MATERIAL AND TEMPERATURE RANGE
Material Descripon Temperature Range
Stainless steel (SUS):
Stainless steel is a family of iron-based alloys that contain a minimum of approximately 11% chromium, a composion
that prevents the iron from rusng, as well as providing heat-resistant properes.
-196~800ﾟC
Aluminum alloys (AL):
Aluminum has a high chemical anity to oxygen, which is an oxide lm that can avoid oxidaon. It also has excellent
corrosion resistance, high electrical conducvity, and thermal conducvity, and is non-ammable and non-toxic.
-230~500ﾟC
Polypropylene (PP):
It is a thermoplasc polymer used in a wide variety of applicaons. It has good resistance to hit. Polypropylene at
room temperature is resistant to fats and almost all organic solvents. Non-oxidizing acids and bases can be stored in
containers made of PP. Polypropylene is used in the manufacture of loudspeaker drive units. It is a common polymer
material.
-5~100ﾟC
Thermoplasc
Urethane (TPU):
Thermoplasc polyurethane (TPU) is any of a class of polyurethane plascs with many properes, including elascity,
transparency, and resistance to oil, grease, and abrasion. Technically, they are thermoplasc elastomers consisng of
linear segmented block copolymers composed of hard and sosegments. It has many applicaons including arms,
medical, food industry.
-30~100ﾟC
Viton:
In terms of chemical resistance, uorinated rubber has excellent corrosion resistance. For organic solvents, inorganic
acids, strong oxidants, and greases are superior to other types of rubber.
-25~200ﾟC
Santoprene:
Santoprene thermoplasc vulcanizates (TPVs) are high-performance elastomers, which oer manufacturing exibility,
ease of processing, and durability. It combines the characteriscs of vulcanized rubber with the processing properes
of thermoplascs.
-40~135ﾟC
Polyethylene (PE):
The thermoplasc resin is made by polymerizaon of ethylene, which is also includes a polymer of ethylene and a
small amount of the polyethylene alpha in the industry. It has excellent electrical insulang properes, very low water
absorpon, and good low-temperature resistance.
-40~80ﾟC
Teon:
PTFE is used as a non-sck coang. Because of its extreme non-reacvity and high-temperature rang, PTFE is oen
used as the liner in hose assemblies, expansion joints, and in industrial pipelines, parcularly in applicaons using
acids, alkalis, or other chemicals. Its friconless qualies allow an improved ow of highly viscous liquids, and for
uses in applicaons such as brake hoses.
-190~260ﾟC
Bakelite:
The plasc is made from synthec components. Its properes made it suited for a much wider variety of purposes. It
was resistant to heat and would not conduct electricity, so it was a really good insulator—which made it parcularly
useful in the electrical industries emerging.
-50~150ﾟC
Ethylene Propylene
Rubber (EPDM):
EPM is considered a valuable elastomer due to its useful chemical and physical properes; it is resistant to heat,
oxidaon, ozone, and the weather and it is also not suscepble to color loss.
-40~138ﾟC
Nitrile Rubber (NBR):
It is a synthec rubber copolymer of acrylonitrile (ACN) and butadiene. NBR has good resistance to oils, ordinary
diluted acid, and alkali. The black NBR rubber (containing carbon black) has excellent anstac properes. But, when
it is aached to ultraviolet and ozone environments, it will be geng brile. (Disadvantages for outdoor working) It is
suitable for work and energy-intensive processing. (vulcanizaon, hardening)

IMPORTANT SAFETY INFORMATION

INSTALLATION CONSIDERATIONS
9
Installation and Assembly Considerations
◆ Connect the suction and discharge ports of the pump with a hose or flexible pipe to avoid damage caused by vibration of the pump. Never step on
the diaphragm pump or use other methods to apply weight to the pump body, or suspend the pump. Otherwise, there is a danger of personal injury
or equipment failure.
◆ The suction head of the inlet should be less than six meters (For water).
◆ The direction of the pipe (inlet and outlet) can be turned, but please pay attention to the O-ring when disassembling and installing it and locking
the pipe well to prevent leakage.
◆ We suggest that you can install the air filter, regulator, and lubricator (FRL) on the air inlet of the pump.
Adjustments for connection of high air pressure
◆ The air source of the air compressor is connected to the air inlet of the pump through the air pressure hose. It is operated by the air filters. The
supply air pressure used shall not exceed the maximum operating pressure.
◆ We suggest that you can install the air regulator on the air inlet of the pump. The supply air pressure used shall not exceed the maximum operating
pressure.
◆ Check the air filter at the air pressure input regularly to drain the accumulated wastewater and impurities. If too much wastewater is introduced
into the pump body, the wastewater and lubricating oil will emulsify and affect the lubrication of the parts, or block the pores, thereby affecting
the operation performance of the pump or causing malfunction.
Air Line Moisture
◆ Water in the compressed air supply can create problems such as icing or freezing of the exhaust air,
causing the pump to cycle erratically or stop operating. Water in the air supply can be reduced by using
a point-of-use air dryer to supplement the user’s air-drying equipment. This device removes water from
the compressed air supply and alleviates the icing or freezing problems.
Air cycle
◆ To start the pump, the air compressor provides air pressure to the body of the cylinder base of the pump,
flowing into the Sequential and Air Valve through the air hole. It drives the diaphragm and shaft doing power conversion.
During the conversion process, the deflated gas is discharged through the silencer. Please make sure that the exhaust gas
pipeline is smooth to avoid the blockage of the pump.
Liquid delivery process
◆ When the pump is used for materials that tend to settle out or solidify when not in motion, the pump should be flushed
after each use to prevent damage. (Product remaining in the pump between uses could dry out or settle out. This could
cause problems with the diaphragms and check valves at the restart.) In freezing temperatures, the pump must be
completely drained between uses in all cases.

FAQ
11
A. If your pump won't start.
a. Air inlet unusual: Check the air regulator whether works or not. If it can’t work, change the abnormal parts.
b. Pipeline clogging: Check the fluid pipe whether blocks or not. If it blocks, removing the obstruction. (Make sure the pipe is relieved air pressure to prevent casualty.)
c. Damaged parts: If the parts of the pump have damaged, please contact a professional person.
B. Air entrainment in the pipe
a. Loose joints: Check the input pipeline whether close tightly.
b. Diaphragm problem: The diaphragm loose or ruptured might lead air escape to the pipeline, please contact a professional person.
C. Fluid leaks from pump exhaust
a. Condensation: If it leaks oil-water mixture from the silencer, not the liquid which transports. It should enhance the air pressure pipeline and install the modular type F.R.L unit.
b. Diaphragm problem: If it is the liquid being transported, the diaphragm may be loose or ruptured. Please contact a professional person.
D. Pump flow rate dropping or it is irregular working.
a. Ball valve abnormal: If the ball valve has severe wear parts or include foreign objects, it might cause a ball valve abnormal. Please change the parts or remove the foreign object.
b. O-ring abnormal: If the O-ring wear and tear, it might lead to air pressure unbalanced. You can purchase spare seal kits by yourself to exchange the broken O-ring.
E. The pump works to slow down or stall easily.
a. Pipeline stuck: Make sure whether the inlet/outlet pipelines blocked or not. It might cause the inner pipeline to get smaller. We recommend you to clean up or change the pipeline.
b. Abnormal lubrication: Ensure the air chamber of the pump whether lubricates sufficient or not. Please clean up the dirty parts and relubrication. (It is recommended to add lubricating
oil to the air pressure inlet pipeline every half year, don’t exceed 10ml each time.)
c. Sequential valve abnormal: If the deterioration of the sequential, if it is worn, please change it.
d. Compressed Air Lines Freezing: The Slithery Mass Valve #53 might be frozen because of low temperature and condensate. If it happens, it is recommended to add antifreeze in the pipeline and enhance
the air-drying to improve the situation.
e. Clogged Silencer: If the air quality in the environment is horrendous, it may cause the air pressure source to mix dust. When it happens, it will block the silencer hole, which will cause unsatisfactory
exhaust after a while. It is suggested that replace the new or a larger aperture silencer.
F. Air leakage
a. The Slithery Mass Valve #53 and Include Ply #54 are worn: If the Slithery Mass Valve #53 and Include Ply #54 are worn. It will have occurred air leakage which will cause the pump to operate abnormally.
If it happens, please replace the part.
b. O-ring is worn: If the O-ring inside the Body of Sequential to Air Valve is worn. It will have occurred air leakage which will cause the pump to operate abnormally. Please replace the O-ring.
G. There is an abnormal leak at the pump junction
a. Air pressure is overload: Pump operating pressure cannot more than 8.3 bar (kg/cm^2). If it exceeds, it will cause the liquid leakage or damage of
the pump, it should adjust the air pressure range.
b. The joint is loosely sealed: Except incomplete locking, if the O-ring or Pad of the pump joint has deformation or wear, it will be loosely sealed and then leakage.
Please replace the parts of the pump.
S. If these answers cannot solve your problem, please contact DYI SHENG’s staff.
