DEPA Diaphragm Pumps

DEPA peristaltic pumps are equipped as a standard with a patented vacuum system. It leads to many economic and technical advantages such as:

  • Very good suction properties up to 9.5 m / 31 feet lift (no additional suction equipment required.
  • Constant pump capacity during the entire hose life.
  • Enables the hose to reform to its full cross section.
  • Low reduction in capacity when handling viscous media.
  • Use as early warning system for a just in time hose exchange.


A diaphragm pump is a positive displacement pump that uses a combination of the reciprocating action of a rubber, thermoplastic or teflon diaphragm and suitable non-return check valves to pump a fluid.

DEPA® Air Operated Diaphragm Pumps have earned a reputation for enabling high quality positive displacement solutions in diverse industries.

Every day these pumps prove their reliability and efficiency all over the world in challenging operations and under the toughest application conditions.

Through the years this range of air operated diaphragm pumps has been continually updated and improved through intensive research, development and the use of new materials.

These products are manufactured to meet or exceed the quality demands of all industries we serve, with due regard for “aftermarket” requirements such as ease of operation and ease/cost of maintenance.

DEPA® Air Operated Diaphragm Pumps

DEPA® Air Operated Diaphragm Pumps is one of the world’s leading brands of superior quality, positive displacement pumps.

They provide reliability, efficiency and transfer control for all liquid and sheer sensitive materials, can handle viscous and abrasive products and often work in the toughest conditions and most demanding applications.

DEPA pumps are self-priming, and can run dry without damage.

They are the only AOD pumps with ATEX zone 0 compliant certification worldwide.

Being designed in a modular version, DEPA pumps ensure that both number of individual parts and stock keeping is kept at a minimum. This results in short down time and low maintenance costs. Besides, the modular design allows flexibility for the pumps to be used in other applications.
