7 Reasons Why HMD Sealless Pumps are the Smart Choice for Chemical Applications

If your company is involved in chemical processing, here are 7 reasons why you should consider using HMD Sealless Magnetic Drive Pumps:

Legacy

HMD Invented Sealless Magnetic Drive Pumps

HMD Kontro was founded in 1946 as Hydraulic & Mechanical Developments, Ltd. One year later (1947) HMD pioneered the first sealless magnetic drive pump in Eastbourne, UK and shortly afterwards, supplied the first ever HMD pump to ICI chemicals for a hot oil application.

Since delivering the first ever sealless pump over 75 years ago, HMD has led the way in manufacturing sealless magnetic drive pumps, supplying thousands of units into harsh and hazardous applications across the chemical, general industrial, refining and oil and gas industries.

Safety

HMD’s High Integrity Sealless Design Eliminates Leaks, Offering the Safest Solution for Hazardous Chemicals

For applications that involve very low or high temperatures, high pressures and volatile, toxic or aggressive liquids, sealless magnetic drive pumps have become a preferred alternative to traditional sealed pumps. With no seals, HMD sealless pumps eliminate potential leak paths and any risk of fugitive emissions that can harm productivity, employees and the environment.

Tried & Tested Secondary Control and Secondary Containment Solutions

For processes involving especially hazardous chemicals, Secondary Control or Containment options are available for the CSA/CSI and other HMD pump ranges that assure complete safety and emissions control, by providing additional safeguarding against any breaches of primary containment.

Since introducing secondary sealing options over two decades ago, HMD has been at the forefront of secondary protection design in the sealless pump industry, delivering numerous pumps with true Secondary Control and Containment.

Secondary Control provides an intermediate level of protection and ensures any leakage through the primary shell is restricted, and Secondary Containment provides the highest level of security and safety, by ensuring that any leakage is fully contained within the confines of the pump.

Advantages of HMD Secondary Control and Containment solutions:

• Fully independent secondary system that ensures separation of failure modes between primary and secondary containment
• No risk of overheating between the primary and secondary pressure boundaries
• Facilitates leakage monitoring within the secondary casing area to detect breach of primary containment
• Compact design with minimal impact on the overall pump footprint
• Easy to decontaminate the secondary casing in the event of primary containment failure

Affordability

Lifecycle Costs are Lower with HMD Sealless Pumps

• Initial Capital Costs – HMD’s sealless design removes the need for procurement of seals and seal support systems, helping to keep upfront costs to a minimum. The new CSA/CSI pump range has been designed with cost-efficiency in mind, providing a price competitive sealless pump solution that benefits from industry-leading design features, quality, safety and performance.
• Operating Costs – With the sealless design and elimination of mechanical seals and their support systems, HMD pumps have zero consumable items and lower operational costs than mechanical seal pumps, with no seals to replace or barrier fluids to replenish, treat or dispose of. The HMD ZeroLoss containment shell option provides additional operational savings through the removal of shell induction losses and reduced energy costs compared with sealless pumps containing conventional metallic shells or cans.
• Commissioning – HMD pumps are easier and less expensive to install and commission, from the elimination of seal cooling / flushing system piping, less instrumentation and DCS configuration, and reduced documentation / HAZOP requirements.
• Maintenance – The simple design of HMD pumps means they can be serviced and repaired on site with no need for special tools or specialist operator expertise, reducing costs associated with repairs and downtime. HMD pumps feature non-wearing internal bearings and have negligible spare parts consumption, further reducing maintenance costs.
• Total Cost of Ownership – Selecting an HMD pump helps lower other lifecycle costs. Examples of these include the costs associated with un-planned downtime and loss of production, which are minimized with HMD sealless pumps through the increased reliability and site serviceability, and the leak-free design with no risk of fugitive emissions eliminates any environmental / clean-up costs.
