INSTALLATION CONSIDERATIONS

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.
