The sealless pump eliminates a key source of leakage, and is therefore used when there is a need to contain highly toxic, dangerous and/or valuable fluids.
The driven shaft and impeller are completely contained in the pump chamber which is sealed by static seals such as gaskets or O-rings. This is in contrast to other centrifugal pumps where the pump chamber is sealed through a mechanical seal which is often a high maintenance leakage source.
The power is transmitted to the driven shaft using two main methods:
• Canned Motor Type Pump
• Magnetic Drive Type Pump
EngineeringCircle constantly evaluates the world’s suppliers of sealless pumps, and brings our users a shortlist of experienced manufacturers so purchasers know they are dealing with only the best suppliers and manufacturers on the globe. For more about sealless centrifugal pumps see our pages on Canned Motor Pumps and Magnetic Drive Pumps.
Sealless Pump components vary depending on the design conditions, design code and reliability requirements (amongst other things). Typical components which need to be considered at the time of purchase include the following, which are usually expressed in the form of a technical data sheet (available upon request from EngineeringCircle.com):
