RD manual diaphragm pump series
Principle of for Iow head, small flow pumping operations, by the pump body, radiators, and out of the water valve, diaphragm and push-pull rod.
Pump body can consist of one or two pump cavity. With two pump chamber diaphragm purmps, the diaphragm is set in the center of the purmp,or two diaphragm respectively in separated two pump cavity outside. Work by two people with hand manipulation and diaphragm connected to push the lever, promote the diaphragm for pressure into and spread of reciprocating motion, so that the two purmp cavity volume alternating enlarge and reduce. When expanded, the pump chamber pressure inlet valve outlet valve closes, water from pipes into the pump Chamber; when pump out pressure increases, the water inlet valve closed valv pump cavity drainage of water from the two pump water and drainage cavity alternating, per hour for pumping water10-.-20m3/h.
