Diaphragm Compressor/Vacuum Pump

Features

Gast Diaphragm Compressor / Vacuum Pumps

• They come with maintenance-free ball bearings for reduced frictional losses.
• These pumps feature a head assembly made of chemical / heat resistant PPS (Polyphenylene Sulfide) to resist corrosion on exposed surfaces.
• They can be mounted on any plane and have alternate stroke options.

Thomas Diaphragm Compressor / Vacuum Pumps

• They have enclosed housing and motor vents for increased heat dissipation.
• These compressor & vacuum pumps come with permanently lubricated bearings to reduce frictional losses.
• They feature a balanced pump design and thermal protectors for smooth and low-vibration operations.
• These pumps offer an automatic shut-off function for decreased overheating.
• They have die-cast aluminium construction for increased strength and corrosion resistance.
• These pumps are equipped with a diaphragm compressor for positive sealing and to prevent the entry of contaminants.

Working Mechanism

• During the intake stroke, the diaphragm moves downwards, which increases the chamber's volume and creates a vacuum inside it.
• Air or gas flows into the chamber through the inlet valve.
• During the compression stroke, the diaphragm moves upwards, decreasing the chamber's volume, compressing the air or gas inside and increasing its pressure.
• The outlet valve opens and the compressed air or gas flows out of the chamber.
• After the compression stroke, the diaphragm returns to its original position and the exhaust valve closes.
• The chamber's volume increases, creating a vacuum and the process repeats.
