Miniature Diaphragm Pumps for Liquid
Liquid diaphragm pumps are used where the requirements determine the need for a totally sealed system and the ability to self-prime. A Boxer liquid diaphragm pump additionally has the ability to transfer liquid, air or a mixture of both. The technology is suited to systems requiring both vacuum to 8m suction height and pressures to approximately 3 bar. The smallest Boxer liquid diaphragm pump is the 16K with an open flow of 150ml/m. These pumps are targeted at applications such as industrial ink jet printing or chemical analyser systems. Fine flow control via motor speed as well as brushless commutation are often specified for such applications. Moving through the range applications extend to liquid dispensing and waste liquid transfer in larger analytical applications. The 3MQ with a flow of 3.5 l/m is the largest liquid diaphragm pump in the Boxer range. Liquid pumps are built on platforms often additionally utilised as a gas diaphragm pump. With differing requirements characteristics such as speed, stroke, valves, elastomer choice and pulsation chambers are adapted to exactly match the media. To complement the full range of liquid pumps Boxer additionally offers a full range of peristaltic pumps.
