Why do pumps fail?

Why do pumps fail?

According to a report by the Health and Safety Executive, mechanical sealimage 101s are widely regarded as the weakest point in any pumping system using them. They account for 80% of all pump failures, the remainder being leakage through static seals such as gaskets / O rings and bearing failure. It follows that if you eliminate the problem, you eliminate the failure.

HMD Sealless Pumps are magnetically driven, they have no mechanical seals, and only a
single, fully trapped gasket that ensures system integrity, even at high temperatures and
pressures.

 

What are the advantages of magnetic drive over mechanically sealed pumps?

  • The mean time between failure (MTBF) for magnetic sealless drive pumps is typically three times that of mechanically sealed pumps.
  • Double mechanical seals require support systems and barrier fluid. These require constant monitoring and maintenance to work properly. Sealless pumps are far simpler and no complex support is needed. HMD
  • Mechanical seals leak across their faces (that is how they work). Magnetic drive pumps are a true zero leakage design. This eliminates potentially harmful emissions and odours associated with sealed pumps.
  • Sealless pumps are easier to maintain, have fewer working parts, no potential leak paths and no support systems to worry about.
  • There is less cost involved in system design and procurement, and no concerns regarding material compatibility or appropriate buffer liquids.
