GPMD & GLMD mag drive pumps; value for money

GPMD/GLMD models are mid capacity mag drive pumps with a very good price to quality relation.

The storage of concentrated chemicals is predominantly in tank farms located outside of the production facilities for safety and logistic reasons. The GLMD/GPMD magnetic coupled pumps are used to pump these liquids into the plant, where the liquids are used for production.

Examples of chemical applications

• Hydrochloric acid
• Sulfuric acid
• Nitric acid
• Phosphoric acid
• Sodium hydroxide
• Potassium hydroxide

Features and benefits Verdermag GPMD/GLMD pumps

• 100% leak free
• Eddy Current losses of max. 2% (GLMD)
• Magnet coupling of Samarium Cobalt (> 4 kW at 50 Hz) or Barium Ferrite (< 4 kW)
• All mag drive pumps are close coupled
• The GPMD mag drives have threaded flanges
• GLMD mag drives are metal lined and have fixed flanges
• Sealing is done by only one (1) static o-ring in Viton® (optional EPDM)
• No glands or packing: leakproof.
• GPMD models are manufactured in PP and ETFE.
• GLMD models are manufactured in an ETFE lined cast iron casing.

Verdermag models GPMD and GLMD

Verdermag Model GPMD

The GPMD mag drives are excellent pumps for the transfer of chemicals. They are available in both Polypropylene (PP) and ETFE. Standard connections are threaded flange with slotted holes to accommodate DIN, ANSI and JIS contra-flange specifications. Thread connections are also available. The PP components are reinforced with injection moulded fibreglass.
ETFE mag drive models are reinforced with carbon fibre. Most chemicals can be transferred with these material options.

Model GLMD mag drive

The stationary ceramic shaft design avoids a complex internal design as the single sleeve bearing is fitted into the internal magnet. The standard material for this sleeve bearing is high density carbon, which can be self-lubricating if process flows are reduced.
The front and rear casing of the verdermag GLMD are sealed by just one (1) static o-ring in Viton.
The injection moulded ETFE components, such as the front casing liner, rear casing, impeller and internal magnet are reinforced with 20% carbon fibre to give optimum strength and temperature resistance.

Application areas

• Chemical Industry
• Pharmaceuticals
• OEM
• Tank emptying
• Food processing

With a flow range of up to 1300l/min (1500 for GLMD) and a temperature of up to 90°C the Verder mag drive pumps offer a low maintenance, reliable solution for the pumping of chemicals across a wide range of industries.
