- Description
- Areas of use:
Depa pneumatic diaphragm pump type DH-TP/TPL has a pump housing of PTFE (type DH-TP) or conductive PTFE (DH-TPL). The centre part is made of PP or conductive PP. The pump has a simple, reliable and leak-proof design with integrated valve seats and integrated flange connection. Diaphragm, balls and valve seats of PTFE.
The pump has optimised flow characteristics and can handle particle size up to 12 mm and discharge pressure up to 7.0 bar.
The pump is designed to pump highly corrosive, difficult-to-handle liquids in, for example, the chemical, pharmaceutical, steel or paper industries.
The pump complies with the Machinery Directive 2006/42/EC and ATEX according to Directive 2014/34 EU:
II 2GD Ex h IIB T6...T4 GbDb, II 2GD Ex h IIC T6...T4 GbDb or I M2 Ex h IIB T6...T4 Mb.
