Product Details

QBY Plastic Pneumatic Diaphragm PumpSince its launch, it has been adopted by more than a thousand domestic petroleum, chemical, electronic, ceramic, textile, paint, and pharmaceutical machinery system units. It is installed in various special occasions to pump media that cannot be pumped by conventional pumps, and is an ideal product to replace gear pumps, achieving satisfactory results.

QBY Plastic Pneumatic Diaphragm PumpUsage requirements

1. QBY plasticPneumatic diaphragm pumpThe vibration is extremely mild, and in general, bottom foot bolts are not required.
If dirt enters the compressed air, it will affect the normal start of the pump. It is recommended that users install pneumatic triple fittings.
When suctioning media that are prone to freezing, a valve should be installed at the inlet of the pump. When the pump is stopped, the valve should be closed first, and then the pump should be turned on for a few minutes until the medium in the pump body is completely drained to avoid difficulty in starting the pump again. When replacing the diaphragm, it is necessary to clean the wrist connecting rod and lead sleeve inside the pump, and do not damage the white PTFE sealing ring. Install it as it is and it can be used.

QBY Plastic Pneumatic Diaphragm PumpApplication examples

1. Cleaning the bottom of the oil tank, although there is a cushion method for oil pumping, cannot guarantee that the oil will be completely pumped out, and there will always be at least 3-5mm thick oil layer left on the surface. Taking a 5000m3 oil tank as an example, approximately 1-1.5t of oil is lost each time. For oil tanks with low-level dehydration tanks, although the remaining oil and water can be discharged to the oily wastewater treatment plant for recycling, the volatile oil products are mostly evaporated during transportation and pollute the environment.
2. During the process of oil refining production scheduling, temporary tank dumping, loading and unloading, and oil sampling are often required for oil products. Alternatively, in order to avoid contaminating normal pipelines, connecting temporary pipelines with a diaphragm pump can quickly and conveniently accomplish this task.
3. A 3000t oil tanker is unloaded using a fixed screw pump for bottom oil recovery. At least 50t of oil should remain between the warehouse partitions. If a larger displacement isolation pump is used, good results can be achieved.
4. The transportation of gas and hydrogen sulfide residue at the bottom of the refinery flare requires centralized discharge and treatment of gas residue and sulfur-containing water, otherwise it will form acidic corrosion equipment.
5. Ceramic industry: Use this pump to extract glaze slurry and can be used to supply pressure to a filter press.
6. During the maintenance of drainage well pipelines, valves, and underground ditches, it is necessary to remove waterlogging and dirty oil. Although using a submersible pump can completely drain the water, these places are often far away from the power source, which is very inconvenient. If a diaphragm pump is used, a compressed gas cylinder can be used as the power source to recover dirty oil and discharge water.
7. The cleaning of sewage treatment plants and sludge tanks. The sludge tanks in sewage treatment plants often accumulate a large amount of oil sludge and silt, which need to be cleaned. Diaphragm pumps are used for flexible suction, which is convenient, labor-saving, and time-saving.
8. The liquefied gas pump room and laboratory are used to drain waterlogging. Due to the low terrain and first level fire prevention zone, using diaphragm pumps to drain waterlogging is safer and much more efficient than using water or steam pumps.

In addition, QBY plastic pneumatic diaphragm pump has its own advantages in the application of cyclic acid refining and material transfer, loading and unloading of sodium sulfite liquid, and loading and unloading of benzene raw materials.
