NUODEAN High Pressure Diaphragm Pump Manufacturer offers 2:1 ratio pumps designed for applications where 120 PSI maximum pump operating pressure is insufficient to overcome system requirements.
The flow rate is almost the same of the equivalent size pump output, though a maximum discharge pressure of 200 PSI can be achieved with only 100 PSI air inlet pressure supplied.
The 2:1 discharge ratio is achieved by applying air pressure to the surface area of both diaphragms, doubling the discharge output.
And The 2:1 High Pressure Diaphragm Pumps have certainly all the advantages of NUODEAN’s DP11 Series. See the following:
1. Stall-free Design.
2. Self-lubricating,lube-free and maintenance-free air system.
3. More flow and less pulsation:
Pilot air-distribution valve provides an positive,reliable,faster shift signal that avoids stall-out,and provides faster pump trip-over with more flow and less pulsation.
4. The use of dual ceramic dynamic seals:
More wear-resisting and to prevent & discharge pollution;Applicable to the harsh environment of air source;Long lifetime.
5. Large Flow Rate:
Faster pump reversing increases flow to a certain extent.
6. Anti-icing design:
With built-in vacuum pump chamber,it is anti-icing and effectively reduces the discharge air pressure and noise from work;Cold exhaust air is diverted from ice-prone components.
