7. Cost – Total cost of ownership determined by multiple factors such as initial price, rated flex life for the application and costs of downtime and diaphragm replacement labor. Because of the many variables involved, advice from an outside expert distributor can greatly assist in selecting the best performing, most cost-effective option for individual applications.

There are general guidelines and points to consider when choosing the correct configuration. In parallel with these recommendations, it’s always advisable to check the manufacturer’s specifications and chemical compatibility guides. The first guideline is to remember to identify the temperature limits of all components in the pump. The internal pump components may be rated to an extremely low or high temperature, but that does not imply that the pump body material is rated to the same level, and vice versa. When configuring an AODD pump, it’s important to identify the temperature ratings of all components, by referring closely to the manufacturer’s product specifications. Increasing the working temperature has a significant consequence on material selection. For example, plastic pump bodies are not recommended because cold flow and creep can lead to leaking. As temperatures rise above 80°C, the choice of compatible internal components further decreases. At these elevated temperatures, materials such as ethylene propylene diene monomer rubber (EPDM), polytetrafluoroethylene (PTFE), polyvinylidene fluoride (PVDF) and fluoroelastomer (FKM or Viton®) are preferred. FKM and EPDM have the highest heat resistance, rated to 160°C and 135°C respectively. Next in line are PVDF and PTFE, rated to 107°C and 100°C respectively. At the other end of the thermometer, glycol transfer pumps are required to withstand cold environments down to −20°C, thus requiring aluminum, stainless steel, EPDM, FKM and Santoprene. Key points: • For high temperature applications: Stainless steel or aluminium pumps with FKM, EPDM, PTFE or PVDF wetted materials. • For low temperature applications: Stainless steel or aluminium pumps with EPDM, FKM or Santoprene wetted materials.

Flexible-tube or flexible-hose pumps handle slurries, high-viscosity fluids and abrasives, can be run dry, and have excellent self-priming capabilities. Pulsations are present in the discharge line due to the nature of the pumping mechanism.

Shaft configurations: In wet-bearing designs, the shaft is supported from above the mounting plate using antifriction, grease-lubricated bearings in the pedestal, and is additionally supported from below the mounting plate with product-lubricated sleeve bearings. The choice for the outer bearings includes ceramic, silicon carbide, siliconized carbide, carbon-filled PTFE and glass-filled PTFE. For extreme conditions, the shaft journals (or inner bearings) are constructed of ceramic materials. Wet bearing designs tap fluid from the pump discharge and route it to each bearing, since the upper wet bearings are not flooded when the liquid level is low. When the pumped fluid contains solid particles that can damage the wet bearings, an independent clean-water flush must be used.

David Rozee explains how they work, and how their low-maintenance application is proving cost-efficient for both businesses and the environment

Advice and experience will guide the farmer to establish how long before anticipated rain spraying should be carried out, how fast the tractor can be driven without spoiling the application to the crop and avoiding the spray being drifted away.

After ensuring the sprayer is in good working condition, calibration must be carried out for each application.

Dover has completed the acquisition of the All-Flo Pump Company, Limited business, which is now part of the Pump Solutions Group (PSG) unit within Dover’s fluids segment.

NPSHa is the amount of NPSH that the system has available at the eye of the pump impeller. This NPSHa value is entirely a function of the liquid, its properties, ambient conditions and the suction system design and geometry. Essentially, the calculation is about the suction system itself and has nothing to do with the pump. This calculation should be completed by the system owner, the end user and/or their engineer or consultant. For liability reasons, manufacturers are normally directed to not be involved in the customers’ calculations; however, as time marches on, the manufacturer is getting more involved mostly as a preservation issue.
