Busch R 5 RD vacuum pumps for food packaging

Busch Vacuum Pumps’ R 5 RD vacuum pumps require 20% less motor power than comparable models, according to the company.

Designed for the vacuum packaging of foodstuffs, the pumps can be easily cleaned because the surfaces are smooth, the oil lines are only on the inside and the housing has no cooling fins. Maintenance has been reduced as all of the maintenance elements are attached to an operating side, and only one single air/oil separator must be changed.

An oil/water heat exchanger on the rotary vane vacuum pump can reduce waste heat and thus reduce the energy costs for air conditioning. Furthermore, the heat exchanger can be used to generate warm water, which can in turn be used as warm water during operation. The vacuum pumps can be retrofitted with heat exchangers.

Packaging processes can be designed more economically through the use of intelligent technologies for the vacuum supply — from an optimised control system, to frequency control, to the use of a vacuum container.

Centralised vacuum systems are suitable for companies that package foodstuffs on several thermoforming packaging machines, tray sealers or chamber machines. Centralisation can reduce energy costs by 50% or more because fewer vacuum pumps are required. Performance control can also be adjusted to fit the requirements of overall operations. Safety is enhanced because if a vacuum pump fails or needs maintenance work, full vacuum power remains intact.
