GPMD & GLMD mag drive pumps- cost-effective pumps

GPMD/GLMD magnetic coupled pumps are mid-capacity mag drive pumps. These hermetically closed-coupled pumps are available in PP and ETFE (GPMD). The cast iron casing of the Verdermag GLMD mag series is ETFE lined.

In most cases, concentrated chemicals are stored in tank farms, located away from the production facilities, for safety and logistic reasons. The GPMD/GLMD magnetic coupled pumps are used to pump materials from to and from the separate sites, as the range is leak free and, therefore, the safest option. The media pumped by Verdermag GLMD/GPMD pumps are chemical liquids such as

• Hydrochloric acid
• Sulfuric acid
• Nitric acid
• Phosphoric acid
• Bases, including sodium hydroxide and potassium hydroxide

Features and benefits Verdermag GPMD/GLMD pumps

• 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, no packing and 100% leak-proof

Verdermag models GPMD and GLMD

 

Verdermag Model GPMD

The GPMD mag drives are excellent pumps for the transfer of chemicals in the mid-flow ratio. They are available in both Polypropylene (PP) and ETFE. Standard connections come with a threaded flange, and slotted holes to accommodate DIN, ANSI and JIS contra-flange specifications. The P components are injection-molded with glass fiber reinforcement.  ETFE mag drive models are reinforced with carbon fiber, and are suitable to numerous chemical types. 

Model GLMD mag drive

The stationary ceramic shaft design avoids 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 has self-lubricating properties if process flows are reduced. 

Application areas

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

With a flow range of 1300 (1500 for GLMD) l/min and a temperature of up to 90 °C, Verdermag drive pumps offer a complete solution for pumping chemicals. The Verdermag magnetic driven GPMD and GLMD series fulfill transport of fluids and chemicals in all regions of industry.
