Edwards EDC1000 3Ph 400 V 50 Hz IEC-UL/cUL

Edwards EDC1000 – dry claw vacuum pump with 950 m³/h

The Edwards EDC1000 is the largest dry claw pump from Edwards: 950 m³/h at 50 Hz and up to 1140 m³/h at 60 Hz, connected via DN 100 flanges. The gearbox is separated from the oil-free pumping chamber by a labyrinth seal, and the claws run without contact. An inlet non-return valve prevents backflow into the process when the pump is switched off. In the 400 V version the pump measures 1468 × 680 × 1240 mm; the weight is between 615 and 791 kg depending on the version (tolerance ±10 kg, including oil). The noise level is 82 dB(A) at 50 Hz and 85 dB(A) at 60 Hz.

Typical applications

For the nEDC and EDC claw pumps Edwards names, among others, central vacuum systems, plastics extrusion, woodworking, vacuum conveying, pick-and-place, drying and degassing, printing and paper processing, medical technology, milking and milk transport, thermoforming and waste extraction.

Variants of the Edwards EDC1000

The EDC1000 is available from Ehrler & Beck in five variants (part numbers A50873210, A50873220, A50873230, A50873200, A50873201). The motor power ranges from 18.5 kW (400 V, 50 Hz) to 22 kW (380 V, for frequency converter operation from 20 to 60 Hz). Two variants are supplied without motor with a free shaft end. The 460 V 60 Hz version (IEC-UL/cUL) has the same motor as the 380 V version but is not designed for frequency converter operation.

Features of the EDC series

• Single-stage, dry (oil-free) claw pump; no mechanical contact between the claws, virtually maintenance-free
• Claws and rotor housing with a high-temperature-resistant coating against corrosion
• Built-in pressure control for continuous operation at 200 mbar; inlet non-return valve
• Modular design: gearbox separated from the pumping chamber by a labyrinth seal
• Silencer with drain valve integrated in the base; an external silencer can be connected in addition
• According to Edwards at least 30 % more energy-efficient than oil-sealed pumps; operation with a frequency converter possible
