Polytetrafluoroethylene | 39 to 500°F 4 to 260°C | 40-60psi | • Extremely chemically resistant — often used with heptane and methyl chloride • Extremely steam resistant • Not really an elastomer; has cold flow issues that can result in leaking • Relatively higher cost compared to other materials • Currently only available for the following ASEPCO tank valves: Tank-Bottom, Tangential, Sterillite, Sample, Retrofit, Zero Dead Leg, Point of Use, Process, and Divert valves | |
Diaphragms Pump WORKING PRINCIPLE
The hydraulically actuated diaphragm metering dosing pump liquid end has a Teflon diaphragm which acts as a barrier between the piston and the process fluid. The piston's pumping motion is applied to hydraulic fluid which causes the diaphragm to flex back and forth as the piston reciprocates.
The hydraulic diaphragm metering pump operates with equal pressure between the hydraulic and process fluids. This eliminates diaphragm stress, since the pressure is essentially equal on both sides at all times. Two contour plates encase the diaphragm to contain its travel. The hydraulic and process fluids pass through carefully engineered holes in the contour plates in order to come into contact with the diaphragm, Relief and refill valves control the volume of hydraulic fluid. An automatic air bleed valve continuously purges air from the hydraulic fluid.
Diaphragm Pump STRUCTURE AND MATERIAL
1. Pump head: SS304, SS16, PVC, PTFE.
2. Metering valve: SS304, SS316.
3. Ball valve: Silicon dioxide,SS304,SS316,Ceramic.
4. Diaphragm: Quality PTFE.
5. Motor: 50Hz/ or 60HZ, explosion-proof type available.
Diaphragm pump OPITIonAL MANUFACTURING
1. Double diaphragm and alarm system:Suitable for delivering viscous, poisonous, corrosive liquid, if one diaphragm broke, pump will stop and send out an alarm.
2. Remote control system:Outside 4-20mA signal can be inputted into pump to control the pump operation.
3. PTFE lined pump head material:If the handing liquid has strong corrosion again stainless steel, a PTFE lined pump is a good replacement. All the pump wet part will be lined with the PTFE material.
Diaphragm APPLICATION
The hydraulic diaphragm metering pump is sealed. It therefore is an excellent choice for hazardous, toxic, or corrosive chemicals. For extra protection, double diaphragm and leak detection modifications are available, although they are considered redundant since this design is extremely durable.
Because the process fluid must pass through relatively small holes in the contour plate, the disc diaphragm liquid end is not the best choice for slurries, and they are also usually not the best choice when pumping viscous fluids.
Industry area: such as waste water treatment, environment protection, petroleum and natural gas, chemical industry, metallurgy and mines, pharmacy and medication, power plant, paper making, food industry, printing and dyeing, laboratory, nuclear power and military industry.
