PUMA WP 4500 B2

Busch PUMA WP 4500 B2 – Roots vacuum pump (vacuum booster)

The Busch PUMA WP 4500 B2 is a Roots vacuum pump (vacuum booster). The nominal pumping speed is 4500 m³/h (50 Hz) or 5400 m³/h (60 Hz). Nominal motor rating 11 kW (50 Hz) or 12.6 kW (60 Hz).

Features

• Reliable: solid rotary lobes, robust design in ductile iron GGG40
• Powerful: high volumetric efficiency, according to Busch up to ten times the performance of the vacuum system, for rough and fine vacuum
• Flexible: can be flanged directly to the system in any position, increases the performance of all types of backing pump, control via pressure switch or frequency converter
