AxFlow reduces compressed air costs for AODD pumps
05 July 2010
AxFlow is now offering a novel approach to reducing air consumption for larger size air-operated double diaphragm (AODD) pumps. Using the MizAir, it is possible to reduce air consumption by up to 50% with minimal loss of fluid flow.
Designed for close-coupling to the pump, MizAir requires just a 24Vdc power supply. A self-powered ATEX version is to be introduced later in 2010. The microprocessor controlled MizAir consists of a high-flow, normally open, two-way valve and an electronic control unit. The valve and control unit operate to deliver precisely timed pulses of air to the pump at the start of each pump stroke. Because less air enters the pump there is less air to exhaust and this helps the pump to start its next cycle as there is less resistance to the return stroke. There is also major additional benefit of a reduction in the noise level of the exhaust air.
The MizAir is an intelligent device and is able to monitor continuously the speed and other operating parameters of the pump, as well as make adjustments to the valve timing, as required. The MizAir is low on power consumption and has a long life cycle.
