Pompe / A membrana

Pompe a diaframma per il trasferimento di liquidi abrasivi o con solidi in sospensione.

Pumps produced from metals often lack the required chemical resistance to corrosive media.

To meet such corrosive resistance requirements, we developed air operated pumps made from Polypropylene, PVDF or PTFE. 

Our non metallic pumps deliver the performance of metal pumps, and can be installed in chemically aggressive environments.

Virtually all fluids, from water to slurries/pastes can be pumped.

Various materials for body, diaphragms, valve seats and valve balls are available so that the pumps can be individually adapted.

Allow a variety of applications in sterile processes, especially in the pharmaceutical and health care industries. The materials used conform to 3A and FDA guidelines.

• Type DL-SF Cast stainless steel 316L electro polished
• Type DL-SL Stainless steel 304 polished
• Type DL-SU Stainless steel 316L polished

These pumps excel in various applications in sterile processes, especially in the pharmaceutical and health care industries. The materials used conform to FDA guidelines. These versions are certified by EHEDG (European Hygienic Equipment Design Group). The design of the DH versions conforms to the 3A regulations, and is certified thereunder.

DEPA Air-Operated High Pressure Diaphragm Pumps (series-M), type DB, are preferred by filter press operators.

The variable pressures possible with the DEPA pumps protect the filter press while the short filling cycles improve the productivity of the entire filter process.

The largest Air-Operated Diaphragm Pump in the world (DP 125) with a flow rate of up to 2400 kg (5291 lb/h) at a bulk weight of 60 g (0.1 lb)/l, was developed and manufactured by Crane in cooperation with process industry partners.

Until now, no other pump type has been able to fulfil the specific task settings of the industry in an economical and functional way.

All DEPA diaphragm powder pumps are fitted with specially formed suction and discharge manifolds for favorable flow conditions.

The high flow rate is achieved by good fluidization of the products. Regarding the discharge of granulates and crystalline media, special requirements have to be met.

Various materials for body, diaphragms, valve seats and valve balls are available.

Ideal for simultaneous and independent transfer of two media in one pump. Due to the special design of the suction and discharge connections the transferred media do not mix.
