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.
