The Warrender sealless retrofit pumps are units designed to upgrade existing mechanically-sealed pumps to a sealless design, often using a magnetic drive or canned motor to eliminate the mechanical seal and its potential for leakage and maintenance issues. These retrofit solutions offer benefits like enhanced safety by preventing hazardous fluid leaks, increased reliability, reduced maintenance costs, and can often be installed without significant piping or foundation modifications. 

• How They Work
  Sealless retrofit pumps replace the mechanical seal with a barrier that completely contains the fluid: 
  • Magnetic Drive: Power is transferred from the motor to the pump impeller using two sets of magnets (one connected to the motor, one inside the impeller) separated by a static barrier.
  • Canned Motor: A double containment shell surrounds the internal workings of a motor and pump, creating a sealed unit that eliminates the need for a mechanical seal.
  

• Key Benefits
  • Leak Elimination: The primary benefit is eliminating leaks associated with mechanical seals, enhancing safety and environmental protection.
  • Reduced Maintenance: Eliminating seal wear parts and seal maintenance can significantly lower operating costs and downtime.
  • Increased Reliability: By removing a common point of failure, sealless designs offer greater reliability.
  • Improved Safety: Double containment, especially in canned motor designs, provides enhanced safety for hazardous or high-pressure applications. 

Common Applications:

These retrofit solutions are ideal for a wide range of industries and applications, including:

• Chemical Processing: Handling corrosives, solvents, and toxic fluids.

• High-Temperature Services: Applications where traditional seals may struggle.

• Hazardous Fluids: Ensuring containment of materials that pose an environmental or safety risk.

• Reactor Circulation: As seen in the nuclear industry, to prevent leaks of critical fluids.
