Description
This pneumatic double diaphragm pump is suitable for use with fluids of higher viscosity or those containing solid particles (up to 3.5 mm in size). The unit is self-priming (up to 5 meters suction lift), operates without any electrical power supply, and can run dry without damaging the pump. Thanks to its robust construction, it is particularly well-suited for industrial and hazardous environments, and it complies with ATEX Directive 2014/34/EU – Zone 2.
The pump housing is made of aluminum, the diaphragms are composed of Hytrel® and PTFE, the check valve balls are PTFE, the seals are made of Viton®, and the valve seats are also aluminum. This material combination ensures excellent chemical resistance, durability, and reliable performance under demanding conditions.
The pump can be wall-mounted using a dedicated bracket (Article 7818), designed specifically for this model.
