High Speed Stainless Diaphragm Pump / Silent Food Grade Diaphragm
Pump
Stainless Diaphragm Pump Introduction
The diaphragm pump offers high volume delivery even at low air
pressure and a b road range of material compatibility options
available.Refer to the model and option chart.The pump is provided
with the modularized air motor and fluid section.
The air operated diaphragm pump alternately generates the intake
fluid pressure and positive fluid pressure in the fluid chamber by
using the pressure difference in the air chamber. The ball valve
can ensure the forward flow of fluid.
Pump cycling will begin as air pressure is applied and it will
continue to pump and keep up with the demand. It will build and
maintain line pres -sure and will stop cycling once maximum line
pressure is reached (dis -pensing device closed) and will resume
pumping as Needed

Stainless Diaphragm Pump Application and Advantage:
Pneumatic diaphragm pumps are operated with compressed air .
diaphragm pumps is suitable for pumping fluids with particles, and
various liquids, which are highly viscous, volatile, corrosive or
toxic, as well as colloids. The pump body is made of aluminum
alloys, cast iron or stainless steel. The diaphragm is made of high
quality rubber such as Nitrile rubber, chloronorgutta rubber,
fluoroine rubber. The diaphragm pumps are widely used in the
petroleum chemical, electronic, ceramic, food and textile
industries.
Remark: The pumps weight in the table are approximation.. Will be
caused differences because of the components. Just for reference.

Stainless Diaphragm Pump MAINTENANCE
- Refer to the part views in the assembly chart for the parts’ number
and name to understand the information of the part and service
kits.
- Parts which marked with “Vulnerable parts”, to prepare these parts
in hand will help you save time for fast maintenance and reduce
downtime.
- Maintenance service kits’ functions are separated into 2
independent sections: 1, Air kits; 2, Wet kits. Wet kits will be
further subdivided to match the material options for typical parts.
- Provide a clean work surface to protect sensitive internal moving
parts from contamination from dirt and foreign matter during
service disassembly and reassembly.
- Keep good records of service activity and include pump in
preventive maintenance program.
- Before disassembling, empty captured material in the outlet
manifold by turning the pump upside down to drain material from the
pump
Troubleshooting guidance
1.Air outlet has fluid when pumping
Check if the diaphragm be damaged
Check if the diaphragm bolts loosening
2.The output fluid has bubble
Check the suction pipe joints are well sealed
Check the suction pipe and fluid inlet are well sealed
Check the ring between fluid inlet and fluid cap are with O-ring
Check the diaphragm bolts are fastened
3.Pumping capacity is low
Check if the air supply is stable
Check whether the inlet and outlet is blocked
Check the joint to the fluid inlet is sealed and not leakage
Check if the ball stick to the ball seat or ball seat is not
suitable
4. Without reciprocating motion, the air flow is discharged from
the exhaust port
Check the sealed ring of the main air valve
Check the sealed ring of the pilot rod valve
Check the sealed ring of the diaphragm rod
