The characteristics of pneumatic diaphragm pump are very obvious. Compared with other pump transportation equipment, SANDPIPER pneumatic diaphragm pump does not need motor drive, but uses high-pressure air as the power source, which not only avoids the dangers of short circuit and power failure of conventional electric pumps, but also is more portable. At the same time, there is no overheating and crash, and long-term idling will not damage the pump body, The adaptability to various process media is also excellent.

Advantages of pneumatic double diaphragm pump:

1. Common externally maintainable gas distribution system

The unique externally repairable gas distribution system (ESADS+PLUS) of Subway pneumatic diaphragm pump can be used to repair and protect the pilot valve and main gas valve online in five minutes by removing four bolts with one wrench. There is no need to remove the pipeline, let alone the pump. Then, it can ensure minimal maintenance time and significantly save operating costs.

2. Suitable for processing multiple media

It can handle materials containing large particles, such as mud, abrasive, corrosive or easily deposited particles.

Variable flow self conditioning, standard metal pump shut down pressure to 8.6 kg

With proper selection, one pump can transport multiple media without considering the motor power. 3. Durable

Transport particles containing large particles (even close to the pipe orifice)

Shear sensitive medium

It can work dry and shut down immediately under the condition of dead point, without damaging the pump risk

No damage to shear sensitive medium

Strengthen shaft design 4. Economical use and convenient protection
