FRU series (Roots pump)

Based on the simple technology, they are made of a couple of Five lobes rotating in opposite directions in a stator.

Due to the lobe shape of the rotors and to the synchronization of their rotation through a pair of gears,

these rotors remain permanently tangent to each other and tangent to the stator. FRU series is suited

to a wide range of vacuum applications combined with primary vane pumps, piston pumps or dry pumps.

Atmospheric pressure

Designed by-pass valve structure, when used with a backing pump, they reduce pump downtimes

and energy consumption, and protect the motor from damage as you do not need an external pressure switch

Stable performance

Without sealing fluid in the cylinder, these pumps use vapor flux which is for especially ideal clean environments

Usage for the vertical and horizontal outlet port

FRU1440, FRU2880 can be assembled both vertical or horizontal outlet port to streamline your system,

vertical flow prevents condensation from accumulating inside the pumping chamber adapted to environments.

Simplified maintenance and Easy exchanging parts

'On-site' repair and maintenance capability and easy exchange Inlet/Outlet port, motor flange designed in compliance with ISO standards

Low noise

Rotor with Five-lobe can reduce noise and vibration, precision ground gears contribute to the smooth, quiet operation

Applications

Semiconductor processing, vacuum metallurgy, vacuum drying, vacuum distillation, freeze-drying,

vacuum simulation, Low-density wind tunnel, Pharmaceutical, vacuum impregnation
