Keller diaphragm pump from Germany, with strong corrosion resistance, directly purchased by Xieke

Keller Diaphragm pump is from Germany WILHELM KELLER GmbH & CO. KGThe pump products produced by the company. The company1933 Founded in, it is a family business with a long history.

DMP-15/25ATTIt is a pneumatic double diaphragm pump. The shell is made of aluminum, and the diaphragm is made of TFM/PTFEThe valve ball is PTFEtexture of material. Its maximum flow is 25L/minThe maximum working pressure can reach 8bar, possessing ATEXCertified to operate safely in hazardous areas.

Working Principle:KellerDiaphragm pumps belong to positive displacement pumps, which use the reciprocating motion of elastic diaphragms to transport liquids or gases. The diaphragm divides the pump chamber into two compartments, one side containing liquid or gas and the other side containing the driving medium. The movement of the diaphragm changes the volume of the pump chamber, thereby producing suction and discharge effects.

Product Features:Strong corrosion resistance: Some models, such as DMP-15/25ATTThe diaphragm and valve ball are made of TFM/PTFEand PTFEWaiting for advanced materials,PKThe series adopts a fully plastic pump casing, which can resist corrosive media such as acids, alkalis, and solvents.

Explosion proof safety: Many models have ATEXCertification, such as DMP-15/25ATTand PKThe conductive version of the series can operate safely in hazardous areas with explosive gases or dust.

Keller diaphragm pumps, with their corrosion resistance, explosion-proof, and leak free characteristics, are mainly used in the following scenarios: chemical and pharmaceutical industries: transporting various corrosive or high-purity media such as acids, alkalis, solvents, and chemical solutions, such as electroplating solutions, etching solutions, acid-base solutions, pharmaceutical raw materials and preparations. Some models have passed ATEX certification and can be used in hazardous areas. -Semiconductor/Photovoltaic: Transporting high-purity chemicals, photoresist, cleaning solutions, etc., requiring no leakage or pollution. The PK series full plastic pump casing and PTFE diaphragm can meet the high cleanliness requirements. -Environmental Protection and Wastewater Treatment: Treatment of solid corrosive waste liquids, sludge, etc. It is wear-resistant and has strong self-priming ability, and can be used for sewage lifting, sludge transportation, and acid-base neutralization systems. -Dangerous places and explosion-proof conditions: Models with ATEX certification (such as DMP-15/25ATT, PK conductive type) can operate safely in areas with explosive gases or dust, such as chemical workshops, tank areas, etc.
