The series of Verderair double diaphragm pumps are highly engineered diaphragm pumps, delivering a smooth, reliable flow for all circumstances. The new air valves design guarantees a perfect, non-stalling operation, even at low pressure. The air valves do not need any lubrication. Thanks to their unique design, the pumps are able to handle very abrasive and/or viscous products.
