The DDP and DDA pneumatic double diaphragm pumps are suitable for transferring different types of fluid such as oil, water, antifreeze, urea (AdBlue/AUS32) or by the suction of waste oil containing abrasive residues and solid parts.
The absence of sliding parts subject to wear keeps the pumping efficiency constant over time and allows to run dry without damage to the pump or the pneumatic system.
With a 1:1 compression ratio, they allow a large-volume transfer at a short-medium distance in a very short time.
The pneumatic exchange distributor with anti-stall features is made of high quality composite material to guarantee corrosion resistance and does not require lubrication.
The pumps are available with a Polypropilene or aluminium body and are fitted with high chemical compatibility and heat resistance diaphragm. They can be used in potentially explosive atmospheres (II Ex 3G/II 3D) in compliance with ATEX Directive 2014/34/UE.
