Mechanical diaphragm pumps with reliable quality. GB types is robust and reliable motor driven metering diaphragm pumps. The stroke length can be adjusted to alter capacity of this pump. Two no-return valves prevent the feeding chemical form fowing back during pumping. Each pump with the reinforced plate is to pretect the diaphragm.
Model number: GB series mechanical diaphragm metering pump
Flow range: 240—1800L/H
Maximum pressure: 1.0Mpa
Diaphragm material: PTFE (flow end face)
Pump head material: PVC, PVDF (PTFE), 304, 316 (options: duplex steel, Alloy C-276, 904, titanium, zirconium, etc.)
Motor: 380V, 3PH, 50HZ (option: 110-480V, single-phase, 60HZ, frequency conversion/explosion-proof/explosion-proof frequency conversion, etc.)
1. Sealed, no leakage. Because the static seal of the diaphragm at the hydraulic end replaces the dynamic seal of the piston, it can never leak when conveying the medium.
2. In addition to clean water, it is more suitable for transporting flammable, explosive, highly toxic, foul-smelling, and radioactive media.
3. The structure is simpler than hydraulic diaphragm pumps, but more complex than plunger pumps.
4. It can be equipped with a metering pump digital controller to realize digitalization and realize local and remote control.
5. The diaphragm is pressed by a five-layer composite structure (the first layer of super tough acid-resistant film, the second layer of elastic rubber, the third layer of supporting iron core, the fourth layer of reinforced nylon fiber cloth, the fifth layer of elastic rubber is completely covered), Effectively improve the service life of the diaphragm.
6. A stainless steel reinforcement plate design is added behind the diaphragm to increase the service life of the diaphragm.
7. The outlet pressure is generally below 1.0MPa, and the flow rate is applicable to a large range. The metering accuracy is lower than that of plunger pumps and hydraulic diaphragm pumps. When the pressure changes from small to large, the flow rate can change up to 10%.
8. Optional mechanical double diaphragm design with diaphragm alarm detection.
1. The material of the overflow end is PTFE, which meets the corrosive requirements.
2. The diaphragm is a five-layer composite structure, which can effectively increase the service life of the diaphragm.
Turbine: alloy copper, high cost, its wear resistance is 4.5 times that of ordinary copper.
Worm: alloy steel, and heat treatment, high hardness, good wear resistance and long service life.
Manufacturing: The main transmission components are processed by precision gear hobbing machine, worm grinding, and automatically detected by CNC gear inspection center, with high transmission efficiency and low noise
