High-Clearance AutoPump® AP4.5 Ultra

 

 

Low-maintenance, high-performance pump runs for months in wells where traditional pumps fail in days

 

The new AutoPump® AP4.5 Ultra (Patent Pending) delivers superior performance, running many times longer between service events. A pump installed for field testing needed just 30 minutes to clean after 220,000 minutes (348,965 cycles!) of uninterrupted run time – in a well that had been out of compliance for the previous 3 years, requiring pump cleaning every 3 to 5 days.

With a larger diameter and three times the clearance between the float, casing and discharge tube, the AP4.5 Ultra achieves the same flow rate as the standard AP4 with fewer cycles. This results in less wear per  allon pumped, extending equipment life cycle. Greater clearance also enables the pump to deal with high viscosities, solids content and precipitates in the pumped fluid.

Proprietary non-stick finishes combine with the higher-clearance design to reduce solids buildup, increasing the interval between required service events even further. Pump cleaning is much faster and easier,  ften needing only a water spray and a light wipe. Metallic parts are all 316 grade Stainless Steel, resisting corrosion by the harshest leachates and highest temperatures.
