Wilden Pro-Flo® SHIFT Series
The Wilden Pro-Flo® SHIFT series pumps have been designed to eliminate overfilling which causes stress on the diaphragm and the use of unnecessary air. This leads to savings and a reduced cost of ownership. As the global leader in air-operated double-diaphragm (AODD) pumps, Wilden offers the shift series in both metal and plastic models with bolted or clamped connections to meet the needs of your application.

Design
The air distribution system (ADS) on the Pro-Flo® SHIFT pumps restricts air flow into the air chamber near the end of each stroke so that the only air introduced is what is required to keep the process going. An air control spool optimizes the air consumption and eliminates overfilling with no reduction in flow rate. The design features minimum moving parts, an unbalanced spool to prevent stalling, and a pilot spool to trigger which air chamber is filled.
