Marathon is the brand of WARREN RUPP manufacturer. It IS THE FIRST PROFESSIONAL DIAPHRAGM pump manufacturer to obtain ISO9000 QUALITY certificate in the world, and the pioneer position in the world market of pneumatic double diaphragm. Pneumatic diaphragm pump is widely used in petrochemical industry, water treatment, food industry, machinery manufacturing, shipbuilding, pharmaceutical, paint and other fields. Its characteristics are completely self-priming, no seal, dry turn variable flow and head, optional export, no motor and explosion-proof, can handle wear objects and high viscosity substances. Fully self-priming, flow adjustable, NON-destructive dry turn, a variety of outlet connection, bypass and return valve free, explosion-proof safety, no dead point guarantee.

The MARATHON MARATHON pneumatic diaphragm pump, the design is simple, numerous features, superior performance, no seal design, without motor, the pneumatic and seal design, without a motor, not leak, not pollute the environment, transport viscous medium, can transport high viscosity or medium containing particles, from water to almost every media such as tomato ketchup, self-priming completely, MARATHON pump can be switched from dry to self-priming under conventional conditions, with adjustable flow rate. Only by controlling the air source, the flow rate of the pump can be arbitrarily changed from zero to the maximum value, without damage during dry rotation. Compared with conventional pumps, MARATHON MARATHON pump will not damage under any idling condition. When the outlet pressure and driving pressure balance, pump will automatically stop the operation, so, just put export closed, the pump will stop operation, no longer need to install expensive bypass system, safety explosion-proof, air powered, won't produce sparks, the MARATHON MARATHON pump can be used in explosion-proof environment, no dead point, after years of practice and improvement, WARREN RUPP guarantees that all MARATHON MARATHON pneumatic double diaphragm pumps will not start poorly.

Advantages of MARATHON diaphragm pump:

1.ESADSPLUS oil-free lubrication, 100% non-crash.

2. Unique patented design of air valve (external maintenance type air valve system) is carried out from outside the pump body to reduce downtime and improve efficiency.

3. Patented air valve design, to ensure the minimum gas consumption, compressed air leakage is very low. There is no such thing as other brands of pneumatic diaphragm pump has a poor start and air valve icing pause phenomenon.

4. Excellent overall tightness, marathon pneumatic diaphragm pump all types of pneumatic diaphragm pump liquid parts fastening design are connected by bolts and nuts, to ensure no leakage for a long time operation.

5. MARATHON diaphragm pump has passed ISO9001 quality system certification, ISO4001 environmental management system certification and EC CE certification.
