Edwards EH4200 Mechanical Booster Pump

IN STOCK

The Edwards EH4200 is a high-capacity mechanical booster pump designed to enhance vacuum system performance by significantly increasing pumping speed in the pressure range of 0.01 to 50 mbar. Utilizing the Roots principle, it requires a suitable backing pump to operate effectively.

Key Features:

Hydrokinetic Drive: The EH4200 incorporates a unique hydrokinetic fluid drive that enables operation from atmospheric pressure, leading to faster pump-down times and eliminating the need for pressure switches, bypass lines, or variable frequency drives.
High Pumping Speed: It offers a displacement of 4,140 m³/h at 50 Hz and 4,985 m³/h at 60 Hz, making it suitable for applications requiring rapid evacuation.
Robust Construction: The pump features a high-quality, oil-free pumping mechanism with rotors and shafts made of corrosion-resistant cast iron, ensuring durability and reliability.
Automatic Overload Protection: Designed for safe operation, the EH4200 includes automatic overload protection to prevent damage under varying load conditions.
Cooling Requirements: The pump bodies of the EH4200 are water-cooled, with a recommended cooling water flow of 6 litres per minute.

Technical Specifications:

Motor Power: 11.0 kW (15 hp
Oil Capacities:
– Coupling cover: 6.5 litres
– Shaft seal reservoir: 0.45 litres
– Gear case: 3.5 litres
Weight: Approximately 481 kg (1,058 lbs)

Applications:

The EH4200 is ideal for industries requiring high pumping speeds and reliable vacuum performance, such as:

• Vacuum metallurgy
• Vacuum distillation
• Steel degassing
• Thin-film coating
• Vacuum impregnation
• Oil drying and degassing
• Space simulation
• Pharmaceutical freeze-drying
