Supplies for Centrifugal Pumps
Select the appropriate accessories and supplies for centrifugal pumps
In centrifugal pump design, there are essential components and supplies for centrifugal pumps. Some of these include the actual pump, motor, accessories and auxiliary components. The main parts of centrifugal pumps consist of a stationary component (volute) and a rotating element (impeller). Motors are important components that are available in various horsepower and kilowatt ratings. Likewise, these pumps require different accessories and auxiliary components such as control valves, drains, wear rings and mechanical seals.Whether you require accessories and supplies for centrifugal industrial pumps, centrifugal water pumps or pumps for different applications, there are vendors that can meet your business needs. When buying supplies for centrifugal pumps, some options you may consider are:
1. Choose the correct horsepower motor for industrial centrifugal pumps.
2. Determine the type of impeller design (closed, open, semi-open or vortex) you need for an application. A closed impeller will require wear rings.
3. Find a centrifugal pump manufacturer or distributor that offers auxiliary components and accessories.
Look at pump curves to select the motor for a centrifugal pump application
It is important to select the correct motor size for a centrifugal pump. Some centrifugal pump manufacturers may provide pump curves for different size products. A pump curve gives the performance characteristics of centrifugal pumps. On these curves, important variables are the total dynamic head, efficiency, brake horsepower, net positive suction head and the capacity. Using these charts, you can select the best motor size for an application. Another factor for the proper selection of motors is the specific gravity of the media pumped.
Try: State Supply is a distributor of Bell&Gosset pumps and replacement components that include motors, motor mounts and pump accessories. Centrifugal pumps are available in a variety of horsepower; call or fax for a quote on centrifugal pump prices. Franklin Electric carries end suction centrifugal pumps and replacement parts that include motors. ChemicalProcessing.com provides a good article on motor selection for a centrifugal pump.
Select the right impeller and supplies for centrifugal pumps
Centrifugal pumps can be classified in different ways such as by flow type, suction type and on construction type (opened, closed, etc). The number of stages for a pump depends on the number of impellers. Vortex pump impellers are suitable for string media but are not as efficient as other designs. Semi-open and open have less probability of clogging, while closed impellers, which have sidewalls that enclose the vanes, require wear rings. Wear rings should be replaced when the clearance between the impeller and the casing doubles to avoid vibration problems.
Try: Alternate Source Parts offers a variety of centrifugal pump parts like impellers, wear rings, shafts, sleeves and stuffing box covers; part for ANSI and API pumps are also available. Pump Components also carries a wide selection of pump parts including different types of impeller design and wear rings. You can search for components by item description.
Buy accessories for a centrifugal pump
Centrifugal pumps may require mechanical seals, seal kits, bearing assemblies, or different types of valves. Whatever your business need may be, look for suppliers that have good inventories of different types of accessories and supplies for centrifugal pumps. You should compare both prices and products from different vendors before you make a final selection.
Try: Go to G&O Thermal Supply for bearing assemblies and seal kits. AB Industrial Equipment offers centrifuge pumps, mechanical seals and valves.
- To keep centrifugal pumps functioning properly, the three main areas to look at are lubrication, alignment and seal replacement. Be sure to see the manufacturer's recommendations as to the kind of lubricant needed for the equipment, and how often to lubricate the pump parts.
