DrumDiaphragm Pumps
Air Operated Drum Diaphragm Pumps
ALUMINUM, STAINLESS STEEL SIS 2343, PP OCH PVDF
This type of pump is for the emptying of drums. Dominatordrum pumps series P is manufactured inSweden and equipped with our patented air valve system.With this unique air valve there is no risk that the valve willstall in the centricity, and cause production break-down.
There are two sizes available, ½” and 1” dischargeconnection. The suction pipe is equipped with a sliding 2”standard drum bung.
This pump range is suitable for the transfer of both non-corrosiveand corrosive liquids.
The discharge capacity is proportional to the stroking speed andcan be infinitely varied from 0-100 % by regulating the compressedair supply with a pressure regulator, or with a valve on thedischarge pipe (e.g. a pistol valve).
The pumps are self-priming, can be run dry, require no pressurerelief equipment and are suitable for continuous and intermittentduty.

| VALVEBALLS | Performance curves. For pumps type P3fitted with teflon diaphragms reduce water discharge figures by 15%. CAUTION: Do not exceed 10 bar air supply pressurefor metallic pumps. Do not exceed 5 bar air supply pressure for plastic pumps. We recommend the use of an air regulator on the airsupply. |
