AutoPump AP4.5 Ultra - High Clearance

The new High Clearance AutoPump® AP4.5 Ultra 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.
