Product Details

The Edwards EDC series is a new generation of rugged single-stage dry claw vacuum pumps. The new series of EDC dry claw pumps adopt innovative design and set a new industry benchmark for the claw pump market. This series of pumps is simple, durable, and has a strong dust and corrosive gas handling capacity, is the right choice for your application. These new dry claw pumps are built to meet the standards and quality required by customers, providing you with a cost-effective and reliable solution to meet your needs.
Innovative structural materials and coatings allow the product to operate reliably over its service life, even under harsh process conditions.

Durable and durable
The simple design can quickly overhaul the pump cavity, which is convenient for cleaning the suction cavity when the suction cavity is contaminated by the entrained product.

Silent operation

cylinder

Water-cooled cylinder, with large cooling area and good cooling effect; wide valve chamber and airway, small gas resistance, weak air flow pulsation; chrome-plated cylinder inner hole, good rust and corrosion resistance, good wear resistance;

Piston, piston ring, sealing ring

The piston is made of high-strength cast aluminum alloy with sufficient strength and rigidity. The piston ring and sealing ring are imported from TEFLON (filled with polytetrafluoroethylene) material; excellent in heat resistance, wear resistance, self-lubrication and chemical resistance; long life design and high reliability.

Cylinder head

The larger heat exchange area creates a very good cooling effect, better eliminates the heat generated by the suction and exhaust valves during operation, and effectively extends the service life of the entire unit.

Intake/Exhaust Valve

The valve seat and the receiving seat are made of stainless steel through precision dewaxing casting. The valve plate is made of Swedish ASSAB heat-resistant and wear-resistant special valve plate steel, which has a large flow area, small resistance loss, long life and high reliability.

Crankshaft/Bearing

Ductile iron crankshaft, high fatigue strength, good vibration absorption. The crank tip is high frequency quenched, good wear resistance; the balance is accurately simulated and calculated by 3D simulation software, small vibration. High strength heavy load bearings are used, fully adaptable to heavy loads, and can withstand long-term operation.

Connecting rod/ Crosshead

The connecting rod is made of high-quality ductile iron, which has high strength and good stability; the large-head open structure, I-shaped rod section, high compression stability; light weight, small inertia force. The crosshead is always kept vertical, ensuring oil-free air, and its reliability also guarantees the long life of the unit.
