Air consumption cut for AODD pumps

AxFlow now offers a new approach to reducing air consumption for larger size air-operated double diaphragm (AODD) pumps. Using the MizAir, it is said to be 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 will follow later in 2010. The microprocessor controlled MizAir consists of a high-flow normally open two-way valve and an electronic control unit. 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 the benefit of a reduction in the noise level of the exhaust air.

Low on power consumption, MizAir is an intelligent device and can continuously monitor the speed and other operating parameters of the pump and make adjustments to the valve timing as required.
