Process engineers – Lower your energy requirements with higher efficiency
The ZeroLoss Containment Shell is a revolutionary new feature offered on HMD sealless magnetic drive pumps. The containment shell was designed to dissipate heat, helping to prevent flashing and vaporization, two common sources of failure in magnetic drive, sealless pumps. Made from PEEK Composite material, the ZeroLoss Shell provides a more efficient and robust alternative to traditional metallic containment shells. ZeroLoss shell conversions are available for many HMD pumps originally supplied with metallic containment shells.
ZeroLoss Containment Shells are especially effective for light hydrocarbon applications (specific gravity between 0.4 and 0.6) – because they are susceptible to flashing.
Conversion available on all GSA/I Frame 1 / 2, GSP Frame 1 / 2 / 3, GSPV, GSPLF, LMV-801 and GSPX.
Key Benefits of the ZeroLoss Containment Shell:
- Increased efficiency and reduced power consumption
- Elimination of eddy current losses leading to significant energy savings and lower life cycle costs – reduced power consumption leads to potential payback within 1 to 3 years on energy savings alone.
- Reduced carbon footprint and enhanced environmental benefits.
- More robust design and optimized MTBF
- Complete elimination of inductive heating, reducing heat transfer into the process liquid reducing the risk of flashing, which is often the cause of magnetic drive pump failure.
- Improved handling of volatile and heat sensitive liquids.
- More resilient for closed discharge or potential dry-run scenarios.
- Improved margin-to-safety flash factor – reduced risk of premature failure.
- Increased time for operator intervention during system upsets
- Simple retrofit capability
- Easy, field installed conversion for existing units
- ZeroLoss conversion kit available as an Insurance Spares Kit option.
Key Technical Specs for the ZeroLoss Containment Shell:
- API compliant, 40 bar rated.
- Suitable for operating temperatures from -148° to 248°F (-100° to 120°C)
- Engineered from hi-tech PEEK (PolyEther Ether Ketone) Composite material.
- High electrical resistivity – leads to zero losses.
- High strength – 5X lighter than steel but just as strong.
- Inert to a wide range of chemicals.
- Not affected by sub-zero temperatures.
- Thermal shock resistant.
- Similar form factors to existing metallic shells.
Plant operators – Increase your MTBF
Made from Ceramic Matrix Composite material, the CMC thrust bearing is an alternative to the standard Silicon Carbide internal thrust bearing material. The CMC Thrust Bearing conversion is suitable for any operating temperatures and process liquids, and offers a more robust design solution for volatile and marginal pumping applications.
GSA/I Frame 1 / 2, GSP Frame 1 / 2 / 3, GSPV, GSPLF, LMV-801 and GSPX.
Especially suited for refining and chemical plants with:
- Services containing liquified gases or heat sensitive liquids.
- Low NPSHa applications or those with an increased risk of dry-running.
- The ZeroLoss Shell conversion is also recommended with CMC Thrust Bearing Conversion.
Key Benefits of the CMC Thrust Bearing Conversion:
- More robust design and optimized MTBF
- Mode of failure far more benign than the standard SiC / SiC internal being design.
- Improved handling of volatile and heat sensitive liquids.
- More resilient for closed discharge or potential dry-run circumstances.
- Low cost conversion opportunity
- Minimal replacement parts required, only the internal thrust bearing.
- Short lead time component.
- Simple retrofit capability
- Easy, field installed conversion for existing units.
- CMC Thrust Bearing conversion kit available as a Service Kit option.
Process and rotating equipment engineers will increase bearing life and pump reliability
To prevent oil over-filling on site and to enable bearing monitor devices to be fitted, HMD has developed a modular bearing housing for the HMD GSP pump range. The bearing assembly is designed to improve robustness, enhance the options available, and facilitate upgrading while being offered as an upgrade option for existing GSP pumps.
Available on GSP Frame 1 / 2 / 3 pumps
Especially well suited for refineries and chemical plants with sealless magnetic drive pumps with the following parameters:
- Sites with a history of over-filling bearing housings.
- GSP installations where alternative bearing seals or oil mist lubrication is required, or where external bearing monitoring (e.g. vibration and/or temperature monitoring) is required.
Key Benefits of the GSP External Bearing Assembly Upgrade:
- The new design prevents the risk of oil over-filling, increasing bearing life.
- Allows for alternative bearing isolators to be installed.
- Vibration sensor and temperature sensor provision supplied as standard, enabling these monitoring devices to be retrofitted.
- Includes provision for oil mist bearing lubrication.
- Optimized interchangeability.
- Modular design for quick and easy retrofit to GSP pumps in the field.
Maintenance made faster and simpler
HMD has developed a Hexagon Outer Magnet Ring (OMR) Drive as an upgrade option to the existing eccentric drive design. The upgrade allows for quicker re-assembly of the bearing housing during routine maintenance activities, reducing pump downtime. The Hexagon OMR Drive is a robust alternative to the eccentric drive design and may be the preferred option for process and rotating engineers.
GSA/I Frame 1 / 2 and GSP Frame 1 / 2 units
Key Benefits of the Hexagon OMR Upgrade:
- Hexagon OMR Drive preferred by customers as it is easier to re-assemble than an eccentric drive design, allowing for quicker bearing replacement and reducing downtime during planned maintenance activities.
- More robust than the eccentric drive design leading to increased MTBF.
- Upgrade can be completed quickly and easily in the field.
Sealless Magnetic Drive Pump Protection for Process Plants
Power Monitoring represents one of the best values available today to protect your pump from system upset damage and avoid costly shutdowns, unexpected repair costs, and premature equipment failures. A SundGard power monitor senses true power input and can be set to alarm or shut off if preset power limits are exceeded. By simply monitoring motor input power, nearly all pumping conditions that typically damage pumps can be quickly detected and avoided.
For use with any HMD pump
Detectable Pumping Conditions include:
- Dry-running
- Low Flow/Back-on-Curve
- Increased Viscosity/Precipitation
- Deadhead/Closed Discharged Valve➢ High Flow/End-of-Curve
- Jammed Impeller
- Severe Cavitation
- Decoupling (Magnetic Drive Pumps)
Key Benefits of the SundGard Power Monitor:
- Minimizes pump damage due to system upsets.
- Reduces downtime, service and spares parts costs.
- Integral current transformer eliminates extra component and installation costs.
- Provides valuable feedback to troubleshoot operational problems.
