DIAPHRAGM METERING PUMP SERIES

SUMMARY
A hydraulic double-diaphragm metering pump adds an extra diaphragm to a hydraulic diaphragm metering pump, monitored by sensors or instruments, to prevent accidents caused by the rupture of a single diaphragm . It includes diaphragm rupture monitoring. The alarm system improves the safety of pump operation.
Maximum flow rate per head ≤21000 L/H Maximum pressure ≤ 70 MPa .
APPLICATION
metering and conveying media that are highly corrosive, volatile, flammable, explosive, highly toxic, malodorous, dense, viscous, radioactive, or valuable. Delivery. Widely used in chemical, oil and gas, environmental protection, power, pharmaceutical, mining, metallurgy, papermaking and other industries.
YUHAO SPECIAL ADVANTAGE
1. The pump has its own control system, monitoring sensors, and audible and visual alarms, which provide faster response time and higher safety, making it superior to local display instruments.
2. The patented integrated adjustable eccentric mechanism is highly efficient and reliable, with a stroke that can be steplessly adjusted from 0 to 100%. The metering pump's stability, repeatability, and linearity can all reach ±1%.
3. Single or multi-layer metal diaphragms can be used, with a maximum pressure of 70 MPa.
4. Diverse high-precision check valve assemblies (ball valve, stacked valve, angle valve, etc.), and the valve seat, a vulnerable part, can be used on both sides, reducing operating costs and improving maintenance efficiency.
FEATURES
● The hydraulic end is sealed with a double-layer diaphragm, which prevents leakage and enhances safety. During normal operation, the double-layer diaphragm is vacuum-bonded, ensuring high metering accuracy.
• If the diaphragm ruptures, the sensor can detect it within 0.2 seconds and send a feedback signal. The metering pump's built-in control system immediately stops the metering pump and issues an audible and visual alarm, effectively protecting the user's safety. Safety. Depending on user needs, relevant signals can also be sent to the central control room for immediate alarm and repair.
● PTFE membranes are typically used , as they have excellent corrosion resistance and temperature resistance.
● The pump has a built-in overload valve for automatic pressure relief and protection, but it should not be used for extended periods.
● It has a wide range of flow/pressure applications and can be used in special media such as high and low temperatures, high viscosity, corrosiveness, solid content, flammability, explosiveness, toxicity, malodor, and radioactivity.
● It can be connected in parallel with two or more heads to increase flow rate and reduce pulse. It can also transport multiple media at the same time for proportional use.



● An optional high-efficiency metering pump stroke controller can be added to achieve a wider range of automated
