Magnetically coupled internal gear pump for ultimate protection against leakage. ED is for Environmental Duty. As only minimal maintenance is necessary, ED pumps will be a very economical solution compared with traditionally sealed pumps, especially where the application requires the use of double mechanical shaft seals. Key features and benefits: - Reversible direction of flow with double acting relief valve option available - Directed coupled gearbox with NEMA or IEC electric motor eliminating alignment issues - Adjustable rotor end clearance without opening the system to the atmosphere - Torque capabilities in excessive of 800 ft-lb - Flow rates max. 90 m3/h with differential pressure up to max. 16 bar. - Iron, Steel and Stainless Steel construction - Tungsten Carbide abrasive wear materials are available for abrasive duty applications

The HD gear pump are specifically designed for difficult applications Heavy Duty - Internal gear pumps in cast iron, for a wide range of viscous, non-corrosive liquids. HD pumps are specifically designed for difficult applications and those involving high viscosity liquids. They are known by their sturdy and simple construction and available with 90° angular configuration. Key features and benefits - Flexible sealing options - “True” back pull-out design - Opposing inlet and outlet connections with oversized ports - Shaft supported by two ball bearings in single sealed configuration - Self-priming with large suction capabilities - Low NPSH requirements - Self-draining, integral safety relief valve - No speed reduction required in six smaller sizes - Complete heating/cooling jacketing available - 90 degrees Port Orientation
