SDMP301 is equivalent to the "SDMP205" follow-up model released in October 2004, and adopts the same internal structure as "SDMP305" released in August 2005. By mechanically oscillating the diaphragm designed inside the pump, a volume change is formed to transport the liquid and the gas.
The product measures 25 x 25 x 4.8 mm and weighs about 4 g, basically the same as the SDMP305. The intended use is to supply fuel to small fuel cells equipped with laptops and PDAs.
We offer riser cover for the straight one, necking downs and oblique riser. It is convenient for you to choose open riser or closed one. It has low density, high strength and good toughness, which suit for all kinds of black and non-ferrous casting. It can be set on the plate shape or embedded sand mold after modeling.
Heating mechanism: The exothermic Insulation Riser head has adopted good insulation material and high efficient exothermic. There are little quenching effect, once the liquid steel was pour into the riser head, the exothermic reaction will be activated, then the riser head will heat the liquid steel with it`s fever. After the reaction, the insulation material will ensure the coagulation time of the liquid steel. The best feeding efficient comes from the characters: Initial adiabatic, then fever, heat preservation for a long time in the end.
