UV4
Rotary Vane Vacuum Pump
Since 1923 Pneumofore has designed and produced vacuum pumps featuring original solutions, the result of constant efforts in research and development.
The UV vacuum pumps are easy to install, to operate fully automatically and represent the most simple and inexpensive solution for vacuum plants. UV pumps achieve a high degree of vacuum through a wide pressure range of practically constant flow. This allows performances equal to larger size pumps, with considerable energy savings.
The success of the UV series vacuum pumps in many industrial applications is based on the low life cycle cost, safety, environmental compliance, low noise level, compactness, high performances, design simplicity, reliability and durability.
UV4
Components
Main Features
Intake air filter with polyester cartridge (3 urn).
Coolant filter cartridge for lubrication circuit.
Coolant separator and coolant recovery for clean coolant-
free exhaust. Practically no coolant vapor with 1 mg/m3
of residual coolant, referred to ambient conditions.
Cylinder-integrated non return valve.
Direct coupling between cylinder and electric motor.
Soundproof cabin allows [68 dB(A)]
Fully automatic operation: automatic suction valve,
coolant temperature control, control switches, safety
vacuum gauge, main switch, all on board.
Control panel with vacuum gauge, coolant separator
cartridge pressure drop indicator, hour meter, active
circuits control warning light, manual security button and
key starter.
Very low maintenance cost thanks to design simplicity
and to few moving parts subject to wear.
Vertical layout for space economy.
CE certification is standard, others are available upon
request.
Air cooling also for hot climates (up to 55°C), water cooling is optional.
Air cooling through an aluminum cooler and a temperature controlled fan.
"Closed-loop" lubrication circuit ensures negligible coolant consumption.
Single-stage suction volumes at 50 Hz of 250 m3/h. 99,95% maximum vacuum degree (0,5 mbar residual absolute pressure) with performance curves constant up to 95%: the best achievable result by a single stage vacuum pump.
Special aluminum alloy vanes provide active sealing according to the traditional Pneumofore feature and guarantee a stable performance even after decades of operation, avoiding efficiency loss and minimizing cost of operation and maintenance. "Plug and play" pumps, easy to install and integrate. "H" version for vapour suction. Max quantity of water vapor suction is 17 kg/h at 50 Hz. Max pressure of water vapour suction is 120 mbar(a).
Operation with frequency converter possible with range from 35 to 60 Hz (as option).
