DEPA · AIR OPERATED DIAPHRAGM PUMPS
DEPA Type DF Drum Air Operated Diaphragm Pumps – Direct Drum Mount AODP
DEPA Type DF drum AODPs mount directly onto 200-litre drums. Aluminium and SS316L, 1" port, for chemical and industrial drum emptying. Available at PC

Overview
The DEPA Type DF is a compact Air Operated Diaphragm Pump designed specifically for direct mounting on standard 200-litre drums and intermediate bulk containers (IBCs). The pump attaches via a standard drum adapter to the drum's bung opening, eliminating the need for a separate suction hose and reducing spillage risk during connection and disconnection.
The Type DF draws media directly from the drum with a built-in dip tube that reaches the drum base, allowing near-complete emptying without tilting or repositioning. Its compact dimensions and light weight make it easy to move between drums, and the compressed air drive means no electrical supply is needed at the drum location.
Available in aluminium and stainless steel 316L, the Type DF handles a wide range of chemical, lubricant, and industrial media. Polypropylene versions are available on request for corrosive or aggressive drum contents.
