Model: JBB series mechanical diaphragm metering pump

Flow range: 15-130L/H

Maximum pressure: 1.0Mpa

Membrane material: PTFE (overcurrent end face)

Pump head material: PVC、PVDF（PTFE）、 304, 316 (options: duplex steel, Alloy C-276, 904, titanium, zirconium, etc.)

Motor: 380V, 3PH, 50HZ (options: 110-480V, single-phase, 60HZ, variable frequency/explosion-proof/explosion-proof variable frequency, etc.)

Technical characteristics of mechanical diaphragm metering pump

• No dynamic seal, no leakage. Due to the static sealing of the hydraulic end diaphragm replacing the dynamic sealing of the piston, it is possible to achieve absolute no leakage when conveying the medium.

• In addition to clean water, it is more suitable for transporting flammable, explosive, highly toxic, odorous, and radioactive media.

• Structurally simpler than hydraulic diaphragm pumps, but more complex than plunger pumps.

• Can be equipped with a digital controller for metering pumps, achieving digitization and local and remote control.

• The diaphragm is made of a five layer composite structure pressed together (the first layer is a super tough acid resistant film, the second layer is elastic rubber, the third layer supports the iron core, the fourth layer is reinforced nylon fiber cloth, and the fifth layer is fully covered with elastic rubber), which can effectively improve the service life of the diaphragm.

• Add a stainless steel reinforcement plate design behind the diaphragm to improve its service life.

• The export pressure is generally below 1.0MPa, and the flow rate has a wide range of applicability. The measurement accuracy is lower than that of plunger pumps and hydraulic diaphragm pumps. When the pressure increases from small to large, the flow rate can change by up to 10%.

• Mechanical dual diaphragm design with diaphragm alarm detection can be selected.

Advantages of LiGao Mechanical Diaphragm Pump

diaphragm

The material of the overcurrent end is PTFE, which meets the requirements of corrosiveness.

The membrane is a five layer composite structure, which can effectively improve the service life of the membrane.

Transmission components

Turbine: Alloy copper, high cost, its wear resistance is 4.5 times that of ordinary copper material.

Worm: made of alloy steel and heat-treated, with high hardness, good wear resistance, and long service life.

Manufacturing: The main transmission components are processed by precision hobbing machines and worm gear grinding, and automatically inspected by CNC gear inspection centers, with high transmission efficiency and low noise.
