1, Material (take Aluminum alloy for instance): Inner and outer layers of Aluminum alloy has been special treated.
Advantages: beautiful appearance, smooth, abrasion, corrosion resistance, 10 times stronger than pure Aluminum.
2, Upper manifold with 3 inlet and outlet in the middle and both side.
Advantages:After middle inlet & outlet blocked, one pump can be divided into two, greatly decrease cost.
3, Ball room: circular arc shape, smooth surface.
Advantages: Smooth arc-shaped room, not easy to abrase ball seat, protect ball seat, increase working life.
4, Cover: smooth arc, less blind corner, more coincide with principle of hydromechanics.
Advantages: more reasonable design, enlarge diaphragm's working life, raise flow and head at the same working conditions.
5, Diaphragm: available with variety material, more flexible, not easy deformed, automatic return to original position.
Advantages: diaphragm's design are more flexible, increase working life, more than at least 5 times movement compared with regular diaphragm.
6, Clapboard: arc-shaped design, have the same shape with diaphragm,completely match diaphragm, and protect diaphragm; with additional6 air-guide hole, more coincide with principle of aerobiology and hydromechanics, increase diaphragm working life.
Advantages: Protect diaphragm, Enlarge working life.
7, Central Axis: By hardening treatment on the axis, only have 2 V-ring sealed, can interchange V-ring with air motor. only 2pcs V-ring is ok to install into hardening treated axis, these V-ring also interchange with air motor's V-ing
Advantages: Easily disconnect and reassemble , not easy to damage, V-ring cyclic utilization, save the cost of maintenance.
Pump Axis is smooth round, not easily damaged, have long working life.
8, Central body: If it breakdown, replace two gasket V-ring it ok.
Advantages: Easily repairing, save maintenance cost.
9, Air motor: pilot type, move vertically and horizontally, after a long time abrasion, there can be automatic compensation.
Easy-wear part adopt special unitary polymer, hardness and flexibility are better than metal, easily to start operate at 0.5kg air pressure
Advantages: never stop operating
less spare part
lubricate automatically, no need lubricant
working in terrible environment
10, Ball seat: both sides can be well used.
Advantage: use repeatedly and save cost.
11, Low noise
Advantages: improve work environment.
12, Center body sealed gasket: can be used repeatedly, convenient dismantlement and installment.
Advantages: Convenient maintenance.
13, pneumatic diaphragm pump realize long working life, strong and durable, cost-effective. Air motor 15 years warranty, Pump body 5 years
14, Pioneered the highest head record of diaphragm pump history: The highest head can be up to more than 20m.
15, Pioneer for Full PTFE pump. ( Special pump for nuclear power station)
