressors are expensive. They need to be maintained and can easily be maximized by other processes in the plant. Air compressors are also inefficient. Added to this inefficiency is the fact that air lines from the compressor to the pump can leak. The AODD pump also adds inefficiency to the process. Combine these factors, and the AODD pump can be one of the most expensive pumps to operate in a plant. Compared to an electrically powered pump, an AODD pump can cost as much as 75 percent more to operate on similar services.

Introducing the IX Series Advanced Metering Pumps

The IX Series are direct-drive, digitally controlled metering pumps combining both accuracy and flexibility into an energy efficient design.  Precise control is maintained over a wide output range, enabling one pump to satisfy a broad range of application flow rate requirements.  The IX Series meets today’s demands for automated chemical delivery in industries from wastewater treatment to chemical process.

The newest size expands the IX Series to a maximum capacity of 40 GPH (150 l/h) and a pressure rating up to 150 PSI (10 bar).  A turndown ratio of 750:1 enables only two models to satisfy most chemical metering applications. The advanced head design and fixed stroke length maintain a high compression ratio throughout each stroke, resulting in fast priming and no gas-lock conditions. Precise motor control coupled with an efficient check valve design creates accurate performance of +/-1% over the entire output range.  Average power consumption is only 62 watts!  Helical gears and return springs reduce power consumption by up to 70% compared to conventional motor-driven mechanical metering pumps.  The IX drive requires no oil bath or additional lubrication.  In fact, the drive is maintenance free over the life of the pump.

MXM series offers compact efficient solution for chemical pump applications.

Iwaki America Inc., Holliston, MA, announces the introduction of their new MXM series of magnetically driven, ductile cast iron lined, dry run pump designs. Incorporating their proven self-radiating bearing design and dry run rated non-contact system, this rugged compact process pump series provides proven technology for tough chemical handling applications.

The MXM series includes motor sizes from 2 HP to 5 HP, flows to 165 GPM and heads to 146 Ft. Back pull out design allows for ease of maintence. Modular construction with individually replaceable parts maximizes support flexibility. Uses standard NEMA c-face motors for versatility in installation options. MXM designs utilize a robust internal design ensuring maximum reliability under adverse operating conditions. Non-contact bearing system provides for dry run operation without damage to the pump. Self-radiating bearing system effectively transfers frictional heat from the bearing area to prevent damage during upset operating conditions. The MXM is another example of Iwaki's commitment to the continuous development of improved chemical pump technology with emphasis on quality, efficiency and performance. Think twice. Spec Once. These pumps are perfect for tank farm transfer, bulk chemical distribution, chemical filtration and circulation, general process pump service
