Wilden Pro-Flo Advanced plastic pumps supplied by Integrity Pumps and Engineering are specifically designed for maximum performance and efficiency.
Total product containment is ensured with the bolted configuration of the Pro-Flo Advanced plastic pumps while the redesigned liquid path reduces internal friction to maximise output and efficiency.
A variety of elastomer options including Teflon are available to meet abrasion, temperature and chemical compatibility concerns.
The Wilden Pro-Flo Advanced plastic pumps are offered in polypropylene, PVDF and Teflon. Optional fittings such as ANSI and DIN flanges as well as specialised air distribution systems are available to meet specific application requirements.
The Wilden Pro-Flo Advanced Series plastic pump’s patented air distribution system incorporates three moving parts:
- The unbalanced air valve spool
- The pilot spool
- The main shaft/ diaphragm assembly
The air valve spool location directs pressurised air to one air chamber while exhausting the other.
The pressurised air chamber causes the main shaft/ diaphragm assembly to move outward discharging liquid while pulling liquid in on the other side.
When the shaft reaches the end of its stroke, the opposite inner piston actuates the pilot spool. The pilot spool location either pressurises or exhausts the large end of the unbalanced air valve spool.
When the large end is pressurised, the piston is forced up so that the air supply is routed through the air valve spool to the right side of the pump.
When the large end is exhausted, the piston is forced down so that the air supply is routed through the air valve spool to the left side of the pump.
