TCD-Pneumatic Diaphragm Pump
Newly upgraded third-generation pneumatic diaphragm pump:
Innovative toad ring tight air valve structure
• Longgong pneumatic pump development is based on a large number of experience in the existing pump type on top of the accumulation of a large number of new technologies, to meet the market demand for the advantages.
启航彩• The innovative Longgong ring tight gas valve structure has improved the safety and stability of the pump· ，more power, lower air consumption;
启航彩• Missed the pleasant sound of the tractor;
启航彩• Maintenance- and lubrication-free air control system, no dead spots;
• Can self-prime and support the transportation of solid particles;
启航彩• No monitoring required, long service life;
• An important factor in the structure is a solid design. Only a sufficiently solid pump body design can provide the necessary quality for reciprocation.
