A-30 Pneumatic Double Diaphragm Pump

Placed in Dongguan(China), ours is an emerging company serving the clients with broad range of products. This is due to our modern logistic facilities that we are able to meet the delivery deadlines with ease. The cutting edge A-30 Pneumatic Double Diaphragm Pump we offer has a tota weight of 3.5Kg.

Features

• A-30 diaphragm pump doesn’t spark.A-30 is not in need of electric power to drive and prevents from electrostatic spark after grounding

• Not overheating - The compressed air powers the pump. When exhausting gas out, it inflates and absorbs heat, so temperature reduces and noxious gas is exhausted out when the pump works

• Suitable for liquids with particle - As it works by positive displacement type and there is a inlet ball valve, it is unblocked easily

• Hard to cut materials - When the pump works, materials are sucked in the same way to exhaust them out, so they are cut easily. A-30 is suitable for pumping unstable materials

• Fluid flow is adjustable - A throttle is set in the fluid outlet to control fluid flow

• The diaphragm pump has a function of self-absorption
• Working without fluid or materials is not hazardous
• Suitable for a wide range of fluid, such as high-viscosity fluid, corrosive fluid and so on
• There are not complex control systems, cables and fuses
• The pump is small, lightweight and easy to move
• Without lubrication, it is easy to maintain and it won’t pollute the working environment as fluids drop
• 100% utilization of energy
• When the outlet is closed, the pump stops automatically. Equipment moves, wears out, gets overloaded and emits heat
• The pump keeps working efficiently all the time and won’t lower its performance because of abrasion
• Without motive seals in the pump, it is easy to maintain to avoid leaks

Working principle

• The double diaphragm pump is driven by compressed air, nitrogen gas and natural gas. The main directional pneumatic control valve distributes compressed air to the gas cavity and uniformly pressures the inner surface of the diaphragm. At the same time, gas is exhausted out via the guide outlet of air valve components from the rear of the other side of the pump. The pressure in gas cavity exceeds the pressure in fluid cavity, so that the connecting rod moves backwards and forwards, resulting in sucking from one side and exhausting out from the other side
• The direction of exhausting out and sucking fluids is in the charge of the direction of the check valve (ball valve or flap valve). Intake stroke makes the pump suck. Intake stroke reduces the pressure of cavities and increases their volumes, which results in pressure difference driving fluids to pass through the suction tube and suction check valve and flow into the outer fluid cavity
• Intake stroke drives the pump to move reciprocally (motion, stroke and circulation). The pneumatic double diaphragm pulled by the stroke machine sucks the moving diaphragm. The inner board the diaphragm pump touches the aligned driving piston, and then the movement is delivered to the center of the valve. After being activated, the guide valve shows a signal of pressure to the other side of the main directional control valve, and then the diaphragm pump changes the direction of compressed air to the other side of inner cavities
• In this way, the diaphragm pump works repeatedly, so fluids or materials are conveyed continually
